#See How A3 Changes the Game

Traditional Groin Protectors Fail When You Need Them Most.

Most groin protectors are uncomfortable, unstable, and a pain to put on. They shift during impact, dig into your skin, or even shatter — forcing many athletes to risk it all by not wearing one at all.

That ends now.
