The 5 Best Hiking Underwear for Women

When going for a hike, the clothing you wear underneath can be just as important as the clothing you wear on the outside. I didn’t even realize that there are special hiking underwear for women until a few years ago, but when I tried them for the first time, it was a game changer.

The underwear made especially for hikers and other active women keep you comfortable and dry. It is so annoying to have to keep pulling your underwear into place or having sweaty spots where you do not want them. Certain poorly designed underwear can even cause chafing when performing a rigorous activity like hiking.

Great hiking underwear prevents all of these awful issues. When searching for your perfect hiking underwear, you may want to look for a few key features.

What to Look For When Shopping:

  • Moisture wicking fabrics: This keeps sweat from building up exactly where you do not want it to. It also makes them quick-drying for when you do get a little wet or sweaty. Keeping your underwear dry keeps out smells and some even have antimicrobial treatments to further help with stench.
  • Seamless or flatlock seams: Bulky seams can cause chafing, which is extremely unwanted. Most women’s active underwear come in seamless options or flat lock seams that don’t stick out. Making wiry threads rubbing on your skin impossible.
  • Breathability: Your underwear need to be breathable so you don’t get too hot and sticky while doing tough activities. Hiking underwear are designed with materials in the right areas to increase airflow that will keep you cool.
  • Extra stretchy fabrics: You want ultimate mobility when hiking, climbing, biking, or whatever other outdoor activity you enjoy. Especially with underwear that is so close to your skin and located right at the hips and legs where you need the most movement. Fabrics like lycra and spandex are a must.
  • What fit you prefer: Hiking underwear come in boyshort, cheeky, bikini, and other shapes that may affect your personal comfort. They also make mid-rise and low-rise options. Everybody prefers their own shape and knows what fits best on themselves.

With those considerations in mind, here is a list of some of the best hiking underwear for women.

Sprite Hot Pants

The Sprite Hot Pants is another boy short option with a unique spin. These are extra durable and soft on the skin with Icebreaker’s special fabric that is meant for activities, such as hiking. They also have features that keep these in place during tough maneuvers.

Details & Features:

  • Pice: $27 
  • Fize sizes: XS, S, M, L, XL

  • Comes in boxer brief option
  • Offset seams
  • Mobile stabilizer
  • Low rise
  • Naturally antimicrobial

Icebreaker’s special material is merino wool core spun fabric. Merino wool is made of nylon fibers wrapped in wool. This keeps the fabric of these underwear extra soft while making it even stronger than regular nylon. Lycra spandex is added to the fabric for extra mobility.

If you want maximum coverage, these come in a boxer brief option as well. Although these already have a lot of coverage and support, the boxer briefs go the extra mile. The boxer briefs would be great for hikes on days when it is a little cooler outside and you want some extra warmth on your legs.

Mobile stabilizer is a design at the leg openings that keep these where they should be. The leg hem has more structure than the rest of the underwear. The added structure keeps these from rolling up or sliding. This may be a little uncomfortable though if you are more curvy.

Another nice thing about merino wool is that it is naturally antimicrobial. Bacteria does not grow on it and therefore will not cause odor. This also means that there is no treatment that can be washed away after many washes.

Under Armour Pure Stretch Sheer Cheeky

For those of you that like a little less coverage than a boy short or bikini, try these cheekies. These are super comfy with the maximum amount of stretch and great breathability. The sheer cheeky is durable enough for anything from yoga to hard climbs.

Details & Features:

  • Price: $20
  • Size: One size fits all
  • Colors: Black and White
  • Fabric: 76% Nylon and 24% Elastane
  • Comes in thong option
  • Breathable mesh
  • Flat lock seams
  • 4-way stretch
  • Antimicrobial treatment
  • Cotton gusset

You won’t ever have to worry about pinching or chafing with these incredibly stretchy underwear. They are so stretchy that they only have one size for everybody. A quarter of these are made of elastane and the flatlock seams won’t rub on you. 4-way stretch makes every movement smooth.

All of the fabric in these are made of breathable mesh, even the waistband and leg bands. You can hike in hot days without getting too hot. However, there is a cotton crotch gusset to give extra protection that may cut off ventilation where you may want it. Some may want the extra protection though.

Stretchy mesh is amazing, but doesn’t prevent moisture. With moisture-wicking fabrics, like nylon, your skin will stay dry. Antimicrobial treatments keep bacteria from building up in sweat and causing odor. Keeping you dry and fresh for longer.

These come in a thong option as well if you prefer the least amount of coverage. They have all the same great benefits, but can be worn invisibly under other tight clothing. They are still breathable, stretchy, very durable with flat lock seams.
