Description
K4 fins have created a unique and new material for windsurfing. OptoFlex is a molded resin long fibre matrix that has been carefully manipulated to provide the perfect flex patterns for windsurfing. Our K4 technicians 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 are extremely robust too -we haven't had a single return through breakage.
THE STUBBY Power Box
Our stiffer and larger area line of fins. Great for heavier riders applying greater power in high wind and wanting more drive in low wind. Also suitable for lighter riders in onshore conditions or for those wanting more 'release' to learn taka's and other wave Free/freestyle moves. Upright template gives better 'pivot' for in the pocket riding.
Flex: LOW
Sizes Available: 16cm, 18 cm and 20cm
