Performance for Any Adventure Our Men's Merino Sport 150 Boxer Briefs are designed to perform no matter the trail/road/adventure you're on. They feature a double front panel designed to provide extra support, a flatlock seam construction designed to help eliminate chafing, and a wide elastic, Merino-lined waistband designed for added comfort. They're made with a fabric that combines the sweat management, temperature regulation, and odor resistance of Merino with the durability and quick drying time of polyester. These briefs are made to help keep you cool and dry while you're out doing what you love.
