The WEST MARINEShark 3-Person Towable Tubefeatures a tapered gusset that provides better towing characteristics, a more comfortable riding position and easy mounting from the water. The Super Sharks nylon cover is manufactured from 100% 840 denier nylon, giving it twice the tear strength of many of our competitors deck tube covers. Peak performance is guaranteed with the Super Sharks topside neoprene panel, 6 nylon-wrapped handles and neoprene knuckle guards. The durable 70” (deflated) 30-gauge virgin PVC bladder is fully encased by a double-stitched nylon cover with a reinforced internal tow harness. The Super Shark is equipped with a super-convenient Kwik-Connect for easy hook-ups and a patented Speed Safety Valve for fast inflating and deflating. Designed for 1 to 3 riders. Gotta love the unique SHARK Camo graphics!
