Best Dry Bags of 2025
waterproof Roll top, zippered, backpack, and duffel dry bags for rafting, paddling, Travel, and water sports
December 17th, 2024
Home> Gear Reviews
Here in North America, we have quick access to dozens of brands and models of dry bags, in a plethora of sizes, that offer waterproof protection, quality, and tons more features and capabilities. Dry bags aren’t just for those on the water like rafters or boaters, but kayakers, canoers, paddleboarders, swimmers, backpackers, anglers, international travelers, multi-sport fanatics, adventure racers, and more.
So how do you choose? How do you pick which ones are right for you beyond eyeing your gear pile and guessing what volume bag you need? Dry bags vary not just in colors and size (shown in liters), but in material, weight, fabric thickness, design, closure type, carrying style, recommended use, level of waterproofness, and more.
If you have a question about any component, brand, best use case, or quirk, I want to be your dry bag guide! I’ve been using dry bags as a paddler, hiker, and traveler for upwards of nine years now. I have my ACA Flatwater and Swiftwater certs, and residing in Colorado, I paddle most months out of the year.
After almost a year of testing dry bags side-by-side, here are the best dry bags for everything from kayaking to rafting to backpacking to international travel, whether for day or multi-day use.

The winners
Best overall dry bag: NRS Bill’s Bag
Best uses: rafting, portaging, multi-day trips
Style: roll top backpack
Weight: 3 lbs. 12.8 oz. (65L)
Dimensions: 14 in. diameter by 24 in. height, 16 in. diameter/33 in height
Available sizes (liters): 65L, 110L
Closure type: Roll top
What we liked: Durability over time, waterproofness, seams, and fasteners
What we didn’t like: Larger volume bag only
Since 1977, NRS’s waterproof Bill’s Bag has been trusted by professionals from the Grand Canyon to the North Pole — a bold claim from the brand, but one that rings true. I’ve been using a Bill’s Bag since 2017, mainly for paddleboarding and kayaking trips, and it’s always held up no matter the river conditions, distance, or type of trip at hand.
This summer, I tested the most recent 65L, a size I haven’t yet used/tested from NRS. The NRS Bill’s Bag is in my book one of the best on market when it comes to price, quality, and affordability. And especially when it comes to holding and hauling lots of gear.
NRS Bill’s Bag
65 L
110 L
The NRS Bill’s Bag 110L vs. 65L sizes, both about 70% full and packed.
The current NRS Bill’s Bag is constructed with a heavy-duty, 21-oz PVC TobaTex body, with a reinforced bottom (34-oz-weight TobaTex fabric), and welded seams throughout. It has a roll top style closure, four compression straps, a (removable) adjustable backpack harness, padded shoulder straps, a round bottom, and grab handles. The 65L expands for over 3,900 cubic inches of storage; the 110L bag offers 6,700 cubic inches of storage. Both bags can be compressed, rolled down and cinched as needed to carry more or less contents. And the removable backpack strap attachment points are really minimalist and flat when the straps are removed; this system on the Bill’s bag is much better than the SealLine Black Canyon pack removable method in our book.
All of the welded attachment points and buckles on the NRS Bill’s Bag are very sturdy. The backpack straps are attached with the same hardware and are very easy to remove and adjust.
Two things I absolutely loved about the Bill’s bag in testing: the construction of the material and the fasteners. Everything is uber-durable, as this back uses aluminum fasteners over plastic, and incorporates compression straps to help cinch down gear. The backpack straps and harness are also adjustable, which is hugely important when it comes to portaging with this bag, carrying to a river or camp, or just simply adjusting to your height for comfort. They are also removable, which makes this bag more durable overall for air travel, and more versatile.
The only con of this dry bag is it’s not PVC-free, and it’s a larger volume bag (65L and 110L options). If you are needing a 40-55L dry bag option, consider our Best Dry Bag Backpack winner, or even some duffel styles.
Best affordable dry bag: SealLine Discovery Dry Bag
Best uses: packing, general watersports, kayaking, paddleboarding, travel
Style: roll top bag
Weight: 300-denier 12-oz main body fabric, 18-oz coated bottom fabric
Dimensions: varies
Available sizes (liters): 5, 10 , 20, 30, and 50L (view option in 5-30L sizes)
Closure type: Roll top
What we liked: Quality construction for the price, versatility, no-frills, PVC-free
What we didn’t like: Not as durable as some others, no grab handle
The SealLine Discovery costs under 50 bucks for a 20L dry bag, making it our best budget winner. It’s a great quality, versatile in volume and size, and isn’t too heavy or too light — it also comes in solid and clear view options. The roll top style is useful for different types of paddling and trips, and is fairly easy to pack. It’s one of my go to dry bags for paddles on my SUP (I’ve tested the 20 and 30L sizes).
This dry bag is also cylindrical with an oval bottom so it’s easier to stand it upright to pack and access items. The polyurethane-coated polyester fabric is PVC-free, and the seams are fully welded, not just taped. This is a quality detail and nice to find on a budget-friendly bag. It’s waterproof but not submersible (IPX7 rating).
SealLine Discovery Dry Bag
20L
50L
It comes in sizes 5, 10, 20, 30 or 50L, and all but the 50L come in the semitransparent Discovery View model too. The Discovery View is equally as great a dry bag as the standard Discovery, however, since light can filter through, contents are prone to overheating and more effects of UV exposure (read more info from SealLine directly on the View bag). Finally, the Discovery comes with SealLine’s limited warranty—which excludes things like standard wear and tear and UV exposure. This is a common stipulation under most dry bags with warranties.
Pros: this bag is durable, has welded seams, and is made in the USA!! And it’s a fantastic price-to-size ratio.
