Product Details
Many hours of research and development went into designing a fin that could be fast and also turn well at the same time. The 3SW offers a combination that no other fin can do. The shape and outline of the 3SW combined with the revolutionary K4 Super Stiff material make this fin unparalleled performance. In bump-n-jump conditions you have both speed and control. In wave conditions you have both grip and carve. Used by board brands for their FSW models, the K4 3SW is a truly exceptional fin and performs excellently in all conditions.
The K4 fins are a unique product in the windsurfing world, they are made using highly engineered composite polymers with maximum load of high modulus fibers. The performance of these fins is exceptional in terms of flex, reflex, lightness and damage resistance. Compared to the classic G10 fins, these fins are lighter and have a superior reflex.
