Matrix V-2 towable tube from Airhead. U-shaped winged towables roll way up on edge when riders shift their weight. The wings also make them a joy to tow, they slide effortlessly across wakes. No expense was spared in Matrix's state-of-the-art construction. They're thicker at the front to prevent submarining and thin at the back to make it easier to climb on from the water. The deluxe handles have neoprene knuckle guards. Two oversized neoprene pads are strategically located to protect knees and elbows. The durable 30 gauge RF welded PVC bladder is completely wrapped in double-stitched 840-denier nylon. A heavy-duty Kwik-Connect provides easy hook-ups and the Boston valve makes it easy and fast to deflate and inflate.
