“I’m going to Yosemite this summer, what should I wear?” is a question we often get.

Whether you are visiting Yosemite Valley, climbing the Half Dome cables, or are cooling off in one of the park's many spectacular waterfalls, here's what to wear while visiting the Park or nearby Sierra mountains.

Mountain guide Duncan Cheung shares what he’s learned from 15,000+ miles of on hiking trails and off-trail wilderness experience and teaching over 150 people how to backpack minimally in Northern Sierra, including our beloved Yosemite National Park.

Why trust us?

There is no such thing as one-guide-fits-all.  We recognize that our readers’ specific needs and comfort levels are as diverse as the trip conditions that they will encounter from the base of Yosemite Valley to the top of Half Dome, to the high peaks around Tioga Pass. 

Our recommendations are based on Duncan’s over 15,000 miles of on-trail and off-trail wilderness experience, 7+ years of professional guiding and teaching minimalist backpacking, input from Off Trail On Track’s 150+ students, primary research, gear testing, and advice from outdoor experts and community.

What’s the weather like in Yosemite?

This clothing guide is suitable for Yosemite National Park and Sierra visitors who are planning to hike 6-8 miles per day, mostly on established hiking trails between 4,000 to 11,000 ft.

Those elevations cover the most popular hikes starting in Yosemite Valley including Mirror Lake, Nevada Fall, Vernal Fall, Bridalveil Fall, and Lower Yosemite Fall. It also includes mid-elevation hikes in the park such as the top of El Cap, Half Dome, and Upper Yosemite Fall. Lastly, this elevation range includes the higher elevation trailheads including Tioga Pass and Tuolumne Meadow.

If you're spending the day in Yosemite Village or Half Dome Village or walking along the Merced River, you'll be at the lower end of that elevation range around 4,000 feet. At 11,000 feet, you'll be in the high country and may encounter snow, but are still unlikely to need equipment to cross a glacier.

This guide covers “3-season” conditions, with temperatures ranging between 25ºF to 80ºF (-4ºC to 27ºC). In Northern Sierra mountains, that typically means late June to mid-September. 

Falling precipitation is historically low during this time, characterized by afternoon showers and occasional short-lived storms. This guide is applicable if your travels will involve little to no technical or snowy, icy terrain that may require ropes, crampons, and snow/ice tools. 

What to wear in March in the Park

March temps are on the lower end of the spectrum, especially at night. Follow the suggestions on this list, paying special attention to packing more cold clothing, rain gear, and better footwear. For many years, March was an off-season in the Park. Now it has become a more popular time to visit Yosemite Valley as there are cooler temperatures and often limited snow at that elevation. However, higher elevation parts of the Park may be inaccessible to cars due to snow.

What to wear in summer in Yosemite

Peak summer temperatures can get very warm (80ºF and warmer), especially in Yosemite Valley. Pay special attention to pay sun proof gear made with UFF fabric and good sunglasses and a sunhat. 

How should I dress in Yosemite in September?

September days can be pleasant with crisp or comfortable temperatures during the day and cooler temperatures at night. Bugs are less likely to be an issue. 

WHAT TO WEAR IN OCTOBER IN YOSEMITE

Expect below freezing temperatures at night. Bugs will not be a problem. Pay attention to the weather before you go. Snow is a possibility. See our post on how to extend your summer backpacking gear for fall use for recommendations on what gear we pack for cooler weather hiking.

How to Prepare for Yosemite Hiking

Although there are a few gear stores within the National Park boundaries, it is best to assemble and test your gear before you leave for your trip. We recommend trying your gear on a hike near home to make sure clothing fits correctly and doesn't impede your movement. By testing gear at home, you'll reduce the chance you'll have to make do with whatever gear you can purchase in the park. Testing gear on local hikes is also an important way of getting your body physically prepared for hikes you want to do in the Park.

