The Head Mini Monster SLR II Ski with 4.5 bindings offers all mountain performance and a cool graphic that will match Dad's Monster 108 skis. This ski is very maneuverable especially since it has ERA 2.0 rocker with 80% camber and 20% rocker. It also has a junior power frame, durable extruded base and structured surface to prevent scratches and dings. The SLR 4.5 binding comes included with a DIN range of .75-4.5 and is adjustable for boot sizes 199-286mm or 239-323mm depending on the length. We recommend this ski to beginner to advanced junior skiers looking to expand there horizons and ski the entire mountain.
