LESS EFFORT, MORE FUN. THAT'S THE WHOLE POINT OF THE K4.5 JRS GW. Built around Kästle's Junior Rail System, it gives young rippers kid-friendly handling, an easy flex, and a featherlight, tool-free step-in. GripWalk compatibility covers alpine and GripWalk boots alike, and it's sized for 100-120 cm skis like the RX12 Junior, so the next generation can focus on skiing, not gear.
