The Sierra Series is very unique in design. Built with Directional Quad Side-cuts, the edges are bumped out under boot, which give you a huge advantage when holding an edge at high speed. With a medium tip to tail flex, with very thin tip and tail profiles to cut down swing weight. The Sierra Series at its core it built to handle some of the gnarliest terrain one can get themselves into on the mountain. If you are more of an intermediate rider, this is a great board to up your all mountain progression.
