Extends the lifespan of your river float tube. River guides pair this product with Intex river tubes to produce top-of-the-line river tubes! Enables use of Quick Connect rope-clip systems for linking your Intex tube together. Sturdy construction designed for river guides. 57" diameter cover allows for full inflation of the Intex river run tube you insert, even after prolonged exposure to the sun. Measures around 50 inches in width when inflated. 1000 denier micro mesh bottom allows water to pass through while offering exceptional protection against abrasion from rocks, tree branches, and other debris. Durable 1100 denier coated canvas top is comparable to the material of a whitewater raft. Caution: Make sure to fully inflate Intex River Run Tube inside cover until both tube and cover are firm and all excess slack is eliminated. Under inflating your tube will result in poor performance in the river.
