Preferred by most divers for its general comfort, the 1-inch crotch strap is ideal for fastening a harness and backplate securely to a diver's body. By using a crotch strap, divers can reduce the likelihood of their gear slipping upwards on the body in the water, resulting in the tank hitting the back of the head during a dive. Nylon webbing provides strength, yet is soft and won't dig into the body. The 1-inch (25mm) crotch strap comes with a slide release buckle and scooter ring for divers who scooter and want the convenience of a crotch strap that can be adjusted easily.
