Not really, but Diamond (@DiamondMMA) reached out to one of MMA's most prominent figures, "Big" John McCarthy, and he likes our design and feel. He's just been lucky enough to avoid a nut shot so far. Once he does get hit down there while wearing Diamond, he'll realize the product's full protective potential. We are honored that a man who's spent his entire career protecting professional athletes would enjoy our safety gear! 

How many hundreds and thousands of nut shots in the cage do you think "Big" John wishes he never had to hear and see? The more Diamond wear that gets around, the less he'll have to worry about groin stoppages.
