2" Jockstrap. The most popular version with a 2-inch waistband. The ultimate sports supporter is now even better. The classic BIKE Jock has been redesigned to provide you with even more support and comfort. The waistband is made from a softer, plush-like fabric. Still as durable as ever for sports, but now comfortable enough to be worn as regular underwear. 3/4" comfort leg straps and moisture-wicking woven pouch. With the support you expect from a sports brief, but even more comfortable than before. Materials for the pouch: 55% Nylon, 25% Rubber, 20% Cotton; Waistband and leg elastic: 70% Polyester, 30% Rubber.
