WaveCel helmet safety technology
WaveCel is a revolutionary helmet technology designed to be more effective than traditional foam helmets in protecting against certain cycling-related accidents. Its collapsible cellular structure lines the inside of your helmet and is designed to work like a crumple zone to absorb the force of an impact before it reaches your head.