Cons: there’s no options with handles or lash points. It’s the lightest option compared to similar size dry bags (the 50L NRS duffel and 50L Sea to Summit Big River), but the lack of features is the tradeoff there. It also has one of the narrowest bases we tested out of all the cylindrical-shaped dry bags. That’s worth factoring into which size you buy and what items you may want to pack inside.
In terms of dry bags in general, PVC-free is harder to find, though much easier than it was 10 years ago. This bag is also made in the USA. That, combined with its construction and welded seams make this a very durable, quality, and versatile bag. And, the best we’ve tested thus far in terms of price.
Best lightweight dry bag: Sea to Summit Lightweight Dry Bags
Best uses: SUP, kayaking, hiking, travel, day use, shorter overnights
Style: roll top bag
Weight: Varies, 70-denier fabric
Dimensions: Varies; 10.4 x 9.6 x 18.9 inches (for 20L)
Available sizes (liters): 1.5L, 3, 5, 8, 13, 20, 35L
Closure type: Roll top
What we liked: Versatility, light weight, repairable, white interior for increased visibility
What we didn’t like: Sewn seams, not many features
The Sea to Summit Lightweight Dry Bags offer fewer features, but lighter weight. It’s a worthwhile tradeoff if you will mainly be using dry bags atop a SUP or kayak, for packing (whether for water-based adventures, hiking, or travel), or for day uses or shorter overnights. The Sea to Summit Lightweight bags (not to be confused with the ultra-light bags) come in a whopping seven different sizes, all easily able to be color-coded to your heart’s content for organization.

Though there aren’t many features — no lash points or grab handles— there is one awesome component of this bag. And that’s Sea to Summit’s field-repairable buckle design. Yes, the buckles are plastic, but they are fully field repairable. I can’t say enough about this feature: if something eventually breaks, you can repair it instead of replace it! Speaking from personal experience: yes, the buckles are easy to replace if damaged, stuck, or broken. Bonus: if you have several or different models of Sea to Summit dry bags, the field buckle works on nearly all of them.
Plus, I found in testing they ended up being quite durable when carried around by the roll top closure, or when lashed to a SUP. There’s also an included D-ring on the buckle end for ease of tying down these bags. Small 2-3L dry bags are a great size to stash your phone or valuables in clipped to a harness when climbing or canyoneering (which I’ve personally done on a few occasions) — finding uses for these versatile, lightweight bags is endless. If you are using dry bags outside their recommended use, like for waterproof protection while climbing, for example, double-check the brand’s recommendations on use and look into the materials. You’ll generally want a dry bag that’s more durable if it’s going to encounter scrapes or wear and tear against rocky surfaces.
Note: you can also buy the lightweight dry bags as a set, which is a pretty great deal if you need multiple dry bags of different sizes. The sets come in two options: the 3L, 5L, and 8L set of 3, or 8L, 13L, and 20L set of 3, or you can buy them individually. For beginners or those paddlers needing more dry bags for various uses and value lightweight and versatility, it’s hard to beat this bag.
Best dry bag backpack: Sea to Summit Big River Dry Bag Backpack
Best uses: multi-day or overnight trips, rafting, portaging, travel
Style: backpack
Weight: 1 lb 13 oz (for 75L); 420-denier fabric with triple-coated base
Dimensions: 13.6 x 11.2 x 23.7 inches (50L)
Available sizes (liters): 50L, 75L
Closure type: roll top
What we liked: Great volume options for long trips, comfortable to carry, tons of lash points and features
What we didn’t like: Heavier, must buy either the Big River Dry Bag OR the Big River Dry Backpack models separately (its not convertible)
The Big River Dry Bag backpack hasn’t failed me yet on many an overnight SUP trip (I used this bag up at Horsetooth Reservoir and the Red Lakes area), and on one 3-day rafting trip this summer. It’s comfortable to carry, can hold a ton in the way of volume, has a durable interior and exterior, and is an awesome option if you need a dry bag to portage with. The Sea to Summit Big River Dry Bag Backpack is modeled off the brand’s same Big River Dry Bag, just with a different base and added load lifters, backpack straps, and hip belt straps.

75 L
What I like most about this backpack is it doesn’t skimp on features (versus bags that add minimalist removable straps, like the SealLine Pro below), and has thought out tons of contingencies for all different types of paddlers. What does that mean? It provides a durable 420-denier fabric, white interior for visibility, field-repairable buckles, and a flat base for standing up or packing. Plus, important touches like maximum load ratings on the lash points along the side of this bag (which double as grab handles too).
As far as the backpack straps and waist belt go, don’t expect this bag to be as comfortable as a backpack built for backpacking. However, the straps are extremely comfortable and adjustable, and there’s basics like a hip belt and sternum strap included. However, the hip belt is just a strap (no padding, and no hip belt pockets). Overall, this backpack was easy to use across disciplines in testing, performed well, and was comfortable.
Best dry bag duffel: SealLine Pro Duffel
Best uses: travel
Style: zippered duffel
Weight: 2 lbs 3 oz; 400-denier main fabric, 600-denier bottom fabric
Dimensions: 28 x 15.5 x 11 inches (more rectangular compared to rounder or oval dry bags)
Available sizes (liters): 40L, 70L
Closure type: Waterproof YKK zipper
What we liked: Durability, versatility for travel, submersible protection
What we didn’t like: Backpack straps are pretty minimalist, heavy
I spent weeks packing, carrying, traveling with, and schlepping this duffel around. I used it at the lake, on an overnight SUP/camping trip, and on a winter cabin trip to keep my gear and layers dry.
