It's time to unleash the Fury! This snow tube is built extra tough featuring a heavy-duty partial nylon cover, double-webbing foam handles with knuckle pads, and a slick molded Hard-Body bottom. The special Hard-Body molded PE bottom surface not only makes this tube glide over the occasional piece of debris or exposed ground without harm to the tube, but also makes for the fastest possible inflatable sled you can buy. It's the perfect combination of disk sled fun and speed with air cushioned comfort
