World of Watersports' original 1-person, partially covered tube was changed up a bit with a new arrow-shaped design rather than a circular one. This new design allows for more stability and control for the rider. Double webbing foam handles with knuckle guards. Flat foam handles. Reinforced towing system. Speed valve for fast inflation/deflation. Drain vent prevents excess water buildup. Note: For faster connection times, Overton's recommends purchasing the Tow Rope Connector (item #321132). 50" x 48" | Wow Sports WOW Ace Racing 1-Person Towable Tube | The House
