Long gone are the days when getting pregnant meant having to hole up in the house and avoid activity for nine months. Quite the opposite: Most pregnant people are encouraged to maintain or begin physical activity for both their own health and their baby’s. And while every person and pregnancy is different, the general rule of thumb when it comes to exercising when pregnant is that if you did it before becoming pregnant, you can continue it throughout pregnancy (within certain limitations). 

Even before pregnancy, in the early stages of planning for a family, I was determined to keep up all of the outdoor activities I love—biking, backpacking, running, and skiing, to name a few. In the early months of pregnancy, aside from some unusually intense fatigue and a need for regular cat naps, staying active in the gear I had used before was pretty easy. For all of the first and some of the second trimesters, I had running shorts, bike shorts and chamois, and technical leggings that continued to fit. I wore my regular go-to apparel for hikes and bike rides, backpacking trips, and multi-day paddling trips. 

I’ve been determined to buy as few new clothes as possible during this stage of life, primarily for sustainability and practicality reasons. It seems silly to me to buy a brand-new pair of pants that I’ll wear for only a few short months before they become useless. I’ve been able to find many pieces that are already in my closet that have transitioned with me through pregnancy (with some modifications). 

But every pregnant body is different, and as pregnancy progresses and we grow, staying in the same clothes isn’t always possible, or at the very least, it’s uncomfortable. In many cases, there’s still a need for maternity-specific gear that will work with your changing body and perform out on the trail. 

Truth be told, most of the top outdoor brands aren’t making maternity-specific apparel, and finding clothes that keep me on the trail hasn’t always been easy.

These are the best options for gear and apparel for pregnant outdoors people who want to remain active outside, based on my personal experience through pregnancy and with years of gear testing under my belt. It’s a combo of regular gear that I found to work for me throughout pregnancy (hooray for not buying more stuff when we don’t necessarily need it!), plus some maternity-specific pieces that can be simply necessary for a growing belly that needs coverage and support. 

It’s worth noting that no matter what you’re used to or what outdoor activities you plan to keep up with during pregnancy, you should always discuss this with your doctor before heading out on the trail or into the backcountry.

MATERNITY APPAREL FOR ACTIVE PREGNANCIES

WHAT TO LOOK FOR IN MATERNITY OUTDOOR GEAR AND APPAREL

WIDE, STRETCHY WAISTBANDS

Whether you’re looking for maternity-specific pieces or just sorting through your closet to find what might work as your bump gets bigger, there are some factors to keep in mind. When it comes to shorts and pants, avoid anything overly constricting. There are all sorts of weird things happening inside your belly during pregnancy, and tight or restrictive waistbands don’t do any favors for comfort. Opt for wide waistbands that offer support without being too restricting.

HIGH-WAISTED OR BELOW-THE-BUMP PANTS

In my experience, going either high-waisted or low-waisted works best. Things that hit in the middle often just aren’t as comfortable. As your belly grows, opt for either high-waisted (and stretchy) options that go over your bump. Or, wear pants and shorts that hit a low rise to fit comfortably below your bump.

HIGH-COVERAGE TOPS

Tops are less complicated as long as they provide the coverage you want. Your favorite cropped tees won’t fit anymore during pregnancy—unless you really want to show off your bump, more power to you! If you want more coverage, look for tops with longer hems.

JACKETS WITH FLEXIBILITY

When cold weather hits, jackets with double zippers work wonders to leave space for your belly as it grows. Jackets with a little stretch work well too, like softshells as opposed to hardshells that are more rigid. 

QUALITY MATERIALS, CONSTRUCTION, AND FEATURES

Aside from fit, I wanted my clothes to function just as well as before pregnancy—good wicking materials, pockets, and durability remain priorities for outdoor gear. And that’s one of the reasons I modified my current gear to keep it in rotation as long as possible. I tried to avoid spending money on cheaply-made maternity clothing that would not meet the demands of outdoor activities whenever possible. Don’t be afraid to get creative—like adding hair ties or rubber bands to bridge the gap from your button when your pants get too tight—in order to continue using what you already have.


THE BEST OUTDOOR GEAR TO USE DURING PREGNANCY

LIGHT COMPRESSION HIGH-WAISTED LEGGINGS

I found that many of my leggings continued to fit throughout much of my pregnancy, though some of the more compressive and technical ones did become uncomfortable. If you have a good rotation of high-waisted yoga pants, they’re a great option to use without buying maternity-specific apparel. 

The Athleta Salutation Stash tights are one particular pair of athletic tights that continue to fit comfortably in my regular size, even as I approach the third trimester. The wide and soft waistband is completely unrestrictive while still offering gentle support. The nylon and lycra fabric is ultra soft and lightweight and wicks well, whether in the yoga studio or on a hot and sunny hike.

These tights have some light compression but aren’t as compressive or functional for high-impact running, and I wouldn’t recommend bushwhacking in them, or you’ll likely end up with some snags. But they worked very well for higher-intensity, fast-paced hikes, circuit and strength workouts, and yoga (that’s what they’re made for, after all). The dual-side stash pockets are a nice addition, and I love that they’ll still fit and remain in rotation long after I say goodbye to pregnancy. 


