The Xact-Fit system by Perfect Fit is the first cock ring sizing system designed to fit you perfectly - without too much pull, and just enough restriction to give you an impressive erection.
Made of a plush soft touch silicone the Xact-Fit ring is premium quality and incredibly strong. So the rings are effective, but easier to get on and off than a metal ring.
