This revolutionary mask is made of High Seal Silicone, a material that offers extraordinary and unprecedented comfort.The raked lenses, with their inverted drop shape (Cressi patent), are quite small and brought close to the pupils as possible, so that the already extraordinary visibility of the Matrix is increased by 25%. The frame uses the exclusive patented Cressi system of double injection of an elastomer on a rigid element. This technology allows the buckles to be mounted not on the skirt structure, as done by our competitors, but on an indestructible elastic element that allows the buckles to tilt and turn completely without breaks. The thickness of the frame has been reduced to such an extent as to make it practically invisible when the mask is being worn. The Big Eyes Evolution comes with a reusable hard plastic case to protect it during travel and to store it when unused. The Big Eyes Evolution is designed and made in Italy by Cressi, a brand pioneer in scuba diving, snorkeling and freediving equipment since 1946. The product is covered by a 2-year limited warranty.
