The Altitude helmet is constructed from an innovative new thermoplastic poly alloy outer shell material. This all new material allows for one of the lightest helmets in its class, with a starting weight of just 1260 grams. The Altitude helmet comes in 9 total sizes (Youth SM-LG, Adult XS-2XL) from 3 individual outer shell molds. This results in a smaller overall shell profile, a dialed in fit, and the lightest weight possible.
Goggle performance is directly affected by the fit of the goggles in your helmet. Mixing a different brand goggle and helmet will only result in decreased goggle performance. The 509 goggle and Altitude helmet combo was designed to fit and function perfectly together. Both products were specifically engineered for optimal performance from an industry leading combo fit. The Altitude helmet was engineered from the ground up to provide an improved goggle fit over our previous Evolution shell. Experience the first and only true helmet & goggle combo in the snowmobile industry.
