Got this with Diamond cup in May, took first square shot ever in cup. Felt same as getting hit in shin guard! Cup stays firmly in place and never has to be adjusted. Highly recommend this combo.

I bought the compression short jock for this season and its been uncomfortable. I ordered the same size as the original jock I purchased last year, but the straps have been rough on the inside of the shorts. I would order the size bigger or just the jock and use your own compression shorts.

This feels good, fits well and keeps the cup in place.
