Additional features of the Turbo Dream include a one degree edge bevel, Hybritech construction and an all-terrain rocker range of 10-7mm/220-180mm. K2 states that hybritech construction is the "most efficient way to make a snowboard without sacrificing one ounce of performance." More specifically, the Hybritech type of construction is designed so that the sidewall runs along the surface and flows into the nose and tail which is ultimately meant to provide low swing weight, better turn initiation, and durability.
