Fit is the perfect size you can wear during play or out. The best c-ring is one that fits the way you need- tighter ones to kepp you hard for play, big rings that push your junk out. We made it comfortable, there is a dip in the ring that goes behind your balls for less pressure on your taint. Less grip to wear longer.
