The Best Hiking Underwear for Men

(Last Updated On: October 23, 2018)

Underwear is the unsung hero of hiking clothes. This vital piece of clothing helps protect our most delicate parts, but many outdoor enthusiasts don’t pay much attention to them while gearing up for a trip. Hikers will go above and beyond to get the best hiking gear they can afford, only to settle for cotton briefs when it’s time to buy hiking underwear.

But cotton is a terrible fabric if you are adventuring outdoors, especially when there is a high chance of getting sweaty or wet. Cotton has a high affinity for moisture, and it will stay wet if you are unfortunate enough to get it wet. Dampness not only causes itching and discomfort for the boys, but it can also breed microbes and odor, two things you don’t want if you are short of supplies or far away from civilization.

In short, your choice of hiking underwear can make or break your hiking experience, and that’s why you need to buy quality. Whether you are going for a day trip, a weekend hike through the National Park near you, or a three-month long expedition in the jungles of the Amazon, nothing beats a great pair of comfortable underwear that is breathable, fast drying, anti-microbial, and durable.

If you are shopping for hiking underwear, don’t settle for less. Your hiking experience will be greatly curtailed if your underwear keeps getting bunched up, chafes your skin, slips down, retains moisture, lacks support or provides too much support, is smelly or itchy, or gets torn halfway through your trip.

The fact that your underwear is out of public view doesn’t mean you should dress shabbily down there. Your comfort is paramount, and you owe yourself a reasonable amount of ease, even though the outdoors can be quite unforgiving.

In this article, we will look at the top ten hiking underwear you should be rocking in 2018. It’s important that you don’t make price your primary goal when buying travel underwear. What you should look for is value. Plain and simple, cotton can be dirt cheap, but it offers less comfort when you are in the outdoors.

If you don’t want your legs to be chafed or develop a nasty odor down there, then it’s better to invest in top quality undergarments made from Merino wool or synthetic materials such as nylon or Lycra. The price for a pair of boxers on this list may seem outrageous, but the comfort and breathability they offer is well worth the price tag.

What to look for when you are buying hiking underwear

First, let’s examine the important factors to consider before buying hiking underwear.

Material

The main reason why you would want to splurge on high-quality undergarments is for maximum comfort, and one of the most important factors for comfort is material.

The ideal hiking underwear should be made of fabric that doesn’t create constant abrasion with the skin, thus reducing friction, chafing, or rubbing after prolonged use.

The material should be breathable, quick-drying, anti-microbial, and moisture-wicking. Fabrics made from Merino wool and synthetic fiber such as nylon, lycra, or polyester offer these qualities. Most makers of premium hiking underwear also add some elastic fiber like Elastane or Spandex to their underwear to give it some degree of flexibility.

Elasticity ensures that the garment conforms to your body and stretches whenever you move, rather than chafe your skin, thereby increasing comfort.

Should you buy Merino wool or synthetic underwear? It depends.

Merino wool is a natural fiber with several impressive characteristics. The fabric is naturally antimicrobial, soft and tender on the skin, offers warmth even when wet, more breathable, and can wick moisture away from the skin, a feature that makes it perfectly suited for wet conditions. However, Merino wool is not durable and may quickly wear and tear under heavy use. Plus, it’s more expensive.

On the other hand, synthetic underwear such as nylon, polyester, lycra, polypropylene or a combination of these are more durable, last longer, and dry faster. They are also more affordable compared to Merino wool. In terms of comfort, Merino wool underwear leads the pack, but they might not be durable enough to withstand heavy use.

Durability/Construction

It makes no economic sense to cough out top dollar for luxury underwear if they can’t stand the rigors of the outdoors, and this is why durability and construction are important. Many experts and users swear by the comfort which flat-lock seams provide. Flatlock seams have a smaller surface area, which reduces contact and friction with your skin, thus reducing the risk of chafing and bruising.

When you are outdoors, washing your underwear with a mechanical washer might not be possible, and you may have to wash manually. Synthetic underwear offers more durability and will hold their own even after extensive and rough use. Merino wool, on the other hand, needs special fabric care and may fall apart before synthetics.

