Big River TubeWith an extended center to center compartment, the NRS Big River Float Tube provides the same fun as the Wild River Tube with more room and greater buoyancy for larger river rats. Tough PVC inner bladder inflates and deflates through a reliable Leafield C7 valve. Super durable, urethane coated polyester reinforces the bottom of the tube for extra protection in shallower waters. Protective flap covers the single valve and secures with a hook and loop
