Our ultra-supportive Active Sport Boxer Briefs have an open-weave mesh that provides the added benefit of air-conditioning. The seamless waistband and soft leg edges won't roll or bind. The flat-sewn gusseted 6" inseam (size M) is offset to prevent inner-thigh chafe. Fly-free, with a smooth front panel for opacity. Now made from fast-wicking, quick-drying 93% polyester that's 71% recycled; with 7% spandex for stretch. Recyclable through our Common Threads Recycling Program. Formfitting.