As a duffel, it wins big. The durability of the fabric, the opening and design, the grab handles on four sides (useful for carrying, loading, unloading, and rigging to watercrafts), and the submersible waterproof protection makes the SealLine Pro Duffel a surefire option for long and hard use on or near water. It’s also versatile and equally as durable for air travel if you remove the straps, which can be used as backpack or shoulder straps. Similar to the NRS Expedition DriDuffel (which comes in a 35L or 70L for comparison), this one was much more comfortable to carry. Plus, it ekes out over the NRS Expedition with its higher waterproof rating.
SealLine Pro Duffel
In testing this duffel’s backpack straps, we found fit on testers who are 5’5”, 5’8”, and 6’4”, though the fit and comfort wasn’t perfect for anyone.
Our 5’8” author vs. a 6’4” user tries on the SealLine Pro Duffel and adjustable backpack straps.
Essentially, this is a quality dry bag duffel first, and dry bag backpack second (as a last resort alternate carry method). If you are not on the shorter or taller end (in the 5’6” to 5’10” range), you’ll likely find the backpack straps sufficient and comfortable for carrying shorter distances, like for air travel.
Most Durable Dry Bag: Watershed Ocoee Dry Bag
Best uses: travel, multi-day trips, cold-weather trips
Style: submersible duffel
Weight: 1.5 lbs
Dimensions: 9 x 16 x 8 inches
Available sizes (liters): 10.5L (Ocoee), 22L (Chattooga)
Closure type: Proprietary ZipDry closure (roll top)
What we liked: Durability of material and seams, made in USA, quality, submersible
What we didn’t like: Closure requires two hands to open and a slight learning curve, limited sizes
After tons of testing along rocky and sandy river shores and at countless lakes, the Watershed Dry bag has won in our book when it comes to quality and durability. This bag can handle nearly everything, and is submersible due to Watershed’s unique closure design with the ZipDry seal. The only drawback I’ve noticed on these duffel style bags compared to others we tested is the Watershed Bags don’t open as wide (partly due to the ZipDry closure).

22 L
But, it’s what it’s made of that really counts. The Watershed Ocoee/Chattooga models offer tons in the way of secure waterproof storage thanks to their 840-denier UV-resistant nylon packcloth material (more environmentally-friendly and lighter than PVC), welded seams, and IPX8 rating.
Before we get too into why we like these bags, the model name of the Watershed’s dry bags are all different depending on the size/volume. We’ve used both the Ocoee (10.5L) and the Chattooga (22L) duffel-style dry bags with the ZipDry closure. With the ZipDry closure, these Watershed bags are airtight, 100% waterproof, and finally, submersible — most roll top closures are not.
I also much prefer the ZipDry closure on the Watershed Bags vs other duffels waterproof zipper closures when it comes to cold and freezing temps. Some waterproof zippers can be super stiff, heavy, and difficult to open/close in the cold (like I’ve experienced with the YETI Panga). I’ve never had any issues with the Watershed closure at all in varying temps and situations — on freezing 40 degree days on my SUP, and in hot, summer weather down on the shore of the Arkansas in Buena Vista, Colorado.
Thanks to the unique closure and very durable exterior with welded seams, this bag is fully sumbersible.
While pricey, the Ocoee works great as a small personal bag (store a phone and camera, extra layers, first aid kit, etc.), while the Chattooga offers more volume, and works great as a go-bag, overnight bag, and more. I’ve found both sizes fairly versatile if you are wanting a smaller waterproof and submersible duffel that will last for years. The smaller Ocoee size is great to stash at your feet in a boat or kayak, too — it’s compact but useful, and I’ve never regretted its smaller size.
Note: Watershed is based in the NC area impacted by Hurricane Helene. See our Hurricane Helene help article on organizations working to rebuild. Please consider purchasing from North Carolina outdoor brands. Please also note that the brand may have limited stock at this time, and order shipping may be delayed.
Best compression dry bag: Sea to Summit evac Compression UL
Best uses: overnight trips, ultralight hiking/thru-hiking trips
Style: compression sack
Weight: 3.2 oz (for 13L we tested), 30-denier fabric
Dimensions: Varies; 8.3 x 8.3 x 17 inches (for 13L)
Available sizes (liters): 3, 5, 8, 13, 20L
Closure type: roll top
What we liked: Compression design, grab handle, lightweight, PFC-free and bluesign-approved
What we didn’t like: roll top seal is stitched on and could be better, designed for internal use only
Simply put: the Sea to Summit evac Compression UL dry bag is wicked light, but compresses very well, and uses solid materials (Cordura and eVent fabric) given the bag falls into the ultralight category. In testing, it held up well over time on multiple backpacking and camping trips, and when compressed, is a narrow enough size to fit and adapt to most packs.
Sea to Summit evac Compression UL
Though made of ultralight materials, the evac UL Cordura bag offers stellar features for those wanting some waterproof protection for minimal weight.
Like mentioned above, the four compression straps really do a great job too —this bag is effective at compressing not just random layers or clothes but items like lofty down jackets or sleeping bags. For compressing most sleeping bags, you want the largest size (the 20L), though always check your sleeping bag size and dimensions against the capacity for these bags. For example: the 13L size I tested fit a variety of synthetic and insulated jackets, layers, and one summer 30-degree rated sleeping bag.
The feature on this bag I probably used and noticed the most (besides the obvious compression straps) is the grab handle on its base. This makes it so easy to reach, rotate, and access when it’s inside your pack.
The weight of this bag (just over 3 oz for the 13L I tested) is also impressive considering all the hardware and straps needed for the compression design. The seams are sewn and taped (an important reinforcement since compression sacks typically get stuffed more than other bags), and the base of the bag is reinforced, while the rest is kept as light as possible. Lightweight materials and construction is the name of the game here, and for good reason.
