I am a 5 feet 4 inches tall adult so it is tough to find martial arts equipment that fits well. Most cups run too long, so they don't fit properly on me. On the other hand most youth cups aren't wide enough for an adult either. This cup solves the problem as it is wide and short.

I had tried a few cups, including the cups with shock doctor compression shorts (bioflex), but there were all really uncomfortable. The bioflex was really thin in width and lets just say it was not comfortable.

Overall it is a great cup for grappling. The one downfall (or positive) is that it is that the alloy shell is really hard. Throw on a tight triangle on your buddy and his chin will be getting smashed into metal. Flatten out a guy on his back and he will definitely feel the cup on his spine. You get the point.
