After 30 years of float bags looking the same, you wouldn't expect to find any major innovations in them. Well, enter the world of Jackson Kayak! Paddling without float bags is not a good idea if you ever swim, might swim, ever had a skirt blow, ever might have a skirt blow, or value your kayak. The Fun Float is a single horseshoe shaped bag that goes behind your rear wall to give you a single bag that will stay in, even in the worst swims, filling the entire stern of your kayak. Made of sturdy urethane like the Happy Feet.