Check guidebooks to decide which Yosemite hikes you want to do during your visit. Make notes of the mileage and elevation gain of those hikes. When choosing local training hikes to test your gear, work your way up close to that mileage and elevation gain. Start slow on shorter hikes with less elevation gain.

The day of your hike: Bring our checklist and mark off that you have everything you need before you leave the trailhead, including gear, maps, and your wilderness permit (if you're on an overnighter in the backcountry in the park).


What to wear while hiking in Yosemite

Whether you seek a strenuous hike with a lot of elevation gain like Half Dome or are on a multi-day trip of the Grand Canyon of the Tuolumne, you will need similar clothing.

For a shorter Yosemite hike that is only a mile or two, like a jaunt to Tenaya Lake or the Giant Sequoia, you may not need everything on the list. But you should still be prepared by carrying the right clothing.

The primary function of the clothing and items that we recommend you wear while you are walking is three-fold: 

  • Keep you drier and more comfortable during exertion

  • Protect you from the sun, intensity, and effect of which is compounded by the high altitude and park's (in)famous reflective granite. This is especially true for people on the Half Dome hike.

  • Minimize injuries and fatigue

There are many ways to achieve the above. Our recommendations below work together to help you travel light, smart, and hassle-free.

WHAT TO WEAR ON YOUR HEAD WHILE HIKING

Outdoor Research Sun Runner Cap

CAP OR HAT FOR HIKING

WHAT TO LOOK FOR

Long-bill cap / full brim hat for better coverage,. This is especially important for when you are hiking on the unshaded, reflective granite terrain that makes the park famous, such as the Half Dome hike. We prefer polyester or nylon over cotton as these materials dry quicker. See our guide to Best Sun Hats for Hiking or Best Running Hats for headwear we like that we think provides adequate coverage.

WE LIKE:

Outdoor Research Sun Runner Cap because it has good coverage, is light, and has a bonus feature: the removable sun cape. The cape is very effective against the ground-reflected sun on your neck and face. Plus, the sun cape doubles as an automatic swatter that keeps mozzies off of your face and ears as you walk!

ALTERNATIVES:

Sunday Afternoons Ultra Adventure Hat is a malleable (think packable) full-brim hat that comes with special holes that keep sunglasses in place effectively.


Yosemite has a lot of white, granite domes which reflect sunlight. Polarized sunglasses are a MUST to protect your eyes from sunburn. Photo by Duncan Cheung.

Buff Merino Lightweight Neckwear

NECK/FACE protection

WHAT TO LOOK FOR

Either lather your exposed skin with sunscreen or cover it with thin cloth/bandana. We find that regular bandana or kerchiefs work just as well as items that boast “SPF protection”; spend your money elsewhere.

WE LIKE:

Caps that have integrated/removable sun capes (see above), or any bandana/kerchief that isn’t see-through.

Neck gaiters/buffs are fine but sometimes not breathable/airy enough.

Goodr OG polarized sunglasses

SUNGLASSES

WHAT TO LOOK FOR

Any sunglasses that “block UV rays,” and not just “tinted/darkened.” Darkened lenses are harmful as they dilate your pupils to allow even more UV rays into your eyes. This can lead to sunburn inside your eyeballs. Polarized lenses are not required but are a nice bonus as they reduce glare and can serve as make-shift polarizers for your camera.

We can’t see ultraviolet wavelengths, but they can damage eyes and lead to cataracts, cancer, and structural damage to the retina. 

Whichever sunglasses you choose, look for labeling that says 100% UV protection (also labeled as “UV400”). This means that the sunglasses can block light rays with 400 nanometers or less in wavelengths (anything bigger than 400 nanometers is no longer UV light). Many inexpensive or gas station sunglasses don’t come with a guarantee to block the three kinds of UV rays (or are falsely labeled) and can actually cause more damage to the eyes than if you wore no sunglasses at all. For more recommendations on sunglasses we like that stay on your head during sweat and movement, see our Best Sunglasses for Running guide.

