    RRD K4 3SW

    Freestyle wave windsurf fin, the latest offering from K4 Superb performance and a great price what more could you want.

    Available in POWER BOX only - As Supplied with 2019 RRD FSW boards.

    Our new freestyle 3SW windsurfing fins use only our new super stiff material and give incredible speed, maneuverability and acceleration that will adapt to waves, freestyle or bump and jump.

    Our perfect flex pattern gives you lively and grippy performance. These fins feel solid under your feet but have enough flex for looseness and bite through the turns.

    K4 Fins have created a unique and new material for windsurfing called OptoFlex. This is a molded long fibre resin matrix that has been carefully manipulated to provide the perfect flex patterns for windsurfing. It took a long time to create the perfect material with the qualities needed to provide the performance we now appreciate. Lighter, snappier and with outstanding flex memory. The fins have been testing the highest grade materials in the lab and on the water for nearly two years, continually improving the aesthetics and the performance.

    Pro Riders such as Graham Ezzy, Jamie Hancock and Mikey Clancy have chosen the fins out of preference and the team is likely to grow as word continues to spread, these Pro level fins are now available to you from Boardwise.
