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.

Flex Rating
Medium The amount a snowboard flexes varies significantly between boards. Snowboard flex ratings are not necessarily standardized across manufacturers, so the flex may vary from brand to brand. Many manufacturers will give a number rating ranging from 1-10, 1 being softest and 10 being stiffest. Here at evo we have standardized the manufacturers' number ratings to a feel rating ranging from soft to very stiff. Generally you will find flex ratings of 1-2 as soft, 3-5 as medium, 6-8 as stiff, and 9-10 as very stiff. Flex ratings and feel may ultimately vary from snowboard to snowboard.
