The Faction Studio Grom FS Ski is a youth twin-tip ski for young skiers learning park, with a shape that rides forward and switch alike. Rocker in the tip and tail softens landings, and 2. 5 millimeters of camber underfoot adds pop off the lip of a jump. A lightweight poplar core keeps the ski light for small legs, and carbon stringers add stability without adding bulk. What Our Gearhead(R) Experts Are Saying:"My kid clipped a rail and slid a box edge on the first park laps, and the ski barely shows it. I stopped wincing at every landing once I saw it could take the abuse."
