The Bestway Hardcore Rapid Rider tube is designed to fit an adult. Sturdy 18 gauge vinyl construction fits adults up to 350 lbs. It’s great for floating down the river or relaxing in the pool. The mesh bottom keeps you cool while the built-in inflatable backrest provides support. The tube features a pair of cup holders to keep drinks at the ready. The heavy duty handles and the all-around grab rope make it easy to mount from the water.
