Things to Consider When Buying Men’s Underwear for Hiking
When it comes to performance-minded outdoor activities, conventional cotton men’s underwear just doesn’t offer adequate coverage. Athletes prefer the benefits of breathable, moisture-wicking, temperature-regulating fibers, such as merino wool and specialty synthetic fabrics.
Merino wool is an all-natural material that is naturally odor-resistant, insulating, and moisture-wicking. Since most Merino wool coming off of sheep’s backs in the mountainous regions of New Zealand, its prices are far from low. Still, this hearty material will last a lifetime when cared for properly. This fabric also has an incredibly rapid drying capacity.
What’s more, it is virtually wrinkle-resistant and does an excellent job of moderating body temperatures. Merino wool pulls moisture away from the skin. It has an impressive absorbency rating. As a result, it’s a premier base layer for activewear.
On the other hand, synthetic materials are often engineered to mimic the natural texture of merino wool. While these synthetic materials tend to wear out faster and do not always offer the same level of protection as natural fivers, they do provide a price advantage.
Merino wool and some treated synthetics boast natural antimicrobial properties. Merino wool is coated in a natural oil called lanolin. Lanolin is naturally antimicrobial. It boasts the power to fight off odor-producing and water-born bacteria. Synthetics are also treated with antimicrobial additives and coatings. Zinc- and silver-based coatings are typically used to prevent bacteria from clinging to underwear. Antimicrobial coatings fend off bad odors caused by lingering bacteria.
With that said, these materials lose some of their germ-fighting potential when they are treated with harsh cleaning chemicals and excess drying cycles. Always opt for gentle machine cycles with hand washes in lukewarm water and mild detergent. Whenever possible, hang dry your hiking undergarments to prolong their lifespans.
Construction and Durability
Manufacturers use a variety of clothing construction techniques to ensure that their hiking undergarments are durable enough to withstand several uses. Elements such as flatlock seams and reinforced waistbands ensure that underwear can face the trials of the backcountry and your industrial-strength home washing machine. Loose threads and surface pilling are almost always a sign of inferior garment construction. Undergarments should be made from thin, light materials that hold up well to constant movement and abrasion.
When it comes to hiking, most men prefer to wear either loose-fitted boxers or more skin-tight boxer briefs. Both of these undergarments extend well below the crotch area to cover a few inches of the upper thighs. Loose boxers provide adequate coverage, but they are more easily bunched and twisted. Briefs are not the best option, as they fail to protect the thighs from potentially abrasive top layers of clothing. Boxer briefs provide adequate skin-tight protection that’s perfect for athletic performances and outdoor adventures.
For the best results, ensure that your hiking underwear offers adequate waist and in-seam dimensions. Some materials are stretchier than others, meaning a single size is suitable for a variety of body types. If you’re going to opt for a more form-fitting cut, then ensure that the material is soft and flexible enough to prevent chaffing and riding. Inadequate fits almost always result in bunching and wedgies.
Finally, don’t forget about the placement of the waistband. While modern outerwear cuts pair well with low-rise undergarments, overly tight or loose waistbands can cause discomfort and annoyance. Another useful element is a fly, which enables users to quickly relieve themselves before returning to their endurance tests.
Most manufacturers try to minimize their customer’s commitment when it comes to washing. We’ve all dealt with clothing that shrinks, fades, and shreds under the pressure of a washing machine and dryer. While natural fibers like merino wool require a bit of extra attention, they can usually make it through several gentle spin cycles without turning into rags.
We recommend that you stock up on an extra pair or two to ensure that you can adequately hang dry your garments and, as a result, extend their potential lifespan. Most manufacturers offer precise washing instructions. Take the time to follow these closely.

Which Underwear Style is Best for Hiking?
For most hikers, the best underwear style for hiking is a matter of personal preference. Focus on finding an undergarment cut that creates a weather-appropriate foundation. Make sure that the materials mitigate moisture, odor, and chafing. Ensure that your pick offers adequate coverage and does not inhibit the performance or comfort of additional garments.
How Should Hiking Underwear Fit?
Most modern-day hikers prefer to wear slim-fit or slightly loose low-waist boxer briefs when hiking. A low-profile foundation gives athletes more wiggle room when it comes to adding on top layers. The undergarment needs to be stretchy and free-moving with an ergonomic cut that provides plenty of adaptability in the waist and crotch. Most hikers prefer cuts that extend over the thighs, as this extra layer of fabric prevents top layers from rubbing up against the skin.
Overall, your hiking underwear should offer snug, extensive coverage that is balanced by breathable materials and ergonomic fabrics.
