29/71 Blue Carbon Fins

The 29/71 Blue Carbon Fins are crafted from 100% aerospace-grade carbon fiber sourced from Germany and Japan. Using a proprietary Resin Infusion process, the blades are formed under 30 hours of vacuum compression—delivering extremely lightweight yet structurally robust fins.

This process eliminates excess resin and produces unmatched mechanical performance. The carbon material is printed before resin infusion, locking in a one-of-a-kind blue aesthetic that stays vibrant underwater.

Each blade incorporates nine layers of carbon fiber, precisely arranged with varying weights and orientations. This results in a responsive variable flex profile—soft during light finning and dynamically stiffer under force, maximizing efficiency while minimizing fatigue.

Paired with Cetma Composites S-Wing or 29/71 DS.1 foot pockets for ergonomic support and with full-length elastic silicone rails to improve hydrodynamics and blade protection. Ideal for recreational and advanced freediving alike.
