This is without a doubt the very best support system I have ever used. The cup doesn't move once you put it where you want it. The protection is awesome!

Best jock strap I have ever used! Cup is stationary when I umpire and when I catch in my adult baseball league. Very, very comfortable.

Great product. Cup is stationary and does not move. When calling a double header I don't bother removing the cup when I'm in the field. As comfortable as a jock/cup can be. The only issue I would say is the draw string, it's a solid string and unable to tie but that is minor.

Questions About This Product

Q: Is the Diamond MMA Quad Strap Jock built / designed into the Jock shorts or is it a 3 layer process?
– Beverly Pocock

The Diamond MMA Quad Strap Jock is integrated in the compression shorts. You will only need these shorts and the Diamond MMA Athletic Cup for maximum protection.
