“This is by far the best groin protection system I have ever used. I have already been tested (not on purpose) numerous times and from different angles. Little to no pain on shots that would have brought me to my knees with my previous protection system. My only regret is that I did not make this purchase sooner. I am already preaching the value of the investment to my teammates and they all are aiming to make this purchase soon. I am a mixed martial artist that studies all martial arts systems. Thank you Diamond MMA.” -Customer Eric P.

Protection You Can Trust

Backed by a 100% satisfaction guarantee, you can trust that if you don't love it, you'll be taken care of. Plus, if you don't trust us you should trust the hundreds of positive reviews all over the web and professional athletes wearing and talking about our products. 

Superior Materials

We've literally spent years engineering our products and are still tweaking our designs to ensure our jock is always the best it can be and the best on the market. We are constantly sourcing materials to ensure our products are made with the best materials out there. 

Focus on Comfort

Obviously protection matters. But so does your comfort. The reason so many guys don't wear a cup system is because it's simply uncomfortable. We designed a cup and corresponding jock system that is so comfortable you'll forget you're wearing it. 

Designed By Experts

Designed by a team of award winning designers, Stanford University engineers, and most importantly, athletes practicing in the sport testing the products day in and day out.