It’s worth noting that for runs in cooler temps, my Athleta Rainier tights (our best overall winner for women’s winter running tights) have continued to fit well into the second trimester, along with the Ridge Crowley Compression Merino tights. Because they are both more structured in the waistband, that may change in the third trimester, but still, it’s nice to have the option of technical cold-weather running tights for now.


LOW-WAISTED JOGGER HIKING PANTS

A low-waisted pair of hiking pants can also be a great option during pregnancy. If the pants hit below the bump without being too tight, then they can work well even as your body changes. I found that a handful of the jogger-style pants in my closet have continued to work throughout pregnancy, even though they are not made for maternity. 

The Haven Joggers are made with a durable Tencel, Nylon, and Spandex-blended fabric that feels like what you’d expect from a beefy pair of hiking pants but in a relaxed jogger fit that has an elastic waistband rather than a snap or button. This means they function well on the trail while the stretchy waistband leaves room for your belly to grow. I continue to wear mine low and below the bump for hikes and backpacking trips. They’re abrasion resistant, have UPF 50+ sun protection, and have great pockets that fit a phone or snacks securely.


Paddling In Kuhl Sun Shirt During Second Trimester

SUN HOODY

I live in the mountains, and most of my days outside are spent in the high alpine with lots of sun exposure. That means I’m almost always wearing some sort of sun protection when I’m out, and that’s especially important when you’re pregnant. Many of my sun hoodies fit in the early months of my pregnancy, but some of my go-tos lacked the coverage to totally cover my belly as it grew. As far as I’ve found, a maternity-specific sun hoody does not exist, but I think I found one that’s even better, given that I wore it before pregnancy and will continue to afterward.

I’ll be honest: When I initially tried this sun hoody, the tie at the bottom of the torso wasn’t my favorite. Now, I’ve come to greatly appreciate it. This sun hoody is made with a UPF 50+ material that breathes and wicks moisture very well; I wore it on hot summer hikes in Arizona and backpacking trips in Colorado. The tie at the bottom is meant to be a cute style detail, but I’ve found that the fit of this shirt paired with that tie makes this transition seamlessly as my belly gets bigger. It doesn’t ride up even with a backpack on and offers all the coverage I need for long days out in the sun.


SUPPORTIVE YET COMFORTABLE SPORTS BRA

Your boobs only get bigger and more tender during pregnancy, which means that having a good sports bra is crucial. Being pregnant can also make breathing more challenging since everything in your torso is now competing for space. This means that a supportive but not overly compressive or cumbersome sports bra is ideal. If it lacks support, you’ll be uncomfortable while you’re active and moving. But if it’s too snug, structured, or compressive, that can also lead to discomfort, making breathing tougher. Read about our favorite AA to D cup and D+ cup sports bras. 

SMARTWOOL INTRAKNIT RACERBACK AND STRAPPY BRAS

These Smartwool sports bras have been my go-tos for just about everything during pregnancy, from backpacking to mountain biking. They’re comfortable, wick well, and fend off odor, all while offering moderate support without being overly restrictive. 

I opt for a slightly more supportive bra, like the Oiselle Flyout, for higher-impact activities like running. 


RUNNING SHORTS

Running shorts have been one of the easier pieces of gear to keep in rotation during pregnancy. For the first several months, I could continue wearing some of my favorites. The low yet soft and comfortable waistband on the Stio Second Light shorts has remained comfortable and functional into the end of the second trimester, given that I can wear them comfortably below my bump.

Backpacking Second Trimester Stio Shorts

I’ve worn these on jogs and hikes, plus multiple backpacking trips while pregnant, and they’ve remained wonderfully comfortable. A big bonus for these shorts is how breathable and quick-drying they are, including the liner. I’ll spare any details, but that’s an especially nice feature during pregnancy.

If you’re looking for shorts that offer more support for your belly while you run, a fitted compression short like the Oiselle Pocket Joggers work well (as long as they’re not too constricting on your stomach–Oiselle often runs small for folks). High-waisted biker-style or yoga shorts can also get the job done.

CYCLING SHORTS

Thankfully, cycling shorts are meant to be stretchy, and many of my chamois and shorts have continued to fit. I can’t say the same about all my mountain biking baggy shorts. Opt for shorts that are compressive but not overly so. I found that into the second trimester, my favorite cycling bibs simply became too constricting to wear, and I had to retire them. But my less compressive high-waisted cycling shorts continue to work just fine. As for baggies, most of them no longer fit, though my Shredly MTB shorts and Rapha Trail Fast & Light shorts made it the longest, thanks to their stretchy, comfortable waistbands.


SKORTS

For ladies who like the style, a skort can also make a great option for hikes and runs while pregnant. Like other bottoms, opting for one with a wide and stretchy waistband (like the Girlfriend Collective Sport Skort) will be the most comfortable and will hopefully fit for longer during pregnancy.


