Sportstuff Sumo & Splash Guard Combo: This single chamber tube is made of 100% heavy-duty K80 PVC with radio frequency (RF) welded seams and is put over the rider like a shirt, instead of being directly attached to the boat. Take it to the beach for the ultimate body surfing experience, or grab two Sumo's and have a Sumo wrestling match with a friend!
