The Patagonia Everyday Boxer Brief combines the Fair Trade Certified organic cotton and Tencel lyocell fibers, they give you the comfort of a lounging weekend and the performance to get things done. The fabric breathes to keep you cool and feels soft and light on bare skin. A brushed elastic waistband stays put without binding, chaffing or bunching up under your pants. The contoured fit and tagless design let you transition from a morning meeting with the boss to an afternoon of bouldering. With a smooth, self fabric, fully functioning fly.
