These ultra-supportive boxer briefs have an open-weave mesh that provides the added benefit of air-conditioning. The polyester (71% recycled) fabric is fast-wicking dries quickly and has 7% spandex for stretch; the seamless waistband and soft leg edges won't roll or bind. The gusseted flat-sewn 6" inseam (size M) is offset to prevent inner-thigh chafe. Fly-free with a smooth front panel for opacity. Recyclable through the Common Threads Recycling Program.
