29/71 B-Spec Carbon Fins

High quality 100% pure carbon fins from 29/71.

This is the entry level carbon fins model from 29/71, specifically designed for beginner freedivers.

Made with a combination of German and Japanese produced aerospace grade carbon fiber.

Produced using an innovative Resin Infusion process, allowing the lightest possible blades.

Unlike the traditional production method of Wet Lay up and mechanical press, Resin Infused blades are compressed prior to the introduction of resin. Each blade spends 30 hours under constant vacuum during production, this technique immensely improves the mechanical properties of the blades and results in superior mechanical and structural performance.

Each blade features 9 layers of different weights and fiber directions, giving the blades an ergonomic, variable flex which is ideal for long ascents while exerting minimal strain on the divers leg musculature.

The blade’s unique structural design was pioneered by 29/71 to allow the blades to be soft when finning with minimal effort and stiffen up once greater force is applied, the stiffness of the blades essentially varies in reaction to the energy applied by the diver and virtually eliminates energy loss.

Equipped with Cetma Composites S-Wing ergonomic foot pockets and full length elastic silicone railing which aids in water channeling over the blade and minimizes any resistance of the blade which is common with traditional rubber railing.
