Mountain Alert Camber – A directional version of our Alert Camber, built for edge hold, control, and pop. The tip and tail feature early rise with the tip being slightly more exaggerated for increased float in powder and ease of entry into turns.

Flex Rating – 8 (1 Soft - 10 Stiff)

Directional

Poplar Light Core – 100% FCS-certified wood. Strategically placed super lightweight paulownia wood throughout the core to reduce weight but maintain a snappy feel. Strips of hardwood are placed underneath the bindings to reduce board breaks at the binding line and increase insert retention.

Carbon Stringer – A 20mm wide carbon fiber stringer running tip to tail to increase overall pop and response without increasing torsional flex to keep the board feeling lively and nimble underfoot. Carbon stringer is the most effective way to add pop without increasing weight.

Carbon V Stringers – Strategically placed in a V pattern in the tip and tail for increased response from the binding to the contact point. This gives the board endless snap in and out of turns and an overall increase in pop.

Urethane Sidewalls – More durable against impact on rocks or rails to prevent your board from delaminating when you get caught slippin’ in the park or backcountry.

Sintered Base – More porous for maximum wax absorption, and more abrasion-resistant. In other words, it makes the board faster and more durable!
