Women's Chest Guard - Piranha Gear We thought about selling them in pairs, but just not much call for that (those girls probably working the circus anyway)... So we just sell them one at a time... Seems to work better that way... We designed these for doing most styles of combat martial arts like MMA, UFC, Karate, etc. though we know women buy them for kickboxing, Muay Thai, and Tae Kwon Do. The hard plastic protects your... well... you know... pretty good. But really it's not rocket science with these things - they're all about the same), but at least you can send ours back if you don't like them because we're so darned laid back about it! ;) NOT made of "paint covered foam" so it's going to last longer than 6 months and not end up cracking and falling apart.
