The Zen brief is made from see-through mesh fabric in back and a contrast panel in the front that gives you a bit of modesty, sure, but definitely highlights your finest assets. Wear when sexy-meets-sporty is in. Feels very lightweight on the body. Made on 100% Ban-Lon Nylon. Color: Blue. Medium. Chest: 38"-40". Neck: 15"-15.5". Waist: 30"-32". From Jack Adams.
