WOW's most exciting towable yet! Built for 1-3 riders, the XO Extreme is a one of a kind, oval shaped design towable with a rockered bottom to provide the most excitement ever on the water! Because of its patented oval shape design the amount of surface area touching the water Is minimal which allows for a fast ride and less drag on your boat (i.e. better gas mileage) as it slips and slides across the wake with ease. XO Extreme has high profile and is highly visible in the water. It also makes for a great lounger, so after your thrilling ride sit back. relax, and float.
