Stability and control at speed are at the core of the Dynastar Speed 4x4 963. Advanced and expert skiers will appreciate the full-length power transfer of our 3D Profile. A Hybrid Core featuring a blend of beech wood and polyurethane delivers a smooth ride that quiets vibration and lets you focus on your turns. Full sidewall construction and a titanal layer add the finishing touches for a ski that's ready to test your speed limit.
