Youve ridden these classic "banana" inflatables at beach resorts, having the time of your life; now its time to actually own a commercial grade BIG DOG. All seams are hot air overlap welded to increase durability. The double reinforced tow harness is equipped with two 316 stainless steel rings and a 316 stainless swivel to prevent twisting and damage to the tow rope. Theyre constructed of UV resistant 31 oz. 1000 denier polyester mesh reinforced PVC and equipped with double reinforced seat pads, heavy duty handles with knuckle guards and 3 H style valves. A carry bag and a foot pump for inflating and deflating are included.
