I'm currently using a flexible Muay Thai cup from Shock Doctor and went to use it for a bjj session and the pain is too big for the groin.
I need the best groin protector
that is convenient and useful. I've heard of spider guards, but I've read different opinions, saying it's convenient, but it's not good to keep the pain from blowing. I ask because I just do not want to spend money trying different cups.