There is a heavy duty version of this compression sack, with the same reinforced elements, but it uses thicker fabric and is heavier.
Important note: this dry bag and some like it are recommended for “internal use” only—as in, inside another bag or pack. It’s not designed to have the highest level of waterproofing or be submersible. So this bag is a great ultralight option if your focus is on reducing weight, saving space or compressing items, and waterproof/extra protection.
Other dry bags we tested
SealLine Black Canyon Backpack 65L
Best uses: long multi-day trips or long portages, rafting, use when you don’t care about weight
Style: backpack
Weight: 3lbs
Dimensions: 25 x 17.5 x 9 inches
Available sizes (liters): 65 or 110L
Closure type: roll top with compression
What we liked: Premium comfort and durability
What we didn’t like: Added weight, pricey, other packs we tested were similar in features
This dry bag backpack would have easily beat all the other dry bag backpack or backpack-convertible options if there were an award for “Most Comfortable.” However, looking at the pack holistically with all its other features, it was a tough one. Ultimately I found this pack very heavy (it’s well over 3 lbs), and the whole removable strap and waist harness system a little quirky. (The NRS Bill’s Bag removable straps are MUCH easier.)
SealLine Black Canyon Backpack 65L
65L
115L
Finally, this pack is nearly $100 more than our Best Dry Back Backpack winner, and that’s a huge difference for a pack of a similar size with a lot of the same features (padded straps, load lifters, lash points, and a visible interior). It’s also over a pound heavier. That’s a tradeoff to consider: you’ll pay in dollars and weight for more comfort with this pack.
That being said, this pack is equally if not more durable with its 600-denier body fabric exterior, compared to our backpack winner’s 420-denier fabric. The SealLine Black Canyon has padded lumbar support, and better comfort; the Sea to Summit Big River has more lash points and keeps weight low. They both have straps, a hip belt, and sternum straps. Weighing size, weight, and value here is what it came down to, as both proved uber-durable in testing.
If you are in the market for the dry bag and know you will be carrying large amounts of gear (think a 60+ to 100L bag) canoeing, kayaking, portaging, or canyoneering, this dry bag backpack could go on your short list.
Best uses: travel, camping on/near water
Style: zippered-duffel, backpack-convertible
Weight: 2 lbs 3 oz; 400-denier main fabric, 600-denier bottom fabric
Dimensions: 28 x 15.5 x 11 inches (more rectangular compared to rounder or oval dry bags)
Available sizes (liters): 12L, 35L, 70L, 105L
Closure type: DriDuffel zipper
What we liked: Durable and airtight, IPX7 rating
What we didn’t like: Not as comfortable to carry on the shoulder, no backpack strap options
The NRS Expedition DriDuffel duffel-style dry bag performed well in testing. I took it on several river trips and also a short trip to the coast of Florida. It served me well as a travel bag and carry on (the 35L size), though the carry options were not comfortable. Plus, there’s a lot of straps (handles/compression strap ends) that flap around if you aren’t using the tote handles to hand carry, for example. These aren’t removable for travel.

70L
105L
The exterior of this dry bag proved foolproof in the back of a truck, and outside in the rain. (I also dunked this one, with all my clothes inside mind you, in a pool for the sake of testing). I used the compression straps to cinch down the bag almost every time I used it, whether on my SUP or raft, or for travel. That feature is sound. It’s waterproof, it’s durable… it’s just not as good as our other backpack and duffel winners in terms of overall use and comfort. Others simply beat it.
Another note I had after comparing all the bags we had in testing: there’s a huge jump in the volume options for this bag, which is odd to me. NRS misses out on making a slightly larger and more capable personal size in the 20L range, and maybe a 50L bag (which other competing brands offer). (The 70L option is much too large for carry-on travel.)
Best uses: Hiking and backpacking
Style: roll top hand-carry, packing dry bag
Weight: 1.6 oz (40-denier fabric)
Dimensions: 6.69 by 8.6 by 13.78 inches
Available sizes (liters): 3, 5, 12, 20, 35L
Closure type: roll top
What we liked: Super lightweight, great for travel, bluesign approved
What we didn’t like: Stiff roll top rim, IPX5 was the lowest rating we tested, these dry bags are mostly just meant for packing, organization, and travel
The Osprey Ultralight dry bags are great for their intended use as a supplementary accessory for hiking or backpacking, or maybe travel. These dry sacks have some thoughtful touches, like a narrower base to shave weight but they still have a wide opening for ease of packing, for one. We also liked the added small loop of fabric at the base to hang to dry or air out after a trip or cleaning. And thirdly, though this is minor it’s one hikers will appreciate: the logo on the outside of the dry sacks is reflective so you can easily find inside your pack, tent, or at camp in the dark.
Osprey Ultralight Dry Sacks
Now for some cons: I had several issues with the roll top design. First, the fabric loops attaching the buckles aren’t the strongest (compared to most roll top bags that use a Hypalon rubber fabric that also creates a better seal). These are a possible failure point. Secondly, the ultralight bags I received for testing all had super stiff roll top rims. I had to store them flat, and unfold them and refold them and buckle them several times to “break it in,” you could say. I’ve rarely seen such a stiff roll top on other lightweight bags. Though, I did really like the buckle, as it was easy to open and close one handed.
Ultimately, these are a really great option for hikers, but their closure design and waterproof rating is why they didn’t rank higher on our list. If you are going for ultralight, you can consider our Compression Dry Bag UL winner.
