The Björn Borg Performance Boxer 3p is a classic five-pack of top training underwear made from soft recycled polyester stretch. The fabric leads away moisture to keep you dry during the sweatiest workouts. They have a mid-rise waist and a medium leg length with the perfect fit for better performance. With smooth seams and elastic to avoid chafing, and a soft elastic logo waistband in microfibre for extra comfort.
