The Roots model features a time-proven template that provides both performance and versatility. This is a solid all-around performer that features a Kinetic polypro core with single stringer construction in 38″, 39″ and 40”. A second stringer is added for the 41", 42” and 43" sizes. At 44" we drop in bottom mesh to add more durability for the bigger riders. The Roots is your insurance policy, it is a board that you know will work every time.
