Re: bio flex cup questions
I've worn Shock Doctor Ultra Carbon Flex cup in a jock, almost since day 1. This is sold as a package (get the "Ultra", it's $25, but the supporter is super comfortable and fits awesome) I have taken plenty of kicks to the groin- never a flinch or a pinch. Best cup Ive worn, I'll never go back to cheapo cups like Bike, XO or wal-mart special. It flexes on purpose, and does exactly what it's supposed to do- protect the nuts, and as comfortably as possible. A+ in my book.
Comp shorts with cup pocket are a no-go in my book. The cup kind of "floats" over the area instead of being snug in place and that makes me nervous, aside from being uncomfortable. I'd say save your money and just go with the jock. If you want to wear the shorts, wear them over your cup/jock.
