Pro Tec Classic Helmet really is the CLASSIC skateboard helmet. No other helmet is such a firm staple in skateboarding. What makes it special? it's multi-impact soft foam (more like a football helmet) and designed to take multiple hits. It does not conform to CPCS standards like hard foam bike helmets, but it has been proven for many decades to be the prefered safety equipment. Skateboarders don't need some anvil test to know what protects them the best and for nearly half a century, it's been pro tec.
