Runderwear Boxer - Men

The Runderwear Boxer for men is a seamless anti-chafe running boxer, engineered for running and backed by Runderwear's zero-chafing guarantee. Made from recycled, GRS-certified fabric, it's the least exciting piece of kit you'll buy and the one you'll notice most when it's missing.

Runderwear built them for long-distance runners, road racers and anyone who refuses to let discomfort slow them down, and they're just as good for training and everyday workouts. Seamless construction eliminates irritation for a smooth, distraction-free fit, while the lightweight, breathable fabric wicks sweat away to keep you cool and dry. It's the boxer for marathon build-ups, hot summer long runs and every sweaty session in between.
