Best Hiking Underwear – Overview
ExOfficio Men’s Give-N-Go Boxer Brief
- These breathable men's boxer briefs are great for traveling by plane, hiking, exploring cities, or any time comfort, freshness, and moisture wicking are your top concerns
The ExOfficio Men’s Give-N-Go Boxer Brief features a special diamond-knit mesh fabric construction, which gives the underwear a comfortable, snug fit without being overly tight or constricting. The synthetic fabric is also moisture-wicking and well-equipped of dealing with sweat and condensation. These boxer briefs by ExOfficio feature the brand’s proprietary Silvadur antimicrobial treatment. This odor-eliminating antimicrobial treatment ensures the fabric is less prone to retaining unwanted odors. Allowing you to not just feel fresh, but also smell fresh. Even after long backcountry hikes.
Ultralight and highly-rated
Another perk of the ExOfficio Men’s Give-N-Go Boxer Brief is that the style comes with an elastic waistband that retains its shape, even with daily wear. ExOfficio Men’s Give-N-Go Boxer Briefs are also ultralight at just 2.24 ounces, meaning it won’t weigh down a backpack and helps you save on packing weight for multi-day trips.
The ExOfficio Give-N-Go Boxer is highly-rated by other hikers, with thousands of 5-star reviews on Amazon confirming its outstanding performance. Hikers praise it as the perfect pair of hiking underwear due to their quick-drying abilities, comfort, and odor-resistant properties. One reviewer confirms the style is capable of a few days wear without retaining unwanted odors, serving as a testimony that the briefs do live up to and exceed expectations.
Also good to know: If you like the sound of ExOfficio’s high-quality underwear but are not a fan of this particular boxer briefs style, there are other options available! The ExOfficio Give-N-Go is also ready to order via Amazon in other fits, including briefs, boxers, and bikini-style silhouettes.
- Not very insulating
- Not the most durable
Icebreaker Merino Men’s Anatomica Zone Long Boxers
- Cool-Lite fabric for faster wicking
The Anatomica Zone Long Boxers by Icebreaker feature the same fantastic fit and comfort as the original Anataomic briefs, with the bonus of extra ventilation. The lightweight, stretchy, and breathable boxers are made of jersey Cool-Lite fabric. This fabric features corespun fibers: nylon threads wrapped in merino wool. The combination of nylon and merino creates a next-to-skin softness, making this a superb choice as a hiking base layer.
The fabric also contains lycra, for added stretch and mobility. To boost its breathability even further, Icebreaker added panels of corespun eyelet mesh in key areas of the boxers. These clever mesh panels promote airflow where it matters most, keeping you dry and fresh.
The Icebreaker Merino Men’s Anatomica Zone Long Boxers are also designed for chafe-free comfort during your active pursuits. The gusseted, streamlined design gives you maximum maneuverability and a full range of motion, no risk of constricting or squeezing your most sensitive areas. These nylon and merino wool boxers also have a comfy elastic waistband and flatlock seams throughout. This flatlock seam construction prevents chafing and skin irritation.
Also good to know: The moisture-wicking, high-quality Icebreaker Merino Men’s Anatomica Zone Long Boxers are machine-washable.
- Excellent breathability
- Gusseted design
- Corespun eyelet mesh insert
- Flatlock seams
- May shrink
Smartwool Men’s Merino 150 Base Layer Boxer Briefs
The Smartwool Men’s Merino 150 Base Layer boxer briefs are made of a special blend of 87% merino wool and 13% nylon. The merino delivers breathable warmth and helps wick sweat away from your nether regions, whilst the nylon makes the briefs flexible and form-fitting. The bottoms have an interlocking fit which aids thermoregulation and keeps your bottom properly insulated. The waistband of the style is also merino-covered for extra comfort.
Flatlock seam construction
And that’s not all. The Smartwool Men’s Merino 150 Base Layer also features a special flatlock seam construction to minimize chafing and minimize skin irritation when layered with other hiking clothes. These merino wool boxer briefs are machine-washable (warm water on a gentle cycle) and can even be tumble dried on low. That said, to prevent shrinkage and guarantee a garment keeps its shape, we always recommend letting any piece of merino wool clothing air-dry on a flat surface.
Amazon reviewers give the Smartwool Merino 150 Base Layer boxer briefs a big thumbs up on comfort and performance. Hikers say that though they are expensive, they are worth the money. Multiple in-depth reviews confirm that you can wear them all day long, even on the most strenuous hikes, without odors, chafing or discomfort.
