The Sportsstuff Big Bertha Towable Tube is built for big fun on the water with space for up to four riders to enjoy the ride. Designed for boating and watersports, this oversized tube delivers exciting action whether cruising across the lake or bouncing through boat wakes. Its durable construction combines a tough inflatable base with a partially covered nylon top for added comfort and strength during high energy rides. Foam filled handles wrapped in nylon provide a comfortable grip so riders can hold on tight as the action picks up. The quick connect tow system makes attaching the rope simple and fast, getting riders back on the water in seconds. With a patented speed safety valve for easy inflation and deflation, this tube is ready to keep the fun going all summer long.