MATERNITY TANK TOPS OR LONG INSEAM TANKS

Maternity tank tops, like the Beyond Yoga Bases Covered maternity tank, leave plenty of room for your bump while having good length and full coverage. This is especially helpful if you’ve outgrown your regular tanks or summer activewear. If you have long inseam tanks in rotation, these will often work without having to buy a maternity-specific one. If you’re hiking or backpacking and wearing a pack, it’s crucial to have a top that offers coverage and doesn’t ride up so your pack isn’t rubbing uncomfortably on your bare skin.


BASE LAYERS WITH COMFORT AND COVERAGE

Like tank tops, it’s good to find base layers that offer full coverage. The combo of a long inseam in the shirt and high-waisted base layer pants is often best for full belly coverage. My favorite base layer top during pregnancy was the Kari Traa Smekker. It has a longer fit that offered coverage throughout pregnancy and kept me and my belly warm and comfortable (all without having to size up). 

For bottoms, again, high-waisted and wide waistbands were the name of the game; my ages-old Patagonia Capilene Midweight bottoms have a somewhat loose and super comfortable fit that still manage to fit while pregnant.


COMPRESSION SOCKS

While this may not be necessary for all pregnant ladies, a pair of compression socks can work wonders for hiking and other outdoor activities while pregnant. One of the many fun things that comes along with pregnancy is a tendency for swelling feet and legs. Compression socks can do a lot to help mitigate this and keep your feet happy.

COMFORTABLE, SUPPORTIVE SHOES

There are all sorts of odd things happening in your body when you're pregnant, and among that list is loose ligaments, swelling feet (and even foot growth), and back pain. A good pair of shoes won’t make this go away, unfortunately, but it definitely helps. 

I found that opting for wide, high-cushion trail runners worked best for me, and after the first couple months of pregnancy, I had to go at least a half-size up to keep my feet happy. Winner of our Best Trail Running Shoe for Long Distances, the Altra Lone Peaks (in a full size up) worked well in early pregnancy for me. Then I switched to the high cushion Arc’teryx Norvan LD 3 (my regular size worked since these run quite big) to get me through most of the second and third trimesters. 

When I was at home after biking, backpacking, or hiking, I wore my Oofos Ooahh slides – which won our Best Overall Recovery Shoe for Runners–around the house to help my feet and back recover after activity.

CLOTHING FOR WINTER SPORTS

For winter running, I’ve transitioned many of my leggings and base layer shirts to work throughout pregnancy. Options for technical winter active apparel for pregnant bodies are very slim, so sometimes it’s best to work with what you have. I opt for my warmest leggings or yoga pants that still fit, and pair them with longer-fitting wool base layers and jackets that fit on the larger side. Many technical jackets have dual front zippers, primarily intended for use with a climbing harness. It turns out those zippers can be helpful for pregnant bellies, too. 

Before I discuss ski gear, it’s worth noting that most doctors advise against downhill skiing or ski touring when pregnant. Always talk with your doctor first, know your own abilities (don’t learn to ski or try to challenge yourself when you’re pregnant!), and listen to your body. Some pregnant folks (myself included) feel comfortable enough to make some mellow turns on snow, even with a bun in the oven, though that doesn’t mean it’s for everyone. If you do decide to click into skis, here are some tips to stay comfortable, warm, and dry. 

It’s safe to say that no one is making maternity ski gear, given that alpine skiing is on the blacklist for activities for most pregnant people. If you want to take it easy, play it safe, and still make some turns, reach first for bibs instead of ski pants. They’ll stay up more easily and the side zips can be adjusted to accommodate your belly. When it comes to jackets, I’ve found that my anorak worked well. Again, side zip for the win – I can unzip a little if necessary without exposing the front of my belly to the elements. But if you want to make other jackets in your closet work, something like the MakeMyBellyFit Universal Jacket Extender can come in incredibly handy and works with just about any jacket that has a regular front zipper.

Pro tip for pregnant skiers: Now is not the time to splurge on new boots or a bootfitter. Turns out feet change a lot during pregnancy, often growing a half size or more. Sometimes they go back to their old size and shape postpartum, but sometimes, they don’t. Avoid new boot purchases or major modifications until you’re back to normal after giving birth and can assess how much your feet have permanently changed.


OTHER GEAR THAT HELPS DURING PREGNANCY

These are a few pieces of gear that can be especially helpful when pregnant, plus some tips for modifying gear.

KULA CLOTH

It’s no secret that you end up peeing a whole lot more often when you’re pregnant. Many backpackers and hikers swear by these pee clothes even if they aren’t pregnant. I did not become a convert until I was expecting and found myself pulling off the trail all the time for pee breaks. 

An extra tip for expecting mamas who want to keep backpacking: lighten the load and loosen the waistband. It’s generally fine to keep backpacking well into pregnancy (as long as you clear it with your doctor). But it’s a good time to hone your packing skills and practice a little of the ultralight ethos. I kept my pack at 20 pounds or less once I was into the second trimester and left my hip belt on the looser side so as not to constrict or pinch my belly.

BELLY BAND

Belly bands can be helpful later in pregnancy to help support your belly and back as your baby gets heavier. Your doctor may even recommend one, depending on your specific pregnancy situation. The light and stretchy Gabrialla Maternity Support Band and JoJo Maman Bebe Support Workout Bump Band are recommended by Runner’s World.
