Dual Tab The Skindog Single Fin, available in 7" and the new 8" size, is designed to deliver a powerful yet fluid feel, perfect for harnessing speed and control in bigger surf. Paired with the Skindog Sidebites, these fins create a 2 + 1 setup that enhances drive, stability, and maneuverability. The sidebites add speed and control, allowing surfers to handle critical sections and maintain stability through sweeping turns. Together, the setup offers a dynamic and versatile longboard experience, ideal for both traditional and progressive surfing styles. Both the Skindog Single Fin and Sidebites feature Performance Core (PC) construction with innovative AirCore technology. This design incorporates a pressed polyurethane foam core that mimics the geometric foil of the fin, reducing the amount of fiberglass needed in the resin transfer molding (RTM) process. The result is a significantly lighter fin with precise flex characteristics. AirCore technology allows for total manipulation of the flex, enhancing responsiveness and control, while maintaining durability and high performance across a variety of wave conditions. Two Quad Rear Sidebite fins designed to add speed, stability and control to any 2 + 1 set up.