Antimicrobial Protection

Hiking underwear that is antimicrobial will save you from a lot of itchiness, odor and keep you and your boys happy for the duration of your trip. If you will be going out for several days and packing light is the best option, antimicrobial underwear keeps you fresher longer, especially because you will get sweaty and grimy, prime conditions for germs to thrive.

Merino wool is naturally antimicrobial, and this makes it comfortable to wear for longer without any foul smell. Synthetics can also be treated with antimicrobials, but these will wear off over time with regular washes. Meanwhile, polypropylene can quickly get smelly when damp, so you might want to steer clear of the fabric if you will be traveling during the wet season.

Style

While there are several styles of underwear for men, the ideal hiking undergarments are boxer briefs, as per several experts. Boxer briefs are tight fitting, making them efficient at moving sweat away from the skin surface to the outer layer of the fabric. This feature might seem unimportant, but it can help keep your delicates dry, fresh, and comfortable. Additionally, the tight fit means chaffing is greatly reduced.

Drying Time

When you are on the trail and have only two pairs of underwear, drying time becomes an important issue. With the right set of hiking underwear, you can make do with two pairs if the fabric will dry fast enough before the other pair needs washing. Plus, faster drying time means you can wear the underwear while wet and it will still offer some level of comfort. Synthetic fabrics dry faster compared to Merino wool, but both can still be worn with some level of comfort while wet. Drying time is an important factor to consider if you are traveling through tropical environments where humidity is higher, or rain is unpredictable.

Now, let’s check out the top ten hiking underwear for men.

Smartwool NTS Micro 150 Boxer Brief

Material: 100 Percent Merino Wool

At $45, the Smartwool NTS Micro 150 Boxer Brief is one of the most expensive brands of premium hiking underwear, but it delivers with excellence.

With a perfect fit and soft waistband for maximum comfort, this undergarment offers superior design and construction to keep you fresh and dry. It is made from 100 percent Merino wool, making it super soft and gentle on the skin.

Flatlocked seams help to reduce chafing in all the delicate places where your skin might come in contact with the garment. One of its innovative designs is the sideways waistband stitch which effectively eliminates any friction with your backpack.

Because it is made of Merino wool, Smartwool NTS Micro 150 Boxer Brief offers exceptional anti-odor protection compared to synthetic brands with special chemical coatings to reduce microbial growth. The only downside is that these boxer briefs are not as durable as synthetics and don’t dry as quickly.

Also, the price tag is hefty for a single pair of shorts. It’s not like its self-washing or will last longer than sturdier man-made fabrics. But if you can afford it, it’s a great fit that makes for delightful experiences on the trail.

Which Is the Best?

Most of the underwear on this list have impressive characteristics. While the Merino underwear offers higher comfort, breathability, and antimicrobial resistance, the synthetic brands provide higher durability and lower dry time.

Comfort is a general feature of all, but different construction processes and quality of materials has a huge impact on how dry and fresh you feel down there after wearing your hiking underwear for a long period.

REI Boxer Briefs

A true contender for the title of best budget underwear out there, the REI Boxer Briefs are a no-frills, no-fuss pair of undies that offer great value for money despite a few notable shortcomings. Using an 87% polyester and 13% spandex blend, these briefs are amply stretchy and durable but lack the naturally antimicrobial qualities of their pricier, merino-based competitors. One aspect that may appeal to many is the more regular, classic fit of this product — if you’re not a fan of compression briefs, the slightly looser feel of REI’s Boxer Briefs might just win them your vote.

Otherwise, these boxers do everything reasonably well without quite scaling to the heights of more expensive models in terms of performance. In a nutshell: a solid bet for those on a budget, but a compromise for those who want the best their money can buy.

Pros

  • Reasonably priced
  • Wick well
  • Breathable
  • Comfortable
  • Made with durable materials (92% polyester, 8% Spandex)

Cons

  • Material doesn’t contain antimicrobial properties
  • Inseam a little short (4.75 inches)

Under Armour Compression 6” Shorts

For those not too fussed about the naturally antimicrobial properties and super-soft feel of merino, the Under Armour Compression 6” Shorts pose an attractive synthetic alternative. Using 90% polyester and 10% elastane, these ultralight briefs are high-wicking, breathable, durable, offer plenty of stretch, and compress better than many other items in our review. They also use flatlock seams and a 6” inseam that together make chafing far less likely than with regular underwear or standard length briefs that fail to cover that chafe-prone hotspot at the midpoint of the inner thighs.

