Pull behind a boat or use as floatation in summer; and/or tow behind an ATV or snowmobile, or slid down a hill in winter. These THICK RUBBER implement tubes are VERY durable and versatile and will provide months of fun every year. I have 4 tubes and depending on which one you choose they inflate to at least 3 1/2 , 4 1/2 or 5 1/2 to 6 feet or more across. Prices range from $40 to $95, and all tubes are in EXCELLENT condition. Tubes only, no covers
