The "rescue tube" is usually made of vinyl, and is buoyant enough to support the full weight of a rescuer and several victims. The tube has a long leash that the lifeguard wears around the body to tow the tube along while swimming a long distance. The rescue tube is usually red, but can come of a variety of colors. Rescue tubes often have the words "Guard" or "Lifeguard" printed on them. The tube may also have clips, so that it may be wrapped around a person.
