The Cock Ring Nitrile is the same material used to make gloves for emergency room doctors and nurses. Why Nitrile? Because Nitrile is 100% skin-safe and hypoallergenic. Nitrile is also compatible and safe to use with all types of lubricants. Nitrile is stronger and holds its shape better than latex or rubber and it stretches slightly to achieve maximum constriction without sacrificing comfort.