WE LIKE:

Native Sunglasses as they are lightweight, polarized, and have great peripheral coverage. Another perk is that the arms are metallic, which is a relatively rare these days in sunglasses and we’ve found handy for durability while hiking. 

ALTERNATIVES:

That being said, no need to break the bank on sunglasses as chances are they may get lost. Cheap UV-blocking sunglasses work just as well as $300 brand-name ones. We like GoodR sunglasses, which are designed to be no-slip, no bounce, and polarized.

WHAT clothes TO WEAR HIKING IN YOSEMITE

Icebreaker Merino Women's

HIKING SHIRT

WHAT TO LOOK FOR

  • Length: Short sleeve during high exertion and warmer conditions (≥65ºF). Go with a long sleeve if you’re expecting low exertion or you’ll be in the shade or near cool waterfalls.

  • Material: The key is to keep moisture away from your skin. Light-weight polyester or ~150-175 grams per square meter (gsm) merino wool, or Merino-polyester blend. Elastane in the mix = better movement. For more recommendations on shirts we like, see our Best Men's Hiking Shirts guide or Best Women's Hiking Shirts guide.

WE LIKE:

Icebreaker Merino Tech Lite Short Sleeve T (women's) and (men’s) as the 150 grams per square meter (gsm) fabric weight blocks the sun and dries quickly, doesn’t pill, is naturally odor-resistant. It also is held up well after 150+ days of rigorous use in the wilderness. Bonus: people love the screen-print graphics.

MEC Mochilero Stretch Convertible Pants - Men's

HIKING PANTS

WHAT TO LOOK FOR

  • Cut: The key is to minimize resistance as you lift your legs while hiking. Look for features like “4-way stretch,” gusseted crotch, and articulated knees, and trim fit and minimal pockets to avoid snags.

  • Length: We recommend long pants if you expect to travel through underbrush or if bug pressure is high. Convertible pant-shorts are helpful for swimming but are not necessary.

  • Material: Light, 85%+ nylon, some elastane. “Softshell” is not necessary as they just add weight, resistance, and clamminess.

WE LIKE:

MEC Mochilero Pants (men's). The updated version of the now discontinued MEC Sandbagger pants, their trim cut throughout pant length minimizes snags. It gives me minimum fabric resistance while I'm moving, though this experience may be different for you depending on your body shape and size. It is made of abrasion-resistant material and thick enough that Sierra mozzies don't bite through. See our guide to Best Men's Hiking Pants for more recommendations.

ALTERNATIVES:

My students who identify as women (many of whom are yogis) prefer the Prana Halle II Pant. These pants have the advantage of a trim cut and slightly longer and flared cuff that keep debris out. See our guide to The Best Women's Hiking Pants for more recommendations.

Badger Unscented Sport Stick SPF35

SUNSCREEN

WHAT TO LOOK FOR

SPF 30-35 (rapidly diminishing return when SPF ≥30), mineral-based, water-resistant, with no chemical filters. We like sunscreens that come in “lipstick application” style packaging because it won’t gunk up your hands. See our guide to Best Face Sunscreen or Best Sunscreen for Your Body for sunscreens that we found to be not-greasy and that rub in well.

WE LIKE:

Badger Unscented Sport Stick SPF35. It is weight and space-efficient. Mineral-based sunscreen tends to be gunkier but they are also long-lasting. "Lipstick application" style means clean fingers after application. It is also environmentally preferable compared to ones that rely on chemical filters.


Outdoor Research ActiveIce Sun Gloves

SUN GLOVES AND/OR SLEEVES (OPTIONAL)

A study published in the Journal of Skin Cancer found that most people neglect to put on adequate sunscreen on the back (dorsal surface) of their hands. The same study also pointed out that skin cancers on the hand are more likely to metastasize. Since sunscreen on hands and forearms are easily rubbed off, sun-protective clothing will be more reliable.

