TLD's Stage helmet: 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.