Best uses: packing, hiking, lightweight travel
Style: rolltop bag/compression
Weight: 2.7 oz (15L)
Dimensions: 5.5 x 10.4 x 18.8 inches (20 L)
Available sizes (liters): 15, 20, or 30L
Closure type: roll top
What we liked: usefulness
What we didn’t like: durability
I really liked the usefulness of the SealLine Blocker PurgeAir dry bag. The PurgeAir is SealLine’s proprietary one-way valve on this fairly lightweight dry bag. However, it’s the same valve that’s on SealLine’s Discovery View dry bag, which is a significantly more durable option (300 denier fabric vs. 70-denier on the ultralight Blocker dry sacks).
SealLine Blocker PurgeAir
The Blocker bag is shown on the left; the right bag is the SealLine Discovery with the PurgeAir valve option.
This dry bag is a good option for general use as a packing and compression sack (if you don’t want to deal with buckles or compression straps), but isn’t as durable or as highly waterproof as others we tested. Also, maybe not a factor for some consumers, but for those who care about the carbon footprint of their gear: the SealLine Discovery and Discovery view dry bags are made in the USA, while the Blocker line is made in China.
Best uses: multi-sport or multi-day trips, packing, travel, paddleboarding
Style: rolltop bag
Weight: 10.9 oz (for 35L)
Dimensions: 12.5 x 11.1 x 23.1 inches
Available sizes (liters): 5, 8, 13, 20, 35, or 65L
Closure type: Roll top
What we liked: Lots of lash points, very durable
What we didn’t like: The backpack version of this dry bag won us over by a hair
While the Sea to Summit Big River Dry bag is a quality bag and comes in a multitude of sizes, the Backpack version of this same bag is as good in quality and slightly more versatile and built out in design. If you don’t want a backpack or duffel style dry bag, and also don’t care if a dry bag is lightweight, you can consider this bag, for sure.
Sea to Summit Big River Dry Bag (non-backpack)
While it comes in more sizes compared to the Big River backpack version, the 65L size isn’t very useful unless you are strapping down to a raft or larger watercraft. If you are looking for a larger size dry bag for this use, I’d consider comparing this bag with the 65L NRS Bill’s Bag and choosing between the two.
What to look for in a dry bag
Reflecting back to the early days of whitewater (circa Jack’s Plastic Welding in the ‘80s), and looking ahead to now, gear has come a long way — not just rafts and boats, but dry bags too.
Water-based adventures would be a lot less fun if we didn’t have the technically-sound, innovative, waterproof wealth of variety of dry bags we have today. (I was recently reading a book about a Siberian paddling adventure that took place in the early ‘90s…and all they had were canvas sacks lined with trash bags. Yes, much of their gear got wet.)
Waterproofness vs. Submersible (seam construction, material, closure type)
There’s a whole section on waterproof ratings and specifications below, but the short and sweet version is that there’s a difference between waterproof fabrics (like on packs), waterproof bags (the entire unit), and submersible bags. Waterproof bags, aka dry bags, are the bulk of what we’ve reviewed here, but there are a few submersible options on the list as well. Roll top closure-style bags can never be categorized as submersible because of that style of closure.
Submersible bags on the other hand typically have a different type of seal or closure, like a waterproof and airtight zipper, that makes the bag rated to submersion. In these bags and in burlier and higher-end dry bags as well, you’ll also find RF welded or welded seams, as opposed to just sealed or bonded seams. Waterproof YKK AquaSeal zippers are a common standard you’ll see on fully waterproof/submersible dry bags, too.
Material durability
The top dry bags that we’ve found for submersion, harsh conditions, and durability over time are these types of bags — heavier duty fabrics like double-coated or laminated polyurethane and high-tenacity or ripstop nylon. The higher the better when it comes to strength and durability — 400 to 600 denier fabrics make up dry bags in the “heavy duty” category.
I also prefer buying dry bags with welded seams instead of seams sealed or bonded with adhesive, as adhesive can degrade more easily over time. You’ll find several dry bags we tested including some from SealLine, Watershed, and Sea to Summit have welded seams.
Size and capacity
For this review, I tested dry bags ranging in size from 3L to 70L, but I also own and have previously tested dry bags from 2L up to 100L. If there’s a really specific size dry bag you need, someone’s got it.
For everyday or day trip use, dry bags sizes 5 up to 10-12L are great — they can hold small items, first aid kits, cellphones, snacks, a water filter, etc. Many brands are now jumping on board making clear, see-through, or view pane dry bags for this reason: it’s visually awesome to know what’s stashed inside, especially when it comes to maps or first aid.
A couple of my favorite “personal carry” dry bags (for quick access atop a SUP or packraft, or even lashed down in a raft) are in the similar 10-20L range. For packing for a longer overnight trip like a river trip, I stick with larger bags, 30 to 55-65L, and organize my gear accordingly. If you are just starting out a new water sport, it’s a good idea to invest in at least two dry bags — a smaller option and a larger option that can fit the bulk of your sleeping and/or camping gear.
Features (straps, handles, lash points, additional pockets)
One of the most important “features” of dry bags in my book, after their waterproof rating and material/denier fabric, is grab handles. You want dry bags to be versatile, easy to use and carry, and accessible. At least one grab handle on the end or side of a dry bag is really useful.
You’ll also want to look closely at how extras like lash points and handles are added to bags: are they sewn on, bonded with adhesive (fully-taped), or welded? Welded would be the strongest and most durable of the three. Dry bags that have unique shapes, more pieces added, or use welding over bonding are going to be more expensive. But useability is huge, so get a dry bag that fits for the sport, activity, and amount of use you anticipate.
Fun fact: many dry bags make the inside of the bags white for the best visibility for finding and digging for gear inside. If you are using a dry bag for overnight uses, consider a bag with this feature.
