Originally designed for commercial tubing parks, this Flexible Flyer hard plastic-bottomed snow tube offers the cushion of a winter tube with the speed of a fast plastic sled. It features a heavy duty, hard shell plastic bottom to prevent punctures. The thick black rubber inner tube and 1000 denier Cordura nylon cover withstand rugged conditions. Hammock web straps provide even support while the cushioned inflatable sled tube absorbs bumps, providing a much smoother ride than hard plastic snow sliders. The slick-coated hard-shell base provides an ultra-smooth sliding surface that makes this sledding inner tube glide over snow. For even more speed, apply a light coat of wax. The black inner tube has a Schrader valve that inflates just like car tires. The built-in tow strap make it easy to carry and pull back up the hill. A kids and adult snow tube, heavy duty conditions are where it thrives! A snow sled for adults and kids age 5 and up. Measures 42 x 42 x 11 inches and weighs 8 lbs. Since 1889, Flexible Flyer has been producing sleds. We stand behind our products 100%.
