This Air mask has a particular tapered structure deriving directly from the highly popular Cressi Nano mask patent. The Dual Integrated Frame Technology System (Cressi patented US 20140013494 A1) allows you to join the silicone skirt to the lens frame without major interruptions of the curvature continuity. The result is a mask with an extremely hydrodynamic shape and, visibility being equal, a significantly smaller size. The mask features inclined and inverted tear-drop lenses for improving downward visibility, a Cressi patented design (US 6272693). The field of view obtained is particularly wide, laterally and in the lower zone. The lenses are made of tempered glass. The buckles are integrated with the frame with a swivel system that are easy-to-use for quick strap length adjustment. This technology is patented by Cressi (US 8281417 B2). The Air mask is available in black silicone or in Crystal Silicone™ for high visibility and long lasting use. The skirt made with top quality Crystal Silicone™ is a Cressi trademark formula to avoid yellowing after years. In the front part, the skirt has a structural silicone insert which increases the sealing ability of the mask and creates an exceptionally pleasant chromatic play. The mask comes with a protective plastic PVC case. We recommend to use an anti-fog solution for clean the lenses before the first use. Rinse with clear water after use and let it dry away from direct sunlight.
