Ability Level
Intermediate-Advanced Whether you’re a progressing intermediate exploring new runs and terrain, or an accomplished rider seeking new thrills, the majority of skiers and snowboarders fall into this level. Intermediate to advanced skis and snowboards may be somewhat wider or stiffer than beginner-intermediate skis and snowboards, usually with a stronger wood core and sandwich sidewall construction. Intermediate to advanced boots and bindings range from softer flexing freestyle options to stiffer choices built for stability at speed.
