  Ability Level

  

  Advanced-ExpertWhether you charge the steepest lines, hit the biggest jumps in the park or carve with race-like precision, advanced to expert level skis, snowboards, boots and bindings are for the more aggressive rider. In skis and snowboards, you'll often find layers of metal, carbon or other stringers for rigidity and power, while advanced to expert level boots and bindings are usually on the stiffer side of the spectrum for rebound and precision steering.
  
• Flex Rating: Stiff
  

  Flex Rating

  

  StiffThe 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.
