Big Eyes Evolution Crystal Mask - Scuba mask, Snorkelling mask

Silicone crystal, an incredible new frontier in the world of transparency. It is long-lasting and won't turn yellow, and thanks to its special chemical composition it drastically reduces the irritating effect of lens fogging. An absolute cressi exclusive. Evolution skirt: to obtain a similar result, double injection technology was used to create the structure of the skirt. This technology is a new dual-injection system that can differentiate the stiffness of the skirt at each point, making it stiffer where needed for a crush-proof structure, and softer where the most comfort is required. The angled lenses, moved as near to the eyes as possible, have increased the matrix's already incredible view by 25%. The ring capitalizes on cressi's exclusive patented dual-injection of an elastomer onto a rigid element, which makes it possible to avoid mounting the strap buckles on the structure of the skirt like the competition. Instead, they are mounted on a flexible and indestructible element that pivots on a vertical plane and can be folded completely sideways over 180¡. The ring is thinner, in fact even thin enough to disappear completely from view when you wear the mask. Tempered glass lenses. Option for graduated corrective lenses from -1 to -6 diopters, including half diopters
