With the Reaction, Cressi benefits from its many years of experience in the development and manufacturing of high-quality fins. Made from three different materials, the Reaction offers high propulsion and precise water guidance for all types of divers and diving activities. Innovative features include the fin blade that starts at the foot, side stabilizers, a non-slip sole, and the Cressi EBS bungee. The result is a perfect fin for all divers who prefer a stiffer blade. With its exceptionally high propulsion, it can also handle critical situations with strong currents safely.
