A compact, round ski tube, the Connelly Mach 1 One-Person Ski Tube is designed with a segmented bottom hull, meaning there's less surface area. This reduces drag and lets you reach phenomenal speeds. This flat tube is sized for a single rider lying flat with two padded handles (with knuckle guards) to let you hang on tight. A heavy-duty PVC bladder keeps the tube afloat, covered with soft 420D nylon. The bladder inflates quickly thanks to a Boston valve while a mesh bottom drains excess water away. A patch peel-and-stick repair kit is included. This trio of high-intensity brands designs, manufactures, and uses the best equipment on the water. With state-of-the-art boards and skis made using the latest technology and materials, the best gear and accessories anywhere, and a stable of enviable professional sponsorships, they just can't be beat. When you're heading out to the lake, make sure you're riding with the best. Dimensions: 58 diam. in.. Buoyant bladder covered by 420D nylon. Designed as a single-rider craft. 2 padded handles keep you on board. Includes a repair kit for minor tears.