WHAT TO LOOK FOR

Any thin polyester/merino sun gloves/sleeves as they will help you feel less clammy, and use less sunscreen. They work by wicking moisture away from your skin and replaces pore-blocking sunscreen on covered areas so your hands/arms will feel less clammy, especially on humid days.

WE LIKE:

Outdoor Research ActiveIce Spectrum Sun Gloves. They are thin and light, and they wick well while offering excellent sun protection.

Suunto Core All Black

hiking WATCH (OPTIONAL)

WHAT TO LOOK FOR

Basic Watch: Basic digital watch with flashing separator/analog with seconds hand helpful for checking vitals.

Advanced Watch: “ABC” (Altimeter+Barometer+Compass) and/or GPS Watch functions are helpful for navigation and weather forecasting. Key: Enough battery for the duration of the trip. Heart-rate monitors and other smart features are not critical. See our story on the Best Hiking Watches for more on GPS and ABC functions.

WE LIKE:

Basic Watch: Any cheap wristwatch that satisfies the above will suffice.

Advanced: Suunto Core All Black. The batteries are easy to find and are long-lasting (months) compared to days for GPS/smartwatches. An altimeter helps navigate when you are off established trails. Reliable in both cold and hot temps. It’s also our recommended pick for ABC watch.

FOOTWEAR FOR HIKING

Inov-8 Roclite 315 Trail Runner

Lightweight running shoes

WHAT TO LOOK FOR

Our experience tells us that it’s better to rely on stronger feet than fancy footwear. While you may be tempted to use a hiking boot, we find better stability by training our feet for uneven terrain. Look for low/no-ankle cuff trail runners that strike a balance between good ground-feel, underfoot protection, and traction. We recommend NON-waterproof shoes as they will dry quicker and tend to be more affordable. See our guide to Best Men's Trail Running Shoes or Best Women's Trail Running Shoes for more recommendations. If you think you'd like to hike with shoes with more support, see our Best Hiking Shoes guide or Best Lightweight Hiking Boots guide.

WE LIKE:

Footwear fit and preferences are very personal. We recommend getting fitted by qualified professionals. That said, I like Inov-8 Roclite 315 Trail Runner (men’s and women’s). They feel like a natural extension of my leg and feet and allow me to sense and take advantage of the micro terrain especially the little nubs and crevices of Sierra granite. For more on what to look for in trail running shoes, see our post on How to choose trail running shoes.


Darn Tough Hiker Quarter Cushion Socks - Men's

hiking SOCKS

WHAT TO LOOK FOR

Light-cushioned merino wool, mini-crew/ankle length. Wear a pair, bring a pair. Socks with thick cushioning are harder to dry and unnecessary. Consider adding gaiters to reduce debris especially if you hike in shorts/capris. Important to avoid cotton as that material retains a lot more moisture, which can make your skin more prone to hot spots and blisters.

WE LIKE:

Darn Tough 1/4 Sock Light (men’s and women’s). Just long enough to reduce debris falling into the shoes. Merino+nylon blend makes them durable, odor-resistant, dry quickly. They are also just thick enough to cushion my feet well without bunching up. Backed by Darn Tough’s warranty, considered the best in the industry. It's the winner in our Best Hiking Socks guide.

What to wear while in camp? 

Whether you’ve just had a satisfying jaunt up the Half Dome cables, ran a loop around Yosemite Valley, or splashed in the creeks at Happy Isles, there comes a time when you are ready to kick back and enjoy a meal and maybe a snooze.  

Heat is hard to come by in the wilderness; we want to trap it close to our bodies whenever we can. The clothing you need at camp/rest, therefore, is primarily to help you retain heat. It can also be worn in your sleeping bag to extend your bag's temperature rating, especially early or late in the season.

Pro tip: Allow time for your base layer to dry off before putting on any filled puffy jackets. Moisture from sweat, waterfall splash, or a swim will dramatically reduce loft on most insulated jackets. This means that your puffy jacket will lose the ability to keep you warm. Fleece jackets don’t lose loft nearly as down- or synthetic-filled puffies. See our guide to the Best Fleece Jackets for more recommendations.

