Introducing the Big Sun 9' Inch Upright. Perfect for our transition era Big Midlengths and other Single Fin models. This fin is super fast, with a narrow base and a narrow tip for a minimal amount of surface area. The tip incorporates elements of flex which will whip you out of fast turns.
Big Sun fins are of the highest quality, hand foiled using the best materials. We have brass pin details and tool-less screws.
