    Pros: Very comfortable, holds cup in place, great for all sports, easy to wash, very durable.

    Cons: None that I have discovered so far. This is the best cup/jock supporter that I have found. Works really well with the Diamond MMA cup. I haven't tried with any other brand's cup.

    Comments: Go for it. Trust me.
