A sliding device for sliding on the ground down a sloped or inclined surface (grass, dirt, sand, synthetic turf, etc.) has an upper deck and a slide mechanism mounted below and in parallel with the upper deck. The slide mechanism has a slide base of an elongated planar member with opposite radiused ends, and an endless anti-friction belt entrained to slide around the slide base. The belt can be made of high-density plastic, rubber, or a track belt. The slide base surfaces and inner surfaces of the belt may be coated with plastic laminating material to increase slipperiness. The slide base has ends of selected radius of curvature to generate friction forces with the moving belt that provide a "speed limiting" function that slows the device from excessive speeds. In a preferred embodiment, the sliding device is shaped as a body board made of foam material having the slide mechanism recessed in a cavity formed within the bottom of the body to keep the rider's hands or feet from contacting the moving belt. The device may also be configured in various other products for sliding like a sled, a ski, or a skateboard.
