Set of 2 fins. The Futures Fins, 413 uses the Thermotech fin material. Not only do these fins look great, in fact, in a board they look like a glass on. Most importantly, they feel unbelievably smooth and the performance is incredible. These fins do not have the traditional plastic feel of a composite fin. Instead, they have a very consistent flex that holds well off the bottom then loads up and releases through turns. This is the recommended side fin for all of our Magic boards that have Futures boxes, which includes the Original Magic Model, Mini Magic, Mega Magic, Mini Mega Magic and the Mucho Magic.
