The key to this underwear is in the fabric and the fit. You’ll find boxer briefs made from quick-drying synthetics that are great for high-output activity, and others using merino underwear fibres for outstanding temperature regulation and odour resistance on multi-day trips. Many pairs feature clever construction like flatlock seams to prevent chafing and ergonomic pouches for better support. This is technical underwear, made to keep you feeling good so you can focus on the trail ahead.
