All our fins are produced in handmade pre-preg technology. This is the only way to get the best performance next to the smallest tolerances. not a secret that sometimes two similar fins can feel different, but this gives you the opportunity to test out the best one that is the fastest for you.



Our fins come in two different type of boxes: Tuttle and Deep Tuttle. By default all fins from 28 to 42cm are made with tuttle box, and from 43cm and up, deep tuttle is used. Smaller fins can also be delivered with deep tuttle box if you board supports it.


Slalom fins are available in sizes from 28 to 52cm


First three letters – The model ZSL, ZSF, SLM
Next two numbers – Length in CM
Then follows stiffness and type of fin head.
For example: ZSF 38 S- Tuttle. This is the ZSF model blade, length 38, stiffness extra soft, tuttle head


Warranty for S and S- fins lasts 12 months. For S– fins, the warranty is 6 months starting 10 days after fin is shipped from production.


Due to big tolerances in board production, we are producing the fin head 1/10mm bigger than the fin box. This means, that the first time you are using your fin, you might need to sand the fin head until it fits correctly into the box. If you sand it too little and start tightening the screws, you might break the fin head, and this is not covered by the 1y or 6m warranty.