Ease of use
If you are buying a new dry bag for your first ever canoe or kayak trip, heads up! You might have to portage with it! And that means carrying all your gear and your boat and equipment around an obstacle, or from one body of water to another.
Backpack-style bags are essential here, or bags that you can store in the canoe or boat while you portage. When buying a dry bag, you don’t just want to think about what you’ll need to carry, but how you want to carry it. If you are hiking really long distances with a dry bag, you may want to consider one with padded straps, or even a hip belt (which narrows your options).
You’ll also want a dry bag that, if hiking or thru-hiking, fits the gear you want protected, but also fits and packs down nicely into your pack. For example, you won’t need bulky extras like handles or extra pockets on bags for this use.
Weight
The weight of dry bags across the board varies widely. But when you look at dry bags of a similar size, I find it much easier to compare. Most dry bag manufacturers will list the product weight as well as the fabric type and weight. For example, Sea to Summit’s lightweight dry bag (5L) weighs 1.8 oz, whereas the Sea to Summit Big River dry bag (in the same 5L size), weighs 4.8 oz. There’s a big difference in fabric weight here: 70-denier nylon vs. 420-denier nylon, plus, the Big River bag has lash points and reinforced seams, whereas the lightweight bag is more no-frills.
In addition to weight, you can easily find dimensions for dry bags listed online if you are comparing different bags, as well as the interior space, which is super important. A 5L bag might be 305 cubic inches, whereas a 75L bag is 4,576 cubic inches. This is a helpful metric if you are trying to gauge how much space you need.
Temperature resistance
Dry bags are by design extremely durable, abrasion resistant, reinforced, and should last a long time. But there’s one factor that can affect the lifespan of your dry bags that’s sometimes unavoidable: heat/UV exposure.
Being outside all day on a body of water means exposure to not just water and the elements (like rain), but prolonged sun and sun glare. Some dry bag makers consider this and build their bags with UV-resistant materials. If you are looking at larger bags with features like D-rings and clips, consider if they are plastic or metal (which can be hot to the touch if your bags are in the sun).
Finally, consider dry bag manufacturers that offer a lifetime warranty. Frequent, hard use in the elements is what dry bags are for, and you ideally want to be able to repair, replace parts, or file for a warranty fix if needed.
Visibility and safety
Like puffy jackets for those who hike or climb, or tents for those who spend lots of time in the backcountry, neon or bright colors like yellow and orange are never a bad idea. Plus, you’re less likely to lose or misplace a dry bag along a beach, in the dark, or say, in someone’s trunk (yes, I’ve done that). Bright colors are easy to see and can help in an emergency or rescue situation on the water, but at the very least, help you to visually spot your gear.
Some brands will color code each of their sizes, and I know paddlers who do the same for the sake of organization. My pin kit for rafting, for example, is always in a designated bright yellow dry bag, and I often try to stash emergency and first aid gear in a smaller red or orange dry bag. It’s a good idea as well if paddling or traveling in large groups, to ask people in which bag their emergency gear is stashed — especially if anyone on the trip has any medical conditions or allergies.
Side note: I’ve never understood who would ever buy a black dry bag! Not to mention, when you’re on a SUP far away or on the ocean in a kayak, black is nearly impossible to see. Plus, black and dark colors absorb more UV rays than lighter colors. It’s worth picking bright or lighter colors for this reason, or if you really want a black or dark bag, make sure it’s a brand that uses UV-resistant materials. Try not to leave a bag out all day in the sun, if you can help it. Always wash, dry, or spot clean and then store away unrolled indoors — not outside.
How to choose the right dry bag
Packing up and stacking various sized dry bags in our early testing for comparisons on size, volume, and weight.
General water activities:
Choose bags with medium to high denier fabric/high durability and flotation for kayaking or boating. A small roll top bag for general day trips, occasional paddling, or beach use is a safe bet, something in the 3-10L range. You can clip these to a SUP or kayak easily via the roll top buckle, and many of these style bags also have D-rings.
For canoeing or boating when weight doesn’t matter as much, you can choose heavier fabric or heavier weight dry bags. For rafting or other paddling trips, the type of bag you choose might depend on size, carrying capability (can you portage with it), or even how durable the fabric is (look for heavy duty or thicker PVC bags).
If you are a beginner buying your first dry bag(s), consider what you need to pack inside: lay out all your gear or things you know you’ll want to bring with you/keep dry, to gauge the size of bag you’ll need.
Human-powered water activities/multi-sport:
Mary tested dry bags on a multi-day Colorado River Class II/III trip.
Think a bikepack-bikeraft trip or a backcountry packraft, kayak, or SUP trip. Choose lighter weight dry bags with at least IPX7 — I like to be able to rely on higher waterproof-rated bags across multi-sport activities or long days on the water in the backcountry. Juggling light weight and durability is a balancing act, and totally up to your own preference here.
Lash points and multiple grab handles also really make a difference when you are strapping gear down to your watercraft. Cylindrical roll top bags work extremely well for lashing to bikes, and well as fitting inside packraft chambers. Some people on long-haul lake or river trips will prefer one very large big bag — like an NRS Bill’s Bag — or one or two larger bags for organization, and then a “personal” size bag as well.
No matter what type of trip I’m on where I need dry bags, I almost always have at least two, a larger one for main gear storage, and a smaller one for day-use and easily accessible items (a phone, sat phone, camera, or first aid kit).
Thru-hiking/Hiking/Backpacking:
Opt for lightweight, “customizable” size-appropriate bags with features for ease of packing and efficiency. Consider dry bags with purge valves to get out air, keep contents compact, and save on space/weight. The lighter the fabric the better, generally! For hiking and backpacking and general water protection, you aren’t going to need (or want) the highest-rated or burliest dry bags — it’d be overkill, and you’d just be carrying extra weight.
