It was pretty obvious which way the cup went and how it fit into the pocket on the strap. I just didn't know if you wore underwear with it, etc. Nathan wanted to just wear it by itself. Kept punching it with his fist, very impressed that it didn't hurt with the cup on...
So all's well that ends well. He is really enjoying sparring in karate, I may have to start taking classes as it looks pretty fun!
