The main difference between a barbell pad and Hipsarmour is the material. Instead of cheap foam with poor durability and pressure absorption capabilities, Hipsarmour is made of PU (Polyurethane). PU is the highest level of durability, abrasion resistance, and absorbing pressure capabilities. To ensure extreme durability, Hipsarmour combines two different densities. An inner part of greater density where the bar is in contact with, and an outer part of the pad with a lower density so that it adapts to the body and provides enhanced comfort.
