Jones Twin Sister. Featuring a CamRock profile and a friendly flex, the Twin Sister offers amazing float in pow, turns on a dime and is easy to ride switch or take into the terrain park. Jones completely redesigned the shape of the Twin Sister for 2021 by adding a more blunted tip profile, a 3D Contour Base 2.0 and Traction Tech 3.0 edges. The blunt tips reduce weight, Traction Tech keeps you locked in on firm snow and the 3D Contour Base helps you avoid catching your edge and makes every turn more effortless. To complete the redesign they upgraded to a new super fast and durable Sintered 8000 base and added stance options with a new Freestyle/Freeride Stance Pack.