But if you know you will encounter really rough weather or conditions, consider a step up from ultralight dry bags (bags with a higher denier fabric will be more durable). In a pinch, I’ve even used some heavy duty dry bags for a bear hang. And when stuffed with soft clothes, they can double as a pillow.
For compression bags or sleeping bags, it helps to go to a store and ask what recommended compression sack size you’ll need for bags, as they can vary widely based on fill, packability, length, and weight.
Camping:
Why buy a dry bag for camping in general? They are great if you are camping somewhere wet or along a beach or coast, to ensure that dirt, sand, and water stays out and your gear stays dry. Select larger, feature-rich bags for car camping with wider openings. The beauty of dry bags is anything can go inside! Your tents, sleep system, camp chairs, and more. Bigger in this case is usually better, but make sure you get a bag with a carry option like backpack or shoulder straps if you anticipate walking/hiking to a campsite.
Duffel-style dry bags are a good choice if you frequently camp outside in adverse conditions and want that extra level of protection for all your gear. I’d also highly recommend a Bill’s bag for anyone doing backcountry lake or river camping. The 65-110L bags are a huge catch-all that can hold pretty much everything.
Extreme weather conditions:
Pick bags with materials suited for extreme cold or heat/sun exposure, and with a higher waterproof rating. I’ve found that some clear or coated dry bag materials can condense or sweat easily with temperature swings. Remember, darker colors like black, browns, or dark blues will fade more quickly over time with UV exposure. If your bags will be riding on top of a raft for 8-10 hours a day, consider dry bags made with UV-resistant materials or lighter color bags.
Also consider cold or freezing (and below freezing) temps. I’ve had trouble in the past with moisture or water freezing over waterproof dry bag zippers, making them difficult to open. Roll top bags may be a better choice if you frequent winter backpacking or camping in the snow. If you can, always store your dry bags away from intense heat, campfires, and prolonged direct sun. The same goes for freezing temps: store your dry bags with you in your tent or shelter if possible.
Travel:
Use compact, easy-to-carry bags (read: backpacks!) for air travel and duffel-style dry bags for international trips (this is my preference and typically better for checking/schleping/and packing. Having either backpack straps (removable hip belts are a fantastic though uncommon feature on dry bag backpacks) or a shoulder strap is essential for a dry bag duffel or bag for travel. You can usually get away with 30-50L dry backpacks/duffels as carry-ons, but always check with the airline dimensions.
Definitely factor in durability if you will be using a dry bag for situations other than outdoors and air travel — opt for a higher denier or thicker fabric, and be sure you look into the carry options each bag offers for what will be most comfortable for you. I’d also recommend getting a bag that has a couple different carry configurations, and grab handles. SealLine Black Canyon backpack even has an included strap designed to help compress the bag so that it’s more comfortable to carry.
Our verdict: even when weighed down and full, this backpack is extremely comfortable, thanks to the combo of the strap design and the padded back and hip belt. I barely even noticed the weight.
Difference between a dry bag and a waterproof bag
There is a HUGE difference between a dry bag and other waterproof bags or packs. In other words, dry bags are specifically for waterproof protection, and then waterproof bags for other general outdoor uses. Regular waterproof bags or backpacks may have a waterproof coating on zippers or seals to help keep weather and moisture out from openings, or a waterproof treatment on the fabrics, in addition to general durability to keep dust and dirt out. But many of these bags are not fully waterproof. (I always ask myself, would I trust it if I put my phone inside and dropped it at the deep end of a pool?)
A dry bag, on the other hand, is technically designed to withstand a certain amount of water, water pressure, splashing, dunking, or submersion, as indicated by the IP ratings scale. The IP rating, which stands for ingress protection, has two numbers, indicated by the formula IPXX. The first X or number indicates the level of protection for the “solids” rating: think rocks, dust, dirt, and grime. The second number is the “water” rating — the higher the number, the higher the level of waterproof protection it offers.
The majority of dry bags we tested are IPX7 or IPX8. IP67 is also a very common rating, especially among roll top bags — where the 6 stands for “dust tight” against solids and the “7” stands for waterproof.
Here’s a quick guide to the differences in the higher waterproof dry bag ratings:
IP67: dust-tight and waterproof up to 1 meter for 30 minutes
IPX7: waterproof when submerged up to 1 meter for 30 minutes (i.e., “dunkable”)
IPX8: waterproof when submerged in a depth up to 3 meters
IPX9: waterproof and protected against “high-powered water stream jets” (essentially, pressurized water protection) — typically you won’t find this rating on dry bags but may see it elsewhere
Submersible: waterproof and rated to continuous submersion
Sometimes you will see dry bags omit the first number and leave an “X” (which stands for not tested) in the solids column, as the main objective of testing and rating these bags is water protection. Few dry bags are actually rated for full submersion; these are called “submersible” dry bags — most are only rated to some submersion to a certain depth, about 1-3 meters. Submersible dry bags have their place in some cases (long and hard use on rafting trips, etc.) but are also more expensive. These would not be necessary if you just want a dry bag for protection at the lake, river, or against rain on the trail. A dry bag with a high waterproof rating and durable exterior fabric should last you a long time in the field.
How to properly pack a dry bag
Dry bags are great because you can pack soft items very tightly, and purge any extra air to save space and weight. For bulky or hard items, I tend to pack them towards the upper half and center of a dry bag — packing other gear around it if possible. Avoid pushing sharp or rigid items (tent stakes, backpacking stoves) towards the edges, or packing too tightly.
