Fun and top quality in one package. Premium-quality skis for kids. The Kästle KX66 PREMIUM (JRS BASE) + K4.5 JRS GW have awooden core and Hollowtech 2.0 technology. And they have a durable base. They are considered to be the most “pumped up” children's skis. Thanks to the mascot Holly’s ears, their first turns will be fun and will motivate them to ski more. The ears help to keep the skis parallel and help them with stopping.
