The SONIC SUP race fin is designed for blistering speed, enhanced flow and ultimate control especially in ocean and river conditions. The Sonic is highly recommended for beach/surf races and downwind SUP racing.
The Sonic is best suited for advanced to professional stand up paddlers with a high cadence and has quickly become the fin of choice for many elite and professional SUP racers. Built in our ultralight Pro Carbon construction our fins are the lightest SUP race fins available.
