Cressi Prisma Negative Prescription Dive Mask The Prisma is not just a mask; it’s a reliable companion for exploring the underwater world in crystal-clear vision. Equipped with Cressi’s patented FOG-STOP system, it drastically reduces fogging by regulating the warm, damp air exiting the nose through internal thermoregulation. The external skirt also features a cooling system made of soft heat exchangers that act as radiators, effectively lowering the mask’s temperature and preventing fogging by trapping humidity droplets before they reach the lenses. What sets the Prisma apart is its exceptional ease of adjustment. The micro-adjustment buckle is connected to a soft connection point at the frame, ensuring a smooth and hassle-free adjustment of the strap tension without causing any deformation of the skirt, which can lead to water ingress. The combination of two different frame materials and Cressi’s innovative patented soft skirt construction makes the mask fold effortlessly, fitting comfortably in your BCD or cargo pocket. The Prisma offers the versatility to accommodate optical lenses for both negative and positive correction, ensuring that everyone can fully immerse themselves in the wonders of the underwater world without compromising their vision.
