Best Hiking Underwear for Men
Designed for hardcore adventurists and heavy exercise, the SAXX Hyperdrive is both supportive and comfortable. If you’re used to sweaty thighs and chafing after you’ve been out hiking for a day, it might be time to upgrade to the Hyperdrive underwear. These are essential to a men’s hiking outfit.
Features of the SAXX brand include Flat Out Seams, meaning that the stitching has been reversed to put the flatter and softer side of the seam against your body. This helps prevent itching and discomfort, particularly when you’re exercising and moving around.
Everything is kept in its place with the Ballpark Pouch design, which ends any skin-on-skin friction you might have been dealing with in the past. Plus, the moisture-wicking material keeps you cool and dry even when hiking in hot weather.

Hiking Underwear Terms
- Antimicrobial: The property that prevents the spread of bacteria while hiking.
- Fly Opening: Some men like to have a fly in their underwear, so it’s easier to pee in the backcountry.
- Merino Wool: A common component of hiking underwear.
- Odor Resistant: Hiking means you’re going to get sweaty, so it’s important to pick clothing items that won’t stink. Merino wool is a natural odor-resistant material and won’t break down over time.
- Moisture Wicking: Properties that get rid of moisture when sweating.
- Tagless Underwear: Many hiking underwear options are tagless so you don’t have something itchy always against your skin. It’s a great aspect to look for when shopping. Of course, if you prefer, you can always cut the tags off yourself.
- Flatlock seams: Wide seams that won’t cut into you or scratch you are important. The best ones are flat and wide seams (in other words, “flatlock seams.”
Hiking Underwear for Women’s Styles
Women’s briefs offer solid all-around coverage and sit above the hips. If you want full coverage, go for a pair of women’s briefs.
Bikini-style underwear is just what you may imagine – like a bikini! They provide coverage in the back and front, just not as much as the briefs. They often have a lower waistline and less rear coverage.
Women’s boxer briefs have a longer cut on the leg that extends to the top of the thigh. They are incredibly comfortable and reduce inner thigh chaffing with the extended cut.
Thongs provide the least amount of coverage but are lightweight and very small. Because of this, they are quick drying.
Hiking Underwear for Men’s Styles
The loosest fit for men is boxers. Boxers provide a loose fit while hiking, which can often lead to scrunching, which isn’t comfortable. I would strongly recommend against ever hiking in boxers.
Good comfortable support that sits snug against the legs. They are shorter than boxers and boxer briefs, so they may cause chaffing.
Boxer briefs blend the best of boxers and briefs into one product! They are longer than traditional briefs, providing more coverage while offering a snug feel.
What to Look for When Buying Hiking Underwear
The material that goes into a good pair of hiking underwear is important. You’re engaging in an outdoor activity that is oftentimes very strenuous. That means sweat and discomfort can build up if you don’t have the proper materials. Hiking in a lacy thong or undergarments that are too tight will only worsen your day. This could even mean redness, swollenness, or chaffing – which are never good signs.
You’ll want to invest in breathable, moisture-wicking, and quick-drying underwear. Good hiking underwear is often made out of merino wool and nylon or lycra, and they are words you’ll see mentioned a lot throughout this article.
Cotton, though inexpensive, does not dry quickly and can cause chaffing. Products made with lycra are ultralight and breathable, have anti-odor technology, and reduce chafing. They are also easy to care for and wash if you are in the backcountry.
Cut and Style
Pay attention to the cut and style of the underwear for hiking that you buy. There are many different offerings for both men and women, and it’s all up to you and what is comfortable.
It’s important to remember that you are hiking and engaging in physical activity and should pick a style that will fit nicely underneath hiking pants and won’t ride up. For men, different options include briefs, boxer briefs, and boxers. For women, different styles typically include thongs, hipsters, or bikini briefs. Many of the hiking underwear included here come in many different styles.
When you’re hiking, you’re probably going to sweat down there. Even more so than you normally would. It’s important to find hiking underwear that is antimicrobial so that you keep fresher longer.
For most of these products listed, you’ll pay much more for underwear than you would regular underwear. $20-$30 is the average price to pay for hiking underwear. While it may sound expensive, it’s important to note that hiking underwear is made with durability in mind.
They are designed to hold up well to the natural elements and keep you comfortable for days on the trail. Things like Flatlock seams to reduce chaffing and antimicrobial are built for hiking.
When choosing hiking underwear for men and women, look for a fit that is snug but not too tight. Underwear for hiking should conform to your body but not cause discomfort because it is too tight. If the hiking underwear is too large, it can cause bunching and rubbing. Pay attention to the fit guides when purchasing hiking underwear.
If you plan on making multi-day hiking trips, it’s important to pay attention to the care instructions for your hiking underwear. You won’t have access to a washer and dryer and should be prepared to wash your clothes by hand. This is where hiking underwear with quick-dry capabilities comes in handy.
