Sometimes you see them. Struggling against the wind, out of breath and paddling hard, but going nowhere. The Roll-Up Sail allows stand up paddlers to sail when there's wind. You can even go upwind. When the wind dies down, simply roll it up and use the paddle as you normally would. The Roll-Up Sail is the perfect way to make every SUP outing fun. *Paddle not included* http://www.youtube.com/watch?v=PxVT7mOQ_rI
