Our patented injection molded composite single fin is a functional and versatile single fin unlike anything you've ever ridden.  Our published research shows this fin holds better, is more maneuverable, and gives longer and faster rides than a standard fin. And, the bigger the wave, the better! Flow Tech adds stability and drive with excellent control.  Made from a durable and proprietary composite blend, it fits all single fin boxes.
