Cressi Adult high-end Scuba Diving mask. Made in The Revolutionary Crystal Silicone. Big Eyes Evolution Crystal.
Absolute transparent that provides a great interior lightning, fabulous aesthetics both as product and on the diver’s face (especially in underwater photography).
Reduced tendency to yellowing over time, 90% less than other types of silicone due to its unique chemical composition.
Silicone free of silicon chloride, a component that causes the traditional and cumbersome greasing of the crystals after the assembly of the mask and that must be removed to get a correct use of the mask.
