These superbreathable no-fly briefs are the minimalist's choice for high-octane endeavors. Made from a blend of fast-wicking quick-drying polyester (71% recycled) and 7% spandex that has both stretch-mesh (for support) and open mesh (for cooling airflow). Soft edging at the leg openings and a seamless waist won't roll or create friction against layers. With a smooth front panel for opacity. Recyclable through the Common Threads Recycling Program.