"Mountain Hardwear Dome Perginon Beanie"

WARM HAT/BEANIE

WHAT TO LOOK FOR

Any light-mid weight beanie will do. This is not as necessary if your puffer jacket has a warm hood. We find it helpful if the beanie/hat is made of “wind blocker” material/lining.

WE LIKE:

Mountain Hardwear Dome Perignon Lite. The Perignon provides coverage for the ears and is lined with a wind-resistant material that effectively cuts the windchill.

Montbell Permafrost Light Down Parka

DOWN JACKET

WHAT TO LOOK FOR

A good puffer is one of the best investments you can make for hiking or camping. Why? Because a light, warm, and packable puffer helps to extend the types of trips you can go on (aka, one single item added to your clothing allows you to extend your hiking season into late spring and early fall). We recommend “Down” fill over “Synthetic” fill for the conditions most common in Yosemite and the Sierra. For down-jackets, aim for a hooded, ≥800 FP (Fill Power), with a total weight of 9-18oz, of which, ideally fill material should take up ≥35% of the weight. Box baffle construction will be significantly warmer than “sewn-through” as the box baffles eliminate cold-spots along the seam lines. For more on down jackets, see our guide to the Best Down Jackets. If you think you'd prefer something that is warm-when-wet or vegan-friendly, see our guide to Best Synthetic Jackets.

For more on the differences between synthetic and down jackets, see our post on Which is Better: Down or Synthetic Jackets?

WE LIKE:

We really like the Montbell Permafrost Light Down Parka (women’s and men’s). It’s a shoulder-season-worthy parka (i.e., still works in early spring and the fall, when temperatures can be cooler) and offers a great temperature buffer for unexpectedly cold summer nights. This recommendation is warmer than what you need for the described conditions, we recommend it because we think a quality puffer is one of the best gear investments you can make. Although puffer jackets can be expensive, we think with the Permafrost Line, you get a lot of warmth and quality materials for the price.

ALTERNATIVES:

For those who are in search of a premium ultralight jacket, we recommend looking into the Montbell Permafrost Light Down Parka (women’s and men’s). These won’t be as warm as the Permafrost above, but will work well for the described conditions and have lighter weight, higher quality materials. For those who prefer puffers filled with water-resistant down – which retain warmth longer in prolonged humid conditions – consider the Rab Electron (women's and mens).

LIGHT JACKET

If temperatures drop to ~25ºF (-4ºC) or below, we recommend bringing a fleece jacket in addition to your puffer.

WHAT TO LOOK FOR

Fleece jackets will be heavier and bulkier but much warmer than puffers when they are wet/moist. They retain a surprising amount of warmth even if you’ve sweat through them.

Any brand, cheap mid-weight (~200wt) fleece will do. Since this is one gear item where most brands and models will work the same, if you don’t already own a fleece, we recommend looking at the discount section for past years’ models.

For added performance, “high-loft” fleece will be warmer and more packable. “Windstopper” liner limits breathability so we recommend not paying extra for it. Instead, use your rain gear to block the wind.

WE LIKE:

We like fleece jackets as they are highly breathable and promotes moisture expulsion during those cold morning uphill runs. See our Best Fleece Jackets guide for more recommendations.

Outdoor Research Gripper Convertible Gloves

GLOVES / MITTS

WHAT TO LOOK FOR

Any light to mid-weight (200-wt) fleece gloves or mittens will work well. Avoid synthetic/down-filled handwear as they tend to be less durable and tear easily. This makes them less convenient for camp chores that can be rougher such as collecting firewood.

WE LIKE:

Fleece convertibles (aka glo-mitts). Mitten mode for warmth; fingerless-glove mode for dexterity. Like fleece jackets, no need to pay a premium for brand. Look for glove-mitts that have fold-backs not just on the fingers, but also the thumb for crucial dexterity. We like the Outdoor Research Gripper Convertible Gloves

See our Best Winter Gloves for more recommendations.

