The high-performance KORE 91 W has a lightweight construction and vibration-absorbing properties, which means more energy for carving up the frontside, exploring the backside or getting a great workout while touring. HEAD blends core materials designed to reduce weight without sacrificing performance including 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. Head Kore 91 Freeride Skis Womens | 149 | Christy Sports
