Kept getting my nuts smashed during rolls in BJJ

This cup solved all my issues, but the real magic is the jock strap. It’s stays perfectly in place so I don’t have to worry about catching a ball on the outside and can just focus on sparring. 10/10 won’t roll without one again.

Diamond mma cup saved my boys.

This cup is great. I’ve had 3 bad nut shots this year leaving bruises. This jock strap / cup combo is a nut saver. It fits tight and has no room for a devastating pinch of the boys between the cup and my groin haha. It’s great for striking sparring and full mma sparring . My boys can’t be happier !

Great product

Overall great product and worth the buy over the other brands I've experienced. Although there was a slight defect with the cup logo not being aligned. It didn't affect it's performance.

Great protection and comfortable 🥊

I’m so amazed that there is zero encumbrance to any action, even vigorously warming up in BJJ. Let’s see how it carries over to the hockey rink. Thanks guys 💪🏻❤️🥊
