A tapered, high-quality elastomer blade that facilitates excellent agility and performance. This high-performing fin offers variable thickness and increased maneuverability without sacrificing the length and strength of the fin's blade. An excellent choice for freedivers looking for a more rigid and reactive fin.

The innovative Razor Pro fins deliver the best performance among all technopolymer fins currently on the market. They are a benchmark for the most demanding freedivers and spearfishermen.

The Avanti Quattro Power uses Mares' four-channel patent. The deformation achieved when the blade is optimally channeled creates a significant flow of water and increases thrust.
