A classic in the Cressi range, this has been on the market for many years and has a huge number of appreciators in every corner of the planet. The ?n is made with a skillful combination of a strong copolymer and a soft elastomer, the latter used for the foot pocket, for the side stringers and for some inserts. The blade originates from the upper part of the foot pocket, with a 20% increase in useful surface area compared to a traditional ?n of the same length. The foot pocket is computer designed and offers great comfort; it guarantees excellent transmission of the leg-?n thrust. The Frog is heavier than the more recently designed equivalent Cressi models. It is this feature that makes it agreeable to whoever uses very thick wet or dry suits. Anyone who works underwater will appreciate this ?n because it is strong and comfortable, also very popular in diving schools and excellent for rentals. The fin straps are equipped with easy to adjust quick-release buckles. The strap is also equipped with a large heel pull tab for easy donning and doffing. Fin is available in multiple sizes.
