29/71 Black Carbon Blades

The 29/71 Black Carbon Blades are precision-crafted fins made from a blend of aerospace-grade carbon fiber sourced from Germany and Japan. Utilizing a revolutionary Resin Infusion process, these blades are exceptionally lightweight while offering outstanding structural strength and mechanical responsiveness.

Each blade contains 9 specialized carbon layers—differing in weight and fiber orientation—strategically arranged to deliver variable flex behavior. This engineering approach enables a soft and relaxed response during light finning and dynamic stiffness when more power is applied, ensuring maximum propulsion with minimum energy loss.

Designed for long ascents and deep dives, the blades reduce muscular fatigue while delivering a responsive feel with every kick. Their unique variable stiffness profile helps divers maintain efficiency at depth or during surface intervals.

Equipped with Cetma Composites S-Wing ergonomic foot pockets and full-length elastic silicone rails, these blades provide enhanced water channeling, comfort, and edge protection.
