Select options Cressi Fast Suits Ladies 5mm $349.00 The anatomy of the cut of the pants is preformed to improve flexibility for an easier finning. FAST combines a single 5 mm piece (also available in 3 and 7 mm versions) with a separate 5 mm and 3.5 mm cap, very elastic coating. The three elements can be purchased separately. It is particularly comfortable to wear and modular thanks to the new double lined neoprene sleeves, with a “Seal” inner ring to ensure a watertight seal. This solution provides durability and is also guaranteed for dive centers that use it as the school and equipment rental for optimal results. YKK® rear zipper has the Acquastop® sealing system with smooth neoprene and internal under zipper to minimize water infiltration. The neck closure has a significant design improvement that reduces water ingress at this critical point. The closure flap is now much wider and longer to prevent infiltration when tilting the neck under water. Anatomically designed neck, preformed at 120º for maximum comfort. Knee area and shoulder straps with Tatex® wear-resistant elastic reinforcements.
