The Diamond MMA Athletic Cup incorporates a co-molded elastomer design coupled with a polycarbonate core to provide uncompromising comfort and protection for the athlete. The cup's patent pending design protects sensitive groin muscles and nerves with a specially designed ergonomic soft elastomer edge. The core of the cup is made with a rigid but flexible polycarbonate, the same plastic material utilized in bulletproof glass. Designed by award winning designers and Stanford University engineers, the cup has been approved by Doctors and Urologists as the best groin protection on the market. In combination with Diamond MMA brand compression shorts with jock or Diamond MMA 4 strap jock strap systems, the cup stays completely in place with dedicated straps to minimize both lateral and vertical movement. The Diamond MMA cup is used by professional athletes and the US military.
