The Nordica Unleashed J skis come with a binding built to grow alongside a young skier, covering a DIN range from 0. 75 to 4. 5 across two plate sizes as they move up in height and ability. A twin-tip shape with camber underfoot and an early-rise tip and tail rocker keeps the ski forgiving through mixed snow, so the kid learning to read the whole mountain isn't fighting the ski while they're still fighting the terrain. What Our Gearhead® Experts Are Saying:"My kid grew two boot sizes over one season and this binding still had room to adjust without a trip back to the shop. That's the difference between a setup that lasts a season and one that lasts a few."
