Abstract
The invention features a soft foam sled board for use by a sitting or kneeling rider to slide over a snow or ice covered surface. The sled is prepared from a shaped polyethylene foam core, and at least the bottom surface of the core is covered by a slick, polyethylene film/polyethylene foam sheet laminate which provides little frictional resistance between the sled board and sliding surface, and provides an impervious outer surface to the board so as to resist puncture and water infiltrate. The sled board has one or more rails, ribs, or fins embedded below the body weight of the rider so as to either protrude from, or jut into, the board. The fins enhance the ability of the sled board to travel down the hill in a straight, forward direction.
