FBG 30 Umberto Pelizzari C4 Fibreglass Spearfishing and Freediving Fins
Discover the new FGB 30 UMBERTO PELIZZARI C4 fibreglass fins, the ultimate spearfishing fins that offer the perfect balance of technology, efficiency, and accessibility for all levels of practitioners.
The FBG Umberto Pelizzari fins from C4 are the result of a collaboration between the global icon of freediving and the renowned Italian manufacturer known for its innovation.
Made from pre-impregnated fibreglass, they ensure an even distribution of power across the entire blade.
Their ergonomic 250 C4 foot pocket perfectly hugs the foot, ensuring optimal energy transfer and exceptional comfort even during long sessions.
Thanks to their hardness of 30, they are suitable for powerful divers or those operating in currents, offering maximum responsiveness without sacrificing fluidity of movement.
These fins are ideal for enthusiasts of spearfishing and deep freediving looking for reliable, durable, and high-performance equipment.
WARNING: the FBG 30 UP C4 fins are delivered disassembled, the assembly of the fibreglass blades onto the 250 foot pockets will need to be done upon receipt of your fins.
Advanced Technology & High-Quality Materials
The prepreg fibreglass of the blade ensures consistent performance and excellent durability, even in extreme conditions.
The 3° pre-formed anatomy of the 250 foot pocket makes it particularly comfortable to put on. The thin walls allow the foot pocket to adapt to the shape of the foot without painful pressure points.
Optimal Finning Comfort
The 250 C4 foot pocket perfectly conforms to the foot for a firm hold and reduced muscle fatigue. The polymer used for the 250 foot pocket is particularly elastic and allows for easy and quick donning, thus improving comfort. The internal sole provides a rigid foot pocket underfoot but is flexible on top.
The reduced mass (weight) of the 250 foot pocket minimizes the energy required for movement, allowing the user to achieve notable energy savings and reduced muscle fatigue. The connection between the foot pocket and the blade, thanks to the internal sole, is rigid and solid, transmitting force to the blades with great efficiency.
The system for attaching the blades to foot pockets without rails, already developed by C4 in 2006, allows for elastic flexing of the blade along its entire length.
Hardness 30 & Italian Manufacturing.
Available in several sizes and hardnesses, these fins adapt to all profiles of divers, from leisure to competition. The moulding of all C4 carbon blades has always been done in our production workshop in Italy.
This year, a new department dedicated to the moulding of plastic materials has been created, where the 250 foot pockets as well as the UP, Predator, and Storm blades are now produced directly.
Hydrodynamic Design
The rounded water rails and optimised blade provide smooth gliding and enhanced stability underwater.
The FBG fins feature new water rails with a rounded section that improve water retention on the blade and reduce vortices on the outer edges. The water rails, first introduced by C4 in 1993, have always served to keep water on the areas of the blade that generate reactive thrust.
The FBG fins have an extended thrust surface, which is why the water
