100% of the net proceeds from the Duck Cancer Briefs go directly to the Rookie of the Year Foundation. This foundation, inspired by our founder’s son, Rookie Flaitz, is dedicated to improving pediatric cancer treatment, care, and research. These briefs include four-way stretch, a breathable MicroMesh pouch, and durable flatlock stitching. The PSD 7” Standard Length Briefs won’t roll or ride and were built for everything, from everyday wear to your toughest workouts.
