K4 worked hard to design a fin that could be both fast and also turn.
3SW offers a combination that no other fin can. The template, and outline, of the 3SW combined with our revolutionary K4 Super Stiff material makes for unrivalled performance. In bump and jump conditions you have speed and control. In down the line conditions you have grip and carve. Used in the RRD FSW board the K4 3SW is a truly great fin and will perform in any conditions.
Developed with help from the Official Test Centre Weymouth. A fin that will give you amazing speed and control, secure and loose carving on the fast flats or choppy waves. The material is K4’s ‘Super Stiff’, the ideal composite for freestyle-wave fins; great reflex, stiff enough for excellent acceleration and direct response, enough flex for speed, grip and control. The 3SW also works great in big wave boards.