If you want the best underwear for hiking and trekking and don’t mind spending a bit more, this could be your perfect fit.
- Great breathability
- High Merino wool content
- Odor-resistant properties
- Flatlock seams
- Can shrink or lose its shape
Adidas Men’s Sport Performance Climalite Boxer Brief (2 Pack)
- The sport performance 2-pack is what you need if you're looking for all-purpose, do-anything underwear.
The Adidas Men’s Climalite Boxer Brief is made of soft, stretchy fabric with moisture-wicking technology, aimed to keep you dry even in sweaty scenarios. The fabric of this synthetic underwear is a blend of 91% polyester and 9% spandex, which creates a soft and form-fitting shape. The fabric of these undies is also quick-drying, ideal for when you want to handwash them on the go and don’t have hours to let them air dry before packing up camp.
Another perk is that the Adidas Men’s Sport Performance Climalite Boxer Brief is designed to move with you, enabling a full range of motion without restricting your ‘equipment’. The sports performance fit is further enhanced by soft stitching, a tag-less waistband, and a no ride construction. The Adidas Men’s Sport Performance Climalite Boxer Brief is also machine-washable and is available in a wide range of colors.
Though it has many perks, we reckon the very best part about these sporty briefs is the price. Super affordable, even for those on a budget, the style comes in a 2-pack with an outstanding value-for-money appeal. As its thousands of 5-star reviews on Amazon confirm: this truly is a steal in the men’s underwear category. It may not be specifically designed for hiking, and it does lack some of the insulating and odor-resistant properties of high-end merino wool boxers, but for the price listed, we think you can’t go wrong in bringing a few of these quality boxer briefs on an upcoming hiking trip!
Also good to know: the Adidas Men’s Sport Performance Climalite Boxer Brief is also available in other underwear styles and materials, including midway, trunks and briefs, and a Performance Engineered Fit made of breathable mesh.
- Outstanding value-for-money
- Sports performance fit
- Not very odor-resistant
- Not the most durable
Each style in this Best Hiking Underwear overview has its specific pros and cons, and which one is ‘the best’ depends fully on where and when you plan to wear the boxers. For hikers that often find themselves in colder weather conditions, insulating options – such as the Icebreaker and Smartwool briefs – may be a perfect, warm fit. Though these merino wool boxers help regulate temperature and keep your crown jewels firmly insulated, they are also breatheable enough to prevent things from getting stuffy. Plus, their natural moisture-wicking properties help keep you dry and comfy, all day long. The trade-off is their pricing: which is quite a bit higher than that of synthetic underwear. So, if you’re on a budget, or simply don’t need insulation, a cheaper synthetic option could be a much better fit. Though more affordable, the synthetic options on this list don’t compromise on comfort. For example, the ExOfficio Men’s Give-N-Go Boxer Brief still comes with all the premium perks you should look for in hiking underwear, including odor-resistant properties thanks to its antimicrobial treatment and moisture-wicking abilities. And if you want even more bang for your buck, the Adidas Men’s Sport Performance Climalite Boxer Brief delivers on that buying factor. This 2-pack may lack some of the odor-resistant properties and premium performance of higher-priced hiking underwear, but it still offers a comfortable ‘sporty’ fit that moves with you and can wick moisture and sweat away from where it matters most.
You simply have to determine which buying factors are most important to you. For example, want maximum odor control? Choose a style with antimicrobial properties. Want maximum protection against chafing? Choose a longer boxer silhouette for extra coverage.
Rest assured: you can’t go wrong with any of these products, and all are fantastic undergarments to upgrade your hiking comfort (and give your crown jewels the royal comfort they deserve!)
If we could only buy one product from this Best Hiking Underwear overview, we’d invest our money in a pair of merino wool briefs. So, that narrows the choice down to the Smartwool Men’s Merino 150 Base Layer Boxer Briefs, and the Icebreaker Merino Men’s Anatomica Zone Long Boxers – which are both winners to us.
There isn’t a style that reigns supreme, as both deliver on outstanding quality, comfort, and the ability to regulate temperature and wick away moisture and sweat. They differ slightly in style, the Icebreaker Anatomica Long Boxers are longer on the leg, ideal for hikers who tend to suffer from chafing and want more skin coverage from their underwear. The Smartwool Merino 150 Base Layer has a classic, slim-fit with soft, non-chafing flatlock seams.
If you want to treat your nether regions to the very best underwear on the market, both these briefs are worth the splurge.
