Less Weight, More Fun Since its debut, the Stage helmet has redefined mountain bike safety, style, comfort and ventilation. Stage is the lightest full-face helmet in its class, and combines MIPS (Multi-directional Impact Protection System), EPP (for slow speed impacts) and EPS (for high-speed impacts) in one sleek package, that sets the standard for mountain bike enduro helmets.A Polylite shell w/fiber reinforcement and Polyacrilite injected chin bar w/EXOskeleton adds strength without sacrificing weight. 11 high-flow air intakes and 14 exhaust ports and large ventilation chin bar openings aid in cooling and comfort in all conditions. The TLD Stage Helmet also includes an X-Static helmet liner that is moisture-wicking, quick-drying and odor-fighting. A Fidlock buckle and lightweight hardware round out the overall package.
