Designed for maximum protection when rafting or tying up against solid walls, this unique rectangular cushion has six molded tubes that provide crush resistance. Exclusive channels let these cushions hug the boat. Made from tough marine-grade vinyl with an inflation valve for air pressure adjustment. Rafting cushions may be hung vertically or horizontally. They also make great piling cushions and are very comfortable to sit on. Caution: Never use rafting cushions as a life saving device.
