You don’t want your underwear to lead to rubbing or chafing in sensitive areas. You’ll also want a pair that is quick-drying, breathable, and lightweight. Cotton is neither of these things. The best underwear for hiking is made of Merino wool, Nylon, Lycra, or a combination of those materials. Merino wool is one of the most popular choices because it’s soft and extra breathable. ANTIMICROBIAL Whether we want to admit it or not, we sweat down there. The best underwear for hiking should be antimicrobial. Antimicrobial material will help keep your undies fresh longer, which is especially important when you’re doing a multi-day hike and packing light. Merino wool has natural antimicrobial properties making it once again one of the best choices. Synthetic materials, like polyester, are often treated to provide antimicrobial properties. If antimicrobial properties are important to you, make sure you read the label before making any purchases. CONSTRUCTION AND DURABILITY Nothing is worst than having your underwear fall apart mid hike. The best underwear for hiking should be constructed with flatlock seams because they are more comfort and designed to reduce chafing. Look for underwear that does not have vertical seams going down the middle of your bottom for even more comfort. Hiking underwear should be durable and maintain its construction and properties after regular washing. CUT The cut of hiking underwear is a personal choice. Choose whatever cut or style you are more comfortable wearing. Most people prefer a more fitted cut, like boxer briefs for men and bikini briefs for women, because they are the most comfortable to wear with hiking pants and a backpack. High waisted underwear may feel too binding and rub against your pack. On the other hand, low cut or thongs may be too skimpy and lead to serious chafing. WASHING CARE Most people don’t even consider washing instructions when purchasing new clothes, but care requirements for hiking underwear are important. If you are planning a multi-day trek then you want a pair of underwear that can easily be hand-washed and hung to dry. You want underwear that is quick-drying so that you can ensure you won’t be putting on wet undies the next morning. Additionally, it’s also nice to have machine-washable underwear for when you’re not on the trail.
