Jock Sizes I Need To Buy A Prtector Cup/jock Strap, Ok To Buy Online?

I need to buy a prtector cup/jock strap, ok to buy online? - jock sizes

I am an adult in LIGA adults play softball and played in 1 game table relaize I must protect my children seriously. I have never bought a cup or a jockstrap, so that did not even know the difference.

Do I need one or two? Would it be wise to order online only? How do I know how great I am (yeah yeah, put *** as noted):

Thank you.
