Float the river in comfort and style with the Sevylor 54" Mesh River Tube. The Mesh River Tube is durably constructed of 14-gauge nylon and measures 54" across. Its comfortable mesh seat keeps you cool in the water while the inflatable back rest provides support while you relax. There's a convenient built-in cup holder. Two handles and an all-around grabline provide easy access. The River Tube inflates and deflates quickly thanks to Sevylor's Double Lock Valve and carries the Air Tight Guarantee -- so it's guaranteed not to leak. The Park 'N' Play System lets you connect other Sevylor inflatables together on the water.
