This all-season sled conveys riders down slopes both during frigid winter and hot summer days. Similar in concept to the informal, fair-weather competitive pastime of ice blocking where one rides a frozen block of ice down a hill, two plastic ice molds that attach to the bottom of the sled are removed, filled with water, and frozen in a standard refrigerator freezer. When re-attached to the bottom of the sled, they reduce the friction between the ground and the sled (especially on hotter days that encourage melting) for a half-hour of snowless summer sliding. Best when used on short grass. In the winter with the molds removed, its smooth yet durable high-density polyethylene shell and runners provides exhilarating rides down snow and ice-covered hills. For riders up to 200 lbs. Durable high-density . 38" L x 20 1/2" W x 6" H. (10 1/2 lbs.)
