The All Sport Brief Jock from Jack Adams brings two styles together, a jock in the front and a brief in the back. The All Sport is the perfect balance of athletic style and performance. The smooth, narrower straps expertly support while the contoured pouch keeps you cool and dry. Thin straps sit flush across your body reducing the appearance of underwear lines under your clothing. Excellent for sports or working out, this brief jock offers a body conscious fit in a breathable, lightweight moisture-wicking material. 5% polyester and 5% elestane.
