Diamond MMA's patented quad strap designensures that your cup stays in place againstyour body so that no matter how you moveyou stay protected.

  • The Diamond MMA cup geometry deflects and distributes force. Soft elastomer edge minimizes vibration and chafing or rubbing. The rigid cup is made from the same material as bulletproof glass. Eliminate the possibility of permanent injury to your penis and testicles.


  • Made from military grade elastics and premium construction, the Diamond MMA groin protection system leverages a high performance 4-strap jock system to hold a specially designed athletic cup in place within a perfectly tailored cup pocket. This patent pending system prevents both lateral and vertical movement of the cup. The Diamond MMA system has a drawstring providing a custom fit.

  • Designed by award winning designers and Stanford University engineers, the system has been approved by Doctors and Urologists as the best groin protection on the market. Diamond MMA products are used by professional athletes worldwide without sponsorships.
