This is the ski created by none other than Killian Jornet. Will these skis turn you into a world class endurance athlete like Killian? Probably not, but they will be a first great step to getting there. This ski is the definition of light and fast as it was developed to aid Killian on his incredible adventures. It is made out of a Karuba wood core and the tips have inserts with Koroyd in them to increase dampening and shock resistance. The ski's stiffness and stability comes from a framework of carbon and flax and the binding area are reinforced with carbon yielding additional strength. Basically this ski is a machine built for a machine to go out and fly up mountains.
