The Atomic Redster J4 is a junior piste ski built for young racers and confident cruisers looking to develop their carving technique on groomed slopes. It combines a race-inspired profile with features tailored to smaller skiers.
With a 12 m radius at 150 cm, the Redster J4 encourages quick, confident turns, while its 113.5/68/97 mm sidecut enhances edge grip and stability through each carve. Weighing just 1 436 g per ski, it’s light enough for kids to handle without feeling unwieldy. The package includes Atomic L 6 GW CA bindings with 70 mm brakes, offering reliable release performance and compatibility with both alpine and GripWalk boots.
In ski terms, the radius refers to the curved path the ski naturally follows—12 m means shorter, more responsive arcs. The sidecut dimensions (tip/waist/tail) describe the ski’s hourglass shape: a wider tip and tail combined with a narrower waist make it easier to initiate and hold clean turns. These design choices help young skiers build control and confidence on piste terrain.
