Formfitting, lightweight, quick-drying boxer briefs made of a recycled polyester double-knit rib for softness and stretch. Even when your day includes making a public presentation, your Patagonia Lightweight Boxer Briefs will remain cool, dry and airy. Made of no-fuss, recycled polyester double-knit rib fabric that stretches and recovers easily, they're soft, comfortable and more than able to go the distance with any athletic endeavor. A tagless brushed elastic waistband adds all-day wearability and a cover-stitched hem provides a smooth glide under shorts or pants. Polygiene permanent odor control resist odors and the supportive front panel has a fully functioning, self-fabric fly.
