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

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.