This is important: do not overstuff your dry bags! Always make sure you have some room at the top of the bag to purge air, and close correctly (especially if it’s a roll top closure that requires three or more rolls to seal). If you are packing all soft items or compressible items like a sleeping bag or jacket, compression dry bags with compression straps can really come in handy too for reducing bulk and packing as tightly as possible.
Down and very lofty items can pack down more than you think, however, do NOT overstuff your dry bags! You can damage the material and will have trouble getting the correct waterproof seal, or good compression out of a bag.
Whatever you are adding to the bag, you want to pack neatly. I always roll or fold clothes together so they take up less space. You’ll also want to pack like items together, for example, pack all your sleeping items into one dry bag, and your tent into another. Sometimes, this doesn’t work though and your vessel will dictate how you have to pack — packing dry bags into chambers in a packraft will be dictated by a certain size dry bag, and rely more on balancing out bulk/weight. But generally, I like the rule of packing related items together — and, it helps you stay organized when you get to your destination!
Packing items into a dry bag for waterproof protection into, say, a backpacking pack means you can also choose lightweight or ultralight materials to keep the weight down, but achieve waterproof reliability. For important items you need accessible, you can also consider clear or “view pane” dry bags that allow you to see the contents within. This is incredibly helpful for maps, first aid kits, repair kits, and other items you may need accessible from a raft, boat, or kayak.
Dry bag care and maintenance tips
Cleaning
After a trip, whether it’s a day trip or several weeks on the river, you want to unpack, unravel, and clean your dry bags. I typically wipe down and spot clean the exterior, and leave them hanging to air dry. Hangers with clips, a clothesline, or a line in a garage is a great way to do this. Also, don’t forget the inside! PVC-type dry bag materials are easy to wipe clean. If any of your gear that was stored inside was sandy/dirty, it’s not a bad idea to shake clean and wipe down the inside with a damp cloth. Just make sure you let it air dry open too.
Always take the extra time to spot clean (or gently hose down if you were at a sandy locale), and clean any dust, dirt, or sand out of buckles, seams, and bag closures. I love using small microfiber cloths to help clean the inside of buckles, creases, and corners thoroughly.
Inspect for Damage
Before and after trips, I also get in the habit of inspecting my dry bags for any scratches, or micro-tears that could lead to holes or jeopardize the integrity of the bag. Dry bags are extremely durable, but if they are knocked around, dragged, roughed up on a rocky riverbed, or overstuffed, they can fail.
Tips for Maintaining Longevity
Many brands also sell seal protectant, also called lube or silicone lube, to help keep the waterproof seals or waterproof zippers sliding well, and this really helps preserve the longevity of these types of dry bags. Common ones to look for are TruZip’s lubricant wipes or Watershed Drybag’s 303 Rubber Seal Protectant.GearAid and NRS also sell lubricants for dry bags and waterproof gear. (Note: do NOT buy or use waterproofing liquid or spray. Always check what the brand recommends in the manual, or consult the brand if needed.)
Care & Storage
A note on how to store your dry bags: leave roll tops un-rolled and unclipped. This helps prevent the bands at the top from permanently creasing or folding in one direction. You can store smaller dry bags inside larger ones. I have a 75L dry bag backpack that I actually use for this purpose at home — it houses all my other dry bags within.
How we researched and tested
Though I’ve used many of these brands or bags before for my own personal use, they have been updated or changed recently, so I tested them side-by-side for comparison. I went all the way back to the start line, researching each bag to confirm its specs, recommended uses, and recent reviews. I wanted to let my experience and prior knowledge of dry bags be a baseline, but not an assumption, or steer my research. Finally, I worked with the Treeline team to compile our initial list of dry bags to test for this review.
Mary on a section of the Colorado River, late summer.
I used a variety of these dry bags when kayaking, paddleboarding, packrafting, camping on river trips, backpacking, traveling, and swimming. I also used a few on day trips to the creek near my home, and on rainy days. I brought a few on an international trip to Mexico and a trip to Florida to see how lightweight dry bags fare for water and weather protection, and how duffel and backpack style dry bags fare for traveling. Also, the duffel style dry bags that were in the running each got tested on their own trips separately. Finally, I took a full day to pack and repack my gear list for an upcoming river trip in different and various sized dry bags we had in the running.
Testing dry bags in and on the water on a gorgeous SUP day in Colorado.
The bulk of the dry bags tested were used thoroughly on, in, and near the water. The other important testing component I checked was their weight, materials, and packability. Finally, I submerged each submersible-rated dry bag (there were 4) to roughly 2 ft/1m in the water for 5 minutes to simulate a proper submersion and waterproofing test. The rest of the bags in testing were all splashed, dunked, and hosed down too for the sake of waterproofness verification.

Paddling is one of her passions: if it involves a river, ocean, creek, canal, tributary, or alpine lake, she’s in. For the past 8 years, Mary has completed countless pack-paddleboarding (backcountry paddleboarding) adventures out West, from Colorado to Utah to British Columbia. Mary has her ACA SUP Instructor, ACA Flatwater Rescue, and ACA Swiftwater Rescue certifications. She’s done many floats and river trips on the Colorado, Green, and Arkansas, both via kayak, packraft, and SUP, in groups and solo.
In college, Mary and her friend set a self-supported record, being the first (known) team to complete British Columbia’s 116km Bowron Lake Canoe Circuit self-sufficient on SUPs. After college, Mary worked for an outdoor skills camp, teaching kids the joys and essential skills for kayaking, paddleboarding, and more. She still gets out on rivers and lakes whenever she can, and can likely be spotted on her trusty SUP up on an alpine lake, or her packraft downriver somewhere along Colorado’s Front Range.
