The ProTec The Classic Mountain Bike Helmet has that "classic" look that will never die, hence the name! Whether you are new to the game or an old pro, there's one thing you likely have in common with the other skateboarders and bike enthusiasts: you want to keep your head intact! Not only is the Pro-Tec Classic the most distinct helmet on the market, the EPS foam liner certifies it to meet CPCS Bicycle Helmet and ASTM Skateboard Helmet standards.
