Altitude 2.0 Carbon Fiber Helmet
Reinvented to ride even harder, the second generation of the bestselling 509 Altitude series unleashes a whole new animal. Leading the charge is the 509 Altitude 2.0 Carbon Fiber Helmet with a new hand lay-up carbon composite construction that’s lighter, stronger, and straight-up sleeker than anything before it.
