Top of the Redster Classic range, the Classic Skin Ski Atomic Redster C9 Carbon Skintec Medium is close in construction to the waxable World Cup model. It just has a different Nomex Featherlight core that's lighter and more forgiving, adapted to the behavior of a skin ski. Otherwise, it's still a true performance monster, with incredible dynamism at the end of push and ultra-efficient glide thanks to the combination of 100% Mohair Skintec skin, World Cup structure and BI 6,000 sole. As for the choice of the Medium Chamber, it's the assurance of great versatility in all types of snow and for all types of build. We recommend it for sporty skiers with a good technical base and excellent physical condition who want to train and progress with a World Cup-type model without getting bogged down with the choice of holding wax.
