The Alliance SSR helmet was developed through exhaustive lab research and real world testing. From passing the "looks" test at local bike nights, to passing people in the turns at the local track, we've made sure the SSR stands up to all challenges. Premier manufacturing processes assure that the helmet you have purchased meets the highest quality and safety standards in the world: Snell M2005 and FMVSS 218 DOT. The precisely engineered injection molded outer shell and energy absorbing dual-density EPS liner greatly reduce the possibility of head injuries in the event of an accident. The Alliance SSR also includes Icon's precision optics shield and HydraDryTM wicking interior.
