C4 Carbon Fins MB002 Stiffness 25 — Best Carbon Fins for Spearfishing 2024
C4 Carbon Fins MB002 Stiffness 25 represent the most refined interpretation of the traditional carbon fin concept according to C4's philosophy. Part of the MB series, conceived to renew the Italian brand's mid-to-high range of carbon fins, the MB002 were awarded the Best Choice 2024 prize by Apnea Passion magazine as the best carbon fins for spearfishing on the market, an independent recognition that validates their performance, quality and reliability.
Best Choice 2024 Award — Apnea Passion
C4 Carbon Fins MB002 Stiffness 25 won the award for best carbon fins for spearfishing at the 2024 International Awards of Apnea Passion Magazine, the leading specialist publication in the world of freediving. An external and independent endorsement that positions the MB002 as the top option on the market in their category.
T700 Carbon Fiber — Performance and Lightness
The blade of C4 Carbon Fins MB002 Stiffness 25 is made from T700 carbon fiber, the reference standard in high-performance fin construction:
- Extreme lightness that reduces muscle fatigue during extended dives
- Controlled stiffness that precisely transfers the energy of each kick
- High resistance to repeated flexion and marine environment conditions
- Progressive response characteristic of C4's traditional fin philosophy
Stiffness 25+ Soft/Medium
The 25+ Soft/Medium stiffness is the intermediate option in the MB range, positioned between the 20+ ExtraSoft/Soft and the 30+ Medium/Medium Hard versions:
- Optimal balance between flexibility and propulsion, making the most of every kick cycle
- Ideal for intermediate-advanced freedivers with a developed technical kick
- Recommended for spearfishing and freediving in open water and competition
Blade Dimensions and Geometry
- Sizes 36/37 to 41/42: blade dimensions 874×195 mm
- Size 42/43: blade dimensions 980×195 mm
The wide propulsion surface maximizes hydrodynamic performance with each kick, maintaining a manageable and balanced profile.
Rounded Section Water Rails
The rounded section water rails in black channel the water flow along the blade during the kick, improving hydrodynamic efficiency and stabilizing the fin's trajectory. Their rounded section smooths the water transition and contributes to a more fluid and natural kick.
C4 250 Footpocket with 3° Preformed Angle
The C4 250 footpocket included in C4 Carbon Fins MB002 Stiffness 25 incorporates a 3° preformed angle, which optimizes foot position during the kick and improves energy transfer from the leg to the blade. Also compatible with:
- All carbon blades in the MB series
- UP (Umberto Pelizzari) Technopolymer Blades
