The Redster S9 Revoshock S from Atomic is a race ski built for carving short, quick turns on groomed slopes. At 165 cm, it focuses on precise control and responsiveness for skiers who enjoy driving tight arcs on piste.
This ski features a 12.5 m radius and a sidecut of 118–68–104, striking a balance between agility and edge grip during fast transitions. It comes mounted with the Atomic X 12 GW binding in red and black, offering a reliable connection whether you’re using traditional alpine boots or GripWalk soles. At 2991 g per ski, it delivers the stability you need when loading into demanding turns.
