The Redster S9 FIS S9 FIS J-RP is a quick and nimble FIS approved slalom ski for junior racers. Atomic's Power Woodcore is made from a blend of ash and poplar that keeps your little racer stable and smooth as they are bashing the gates. A Titanium Powered Layer above and below the core dampens out vibrations and adds even more horsepower to the ski. The Full Cap Construction helps reduce the weight and increases the maneuverability and agility to zip through the tight gates. The Junior Race Interface allows the ski to flex naturally and delivers full-on edge contact for more control. Atomic's Active Camber loads the ski with rebound and enhances edge grip when the course is firm.
