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. For those who like to get aggressive, it includes the Fidlock® magnetic strap buckle for easy one-handed operation, a built-in universal camera mount, plus airflow control venting.
