Fiberglass Fin Blade with 60cm in length
Fiberglass blades bend and snap back smoothly.
This creates an efficient “spring effect” — the blade stores energy during the kick and releases it on the return, propelling the diver forward with less effort.
Compared to plastic, they’re much more responsive.
Blade Angle
The 20° blade angle matches the ergonomics of the ankle + hydrodynamic efficiency, so you get maximum thrust with minimal effort — which is exactly what a freediver wants for energy conservation.
Rails or Ribs
Color of rails or ribs are already fixed and cannot be changed anymore. If in case you want other rail colors this is upon request and and will take around 1-2 weeks availability. Colors available: Black, White, Red, Pink, Blue.