The downsides? Well, although these briefs use an anti-odor treatment that works perfectly well1 on the first few outings, its efficiency is sure to decline after 10 or so washes. Also, in an effort to keep the design as smooth and sleek as possible, Under Armour have chosen to omit a functional fly — something that may be a deal-breaker for some would-be buyers.

Pros

  • Excellent wicking capacity
  • Compression style ideal for hiking
  • UPF 30+ sun protection
  • 6” inseam
  • Breathable
  • Anti-odor treatment effective while it lasts

Cons

  • Not naturally antimicrobial
  • No fly

Helly Hansen HH Warm Boxers

First things first: the name of these boxers is something of a misnomer. While the HH Warm are made with thicker materials and thus run a fraction warmer than many other items in our review, these undies also hold their own in toastier temps and do a good job of keeping things fresh and sweat-free down below. These boxers also have a number of other factors working in their favor, most notably a performance-minded blend of antimicrobial merino, high-wicking proprietary LIFA, and a little more stretch than many other merino briefs with lower elastane content.

But it isn’t all good news… For those with larger leg muscles, the relatively narrow leg opening on these boxers may make things a little too tight for comfort; and, for those who prefer to do their peeing without the inconvenience of undoing their belt or the top closure on their pants, the lack of a fly opening will maybe exclude this otherwise functional pair of briefs as a viable option.

TIP: If these boxers make it onto your shopping list, beware that the sizing runs a little small and shoot at least one size up from what you’d take in your normal underwear.

Pros

  • Naturally antimicrobial properties
  • HH’s LIFA hydrophobic technology fabric provide excellent moisture wicking
  • Nice blend of merino and synthetic fabrics gives the best of both worlds
  • Flatlock seams
  • Comfortable

Cons

  • No fly
  • Very tight fit in thighs for larger-muscled users

Saxx Kinetic Boxer Briefs

While not marketed to hikers quite so categorically as other items in our review, the Saxx Kinetic Briefs do pretty much everything a hiker could ask of their underwear. Using an 85% nylon and 15% spandex blend, these briefs are both more durable and stretchier than many of the merino-based products in our review, and as such are cut out for the rough and tumble and lunge-like moves many of us are more likely to be cutting on more demanding hikes. Other performance-oriented features that earn these briefs their place on our list include flatlock seams, a semi-compression fit, antimicrobial treatment, and excellent breathability.

Sadly, these briefs aren’t naturally antimicrobial so will lose some of their odor-resistance over time, but otherwise they’re a good bet for those who don’t necessarily want to buy a pair of briefs that are especially suitable for the great outdoors while lacking the more casual, stylish, relaxed look and feel of briefs made for everyday use.

Pros

  • Very stretchy owing to 15% spandex content
  • High-wicking fabric
  • Flatlock seams
  • Antimicrobial treatment relatively long-lasting
  • Semi-compression fit

Cons

  • No fly opening
  • Not naturally antimicrobial

Smartwool PhD Seamless Boxer Briefs

Made with 72% merino wool, 22% nylon, and 6% elastane, the Smartwool PhD Seamless Boxer Briefs tick all the boxes that need ticked on the material front. Not only does the high merino content make them soft, comfortable, and naturally antimicrobial, but the additional nylon adds durability and strength while the elastane gives them enough flex and stretch to cope with whatever shapes you might happen to be cutting while out on the trail.

Beyond the materials used in these briefs, there’s a lot more to love. They’re high-wicking, breathable, dry very fast and use, as the name suggests, a seamless design that’s ideal for those prone to chafing in or around the underparts.

And the downsides? Other than their slightly hefty price tag, we’ve been unable to turn up a single one!

Pros

  • 72% merino wool
  • Nicely stretchy
  • More durable than most merino-only garments
  • Wick well
  • Breathable
  • Very comfortable

Cons

  • Kinda pricey

And The winner is…..

Conclusion

Underwear should be an important part of your gear when preparing for hikes. (Read more about what you should wear here!) While there are many cheap cotton boxer-briefs on the market, you will do well to invest in one or two pairs of quality hiking underwear.
