Instead of starting with a standard construction and cutting material away to save weight, Prolite does the opposite. It starts with the slimmest possible profile and then it builds up reinforcements in key areas where strength is needed.energy BackboneThe energy Backbone is a reinforced, asymmetric backbone that provides extra strength for powerful skiing plus enhanced lateral energy transmission for better edge grip.SpecificationCategory: AlpineFlex: 85Last Width: 98-102Custom Shell: YesCustom Liner: YesPower Strap: 35mmVolume: Medium-Low Clips: n/aSole Unit: Alpine (Adult ISO 5355)Pin Inserts: NoHike Mode: NoWeight (g): 1560Binding Compatibility: Alpine, Grip Walk, Walk To Ride, Multi Norm
