Cressi GARA 2000 fins. The first palm in the world to have been made from a unique fusion of three different materials, a process created and patented for Cressi-sub for the launch of this model. Each material is applied to different areas of the fin according to its injunctions in terms of flexibility, hardness, reaction or resistance. In this way, we can assign to each zone the ideal dynamic characteristics it needs without the need to increase the thicknesses and therefore obtain maximum lightness and economy of inertia.
