evo.com | Head Ski Packages > A lightweight and versatile freeride option that not only excels on the groomed but loves a run through the bumps or a jaunt through the trees for variety, the Head Kore 91 Skis + Tyrolia Attack 11 MN Demo Bindings make the best of the patented Kore Multi-layer Carbon Sandwich Cap construction. Starting with a super light Karuba-Poplar wood core and adding a layer of Graphene for low-fat power, the Kore 91 will turn the most mundane of days into a delight. Karuba / Poplar Lightweight Wood Core Utilizing karuba wood in the core gives you the perfect balance of density, durability, and weight. Graphene Graphene is the strongest, thinnest and lightest material known to mankind. Lighter than wood and metal, yet harder than diamond or steel. Tip / Tail Rocker Subtle rocker in the tip and tail; camber underfoot. Structured UHM C Base The same high quality material used in Head's world-leading race skis is used here. Different structured running base for all conditions. Demo Bindings Come Mounted to Skis Always have a certified binding technician adjust your bindings. | Women's Head Kore 91 Skis + Tyrolia Attack 11 MN Demo Bindings 2023 - 163 in Black
