The Jones Snowboards Project X Is the height of technological advances in the Jones snowboards range. With a new Carbon “Ultra” construction, this is one of the lightest boards on the market but it has all of the reinforcements for the most aggressive of big mountain riders. Carbon in place of fibreglass adds to the stiffness and reduces the weight so this board is ideal for a light hike into the backcountry before dropping in for whatever line you choose.
