Best Women’s Hiking Underwear that Stay Put & Wick Sweat

Here are the best women’s hiking underwear that don't chafe and that efficiently wick moisture when you’re active outdoors.

On Bearfoot Theory, we mostly talk about all of the fun stuff: incredible hiking and backpacking routes, ways to save up for that big trip, and how to become a better skier, just to name a few. Yet there’s also the basics and the nitty-gritty details that enable us to get outside and be comfortable that aren’t always as exciting. Enter: women’s hiking underwear.

A bad pair of women’s hiking underwear can really put a damper on things. They can be uncomfortable, distracting, and at times, not the healthiest choice for your body. Plus, who wants panty lines?

The best outdoor underwear does the opposite and ironically, you’re likely to forget that you’re wearing them. That’s the kind we like to buy.

If you’re in the market for a new pair or want to upgrade your closet, we compiled a list of our favorite underwear for hiking and other active pursuits to help you out.

Here’s the best women’s hiking underwear that stay put and wick sweat as well as what kind of underwear to avoid.

The Worst Kind of Fabric for Women’s Hiking Underwear

This un-coveted award goes to cotton. Similar to other outdoor, travel or athletic clothing, cotton is never a good fabric to wear when you’re staying active. The reason for this is because you’re likely getting sweaty or even just raising your body temp enough to create some moisture, and cotton is not a breathable fabric. The best outdoor underwear is moisture-wicking and prevents chafing when you’re breaking a sweat.

On top of that, cotton underwear will absorb and trap moisture and odors, which isn’t comfortable, and can lose its shape over time – which can become a serious problem if you are backpacking. While they are comfortable for lounging around at home, they aren’t suitable for the outdoor enthusiast at play; trust us on this one.

The Best Women’s Hiking Underwear

lululemon InvisiWear Mid-Rise Boyshort Underwear

As someone who hikes and lives an active lifestyle, I need my underwear to stay in place so I’m not constantly picking out wedgies. I also hate panty lines, since I almost exclusively wear leggings. I was so happy to discover the lululemon InvisiWear Mid-Rise Boyshorts, since they check both of these boxes.

These underwear are lightweight and have a barely-there feel. The edges are seamless, making them truly invisible under leggings.

I wouldn’t say these fit like a traditional boyshort however. The coverage is more like what I would call a hipster. They cover your whole butt, but they don’t go down over your leg. For reference, I weigh 140 pounds and wear size 8 pants, and the medium in these underwear fit me well.

These also come in a 3-pack which I’ll be picking up now that I know how much I like them.

ExOfficio Sports Mesh Underwear

This brand sells versatile clothing designed to keep the traveler comfy and active. So it’s not surprising that their women’s hiking underwear also gets the job done. We love their Give-N-Go Sports Mesh underwear because they are lightweight, flat-seamed, breathable, and high-performing; meaning it can keep up whether you’re roaming the streets of a foreign city or going for a trail run at home. Depending on what pants you wear, panty lines might be visible, especially in leggings. We have also found that they stretch out over time, but they should last you for plenty of adventures.

Patagonia Women’s Active Hipster Underwear

If you prefer more coverage, you’ll be a fan of Patagonia’s Active Hipster. The rise is higher, although still technically a low-rise, and it has flat-lying seams that won’t budge or roll over as you move. The fabric is a blend of recycled jersey spandex, polyester, and nylon that has antimicrobial properties. Most importantly, it’s breathable, so you stay fresh and dry all the time. They are also available in briefs.

Boody Women’s Hipster Bikini

Besides having a great name, Boody makes eco-friendly bottoms that are some of the best women’s hiking underwear — and the most budget-friendly pair on this list. They make briefs, bikinis, thongs, and boy short styles with breathable, thermo-regulating, and even hypoallergenic material. Grab a pair in one of their neutral colors for a no-worries day outdoors.

Smartwool Women’s Merino Seamless Underwear

Smartwool’s seamless merino underwear is just as effective at regulating your body temperature as their base layer tops and bottoms if not more, thanks to their Core Spun technology that blends merino with nylon fibers. In short, it has a next-to-nothing feel with a comfortable fit that won’t ride up, bunch, or show panty lines. This pair is a little more pricey but definitely worth the investment. Note that many women agree these run a little small, so you may want to size up.

ExOfficio Modern Travel Bikini Briefs

Another nylon favorite from ExOfficio is the Modern Travel Bikini Brief. In addition to being lightweight and breathable they are seamless, so no panty lines. Plus, the mesh side panels help you stay fresh and are form-fitting underneath your clothes. They run a little small but I find that they do stretch out a little in between washes.

Icebreaker Siren Hipkini

Icebreaker is a New Zealand company known for its high-quality merino wool outdoor apparel. They make a bikini and a sport hipkini style of underwear that gets rave reviews. We love the hipkini for its full coverage and awesome odor control capabilities.

REI Co-op Active Hipster Underwear

REI Co-op has their own new line of active underwear for women. They’re made from stretchy polyester mesh and they are designed to be moisture-wicking, quick-drying, and antimicrobial so they’re perfect for long, hot days on the trail. We noticed that they do run a little small so you may want to size up or go with the brief version for a little more coverage.
