POC's iPhone case is engineered like a helmet. It has an outer shell made of Polycarbonate to support anti-denting, low friction and to spread the energy over a larger area and therefore reducing impact energy. On the inside of the shell there is a shock absorbing liner material, POC's patent pending VPD. The VPD is what makes the big difference, reducing impact energy by as much as 56%. The upper part of the shell is shiny to slip easily down a pocket, up-side-down and the lower part in a rubbery finish to support grip, when pulling out and handling.
