C4 - Πτερύγια FBG Umberto Pelizzari

Innovation, experience and passion for freediving

From the collaboration with Umberto Pelizzari, a global freediving icon, and backed by over thirty years of experience in designing high-performance fins, the new FBG Umberto Pelizzari line is born.
Entirely designed and manufactured by C4, these fins represent a perfect balance of technology, efficiency and accessibility.

Technology and materials

The FBG Umberto Pelizzari fins are made with 100% fiberglass blades, laminated using the same structure as our top carbon models.
They are paired with the innovative C4 250 foot pockets to ensure top-level comfort and energy transfer.
The result? High and long-lasting performance with an exceptional quality-to-price ratio.

Available in 3 stiffness levels to suit every need:

• 20 Soft: maximum sensitivity for dynamic freediving and technical training.
• 25 Medium: the perfect balance between freediving and spearfishing, maximum versatility.
• 30 Hard: designed for intense spearfishing, provides powerful and responsive thrust.

Why choose FBG Umberto Pelizzari fins?

✔ 100% fiberglass blades with advanced layering
✔ 250 foot pockets for a comfortable and secure fit
✔ Designed to meet the needs of freedivers and spearfishers
✔ High performance at a competitive price
✔ Suitable for all levels, from beginner to expert

The pre-shaped 3° anatomy of the 250 foot pocket ensures a very comfortable fit. The thin walls allow the upper part of the foot pocket to conform naturally to the shape of the foot without painful pressure points.

The polymer used for the 250 foot pocket is especially elastic, making it easy to wear and enhancing comfort. The inner sole gives the pocket a firm base while maintaining a soft and flexible upper.

The FBG fins are equipped with new rounde

d-section water rails, which improve water containment on the blade and reduce vortex formation on the outer edges. First introduced by C4 in 1993, water rails are designed to retain water over the blade areas that generate reactive thrust. The FBG blades feature an extended thrust surface, which is why the water rails are continuous from the foot pocket to the tip of the blade.

All C4 carbon and fiberglass blades have always been molded in-house at our production facility in Italy.
This year, a new department for plastic molding has been established, where the 250 foot pockets, along with the UP, Predator, and Storm blades, are now directly produced.