ALTERNATIVES:

In a pinch, cheap polyester/fleece gloves from thrift stores or gas stations will work fine.

Patagonia Capilene Midweight Base Layer Bottoms - Women's

WARM LEGGINGS / TIGHTS

WHAT TO LOOK FOR

Leggings / Tights don’t need to be “athletic-cut”; long-johns will work fine. Go for light- to mid-weight polyester or 150-195 grams per square meter (gsm) merino wool. Cotton is ok too if the tights are used only at camp and will stay dry.

WE LIKE:

While specific brands don’t matter as much, my students like the Patagonia Capilene Midweight Long Underwear Bottoms (women's) and (men's). Bonus: Patagonia Capilene series is made with 30% recycled polyester. The Patagonia Capilene is a winner in our Best Baselayers guide and is a favorite for its breathability and moisture-wicking properties.

WHAT TO WEAR IF IT RAINS OR SNOWS IN YOSEMITE?

Outdoor Research Helium II Jacket

RAIN JACKET

WHAT TO LOOK FOR

For most spring, summer, and fall hiking, rain/snow is infrequent and short-lived in Yosemite and the Northern Sierra; your rain gear will likely stay in your pack for most of the time. Look for light and packable rain gear. We recommend a 2.5-layer waterproof/breathable rain jacket with a hood, weighing 5 to 9 ounces. Expect all waterproof jackets to suffer from poor to bearable breathability. Get a size larger than your typical clothing size so that while at camp/rest, you can fit your insulation layers underneath. Do NOT go for “water-resistant” jackets for rain-proofing. In a pinch: gas station ponchos will work fine.

WE LIKE:

Outdoor Research Helium II Jacket (women's) and (men's). It is light, packs into itself, has a great-fitting hood, and is usually on discount. It's a winner in our Best Lightweight Rain Jackets guide, which includes other recommendations.

ALTERNATIVE:

Budget-conscious folks would appreciate a thru-hiker favorite: the Frogg Toggs Ultra-Lite2 Suit (top and bottom) (women’s) (men’s).


Montane Minimus Mitt

RAIN MITTENS (OPTIONAL)

WHAT TO LOOK FOR

If persistent cold rain/solid precip is expected (rare in Yosemite), a light, waterproof “shell/rain mitt” will keep your hands dry and warmer, especially in windy conditions. Get a size larger to fit all insulating layers underneath. They’re generally unnecessary in summer months. In a pinch, use plastic bags or stuff sacks.

WE LIKE:

Montane Minimus Mitt. They are tiny, effective, and they stow well.

Montbell Versalite Pants

RAIN Pants

WHAT TO LOOK FOR

Like other rain gear, these will stay in your pack most of the time. Therefore, aim for a pair that are as light and packable as possible (~3-8oz.) Full-length zippers add marginal convenience but added weight is unlikely to be worthwhile for minimalist backpackers. For more rain pants options, check out our guide to the Best Rain Pants for Hiking.

WE LIKE:

Montbell Versalite Pants (men's and women's). They are light, pack down tiny, and do not have any extraneous moving parts.

ALTERNATIVES:

Rain skirts offer superior breathability with slightly less effective coverage. We like the ZPacks DCF Rain Kilt. Kilt-style bottom means ultimate breathability, though you need to get used to having shins and feet wet. When opened, it can also turn into a dry surface for sitting (or a groundsheet for dogs).

Pro tip:

If cold rain / solid precip is expected to last for 3+ hours (rare), an umbrella in addition to rain top+bottom will keep you much warmer as the cold rain won’t touch your jacket and rob body heat as it rolls off.

WHAT TO WEAR DURING BUG AND MOSQUITO SEASON IN YOSEMITE?

