The high-performance KORE 91 W has a lightweight construction and vibration-absorbing properties, which means more energy for carving up the frontside or exploring the backside. HEAD blends core materials designed to reduce weight without sacrificing performance such as light Graphene fused into the rockered tip and tail, light but stiff Karuba wood and triaxle woven carbon. HEAD's new topsheet shape adds durability to this easy-to-turn freeride ski.