Ticks and mozzies are the two types of insects that we need to prepare for, especially during early to mid-summer months (June - August) on wet years (2017, 2019). As a wilderness explorer and guide, my single biggest fear of all the things that can cause serious harm or death is Lyme Disease. Lyme is tick-borne and while its prevalence isn’t nearly as common in the western US compared to the eastern US, it is under-diagnosed, highly debilitating, and can result in a slow, painful death that lasts years.

The good news is that like many other tick-borne diseases, Lyme is very preventable. While mosquitoes in Yosemite tend to be more of a nuisance than a health risk, they can still affect our experiences outdoors and shorten our hard-earned vacations.

How to keep mosquitos away while hiking:

OUR 4-PRONG APPROACH HAS PROVEN HIGHLY EFFECTIVE AGAINST TICKS AND MOSQUITOES (AMONG OTHER PESKY INSECTS) OVER THE YEARS IN THE SIERRA:

  1. Treat your base layer clothing, hat/neck protection, and socks with an over-the-counter insecticide called Permethrin before your trip.

  2. Wear long-sleeved garments where possible (see above for bonus tips).

  3. Apply DEET / Picaridin onto exposed skin especially around dawn/dusk, and in buggy areas. If mosquito pressure is very high, use a head net.

  4. Check and properly remove ticks during and after outdoor activities, whether you think the area or activity is tick-prone or not. While tweezers are not part of your clothing system, we strongly recommend carrying a pair or a tick remover for prompt tick removal.

WHAT TO LOOK FOR

Permethrin insecticide. Please follow treatment guidelines for maximum safety and effectiveness. We’ve found that each treatment is reliably effective for 4-6 washes. As a guide who works in the wilderness every other week, I’ve found that one Permethrin treatment at the start of the buggy season (June in Sierra) will typically last me through the end of the mozzie season (typically early September). Occasionally I need to treat my clothing twice in the same year. Important reminder: Permethrin is NOT for direct application on the skin.

WE LIKE:

Sawyer Permethrin Insect Repellent for Clothing Gear and Tent. Brands don’t matter much in terms of effectiveness but Sawyer is readily available and comes premixed at the right dosage with consumer-friendly instructions and a spray bottle for easy application.

Sawyer Picaridin Insect Repellent Lotion

MOSQUITO AND TICK REPELLANT FOR EXPOSED SKIN

WHAT TO LOOK FOR

DEET or Picaridin. There is much debate around whether “natural” alternatives such as citronella oil are effective in wilderness areas during high bug season. Our experience: only DEET and Picaridin proved effective.

WE LIKE:

To minimize weight, look for “100%” DEET (which technically is only 98% in active ingredient concentration). Any brand will work but Sawyer Jungle Juice wins out again because it is widely available and generally cheap. Unlike low-concentration DEET (~20%), a small amount dapped and spread only on exposed skin will be sufficient; no need to spray a massive cloud around your body. Judicious application will help to preserve the environment and your synthetic clothing and gear. We like to buy a big bottle and repackage and clearly label 100% DEET in a 0.5oz atomizer bottle, which typically lasts 7-10 days.

ALTERNATIVE:

Sawyer Picaridin Insect Repellent Lotion. Picaridin has an edge over DEET because it does not melt your synthetic clothing and gear. However, we’ve found that it requires a higher concentration and more frequent applications for it to stay effective compared to DEET. It typically comes in liquid or lotion form. We’ve found that the Picaridin lotion is longer lasting than DEET and you’ll end up using less of it throughout a trip.

Sea to Summit Head Net with Insect Shield

HEADNET

WHAT TO LOOK FOR

During heavy bug (mosquito) season, it is worth the 1-oz weight to carry a headnet to keep the pesky swarm away from your head. Pro-tip: get a size large enough to keep the netting away from your face. Pro-tip: treat head net with Permethrin before your trip for even stronger protection

WE LIKE:

Sea to Summit Head Net with Insect Shield. It is helpful to have a headnet that is pre-treated with insecticide
