The strength comes from the internal frame (subframe) molded directly beneath the surface of the silicone rubber skirt (patent pending). This subframe provides incredible strength and rigidity as well as eliminating the bulky external plastic frame in other masks. A stainless steel retainer locks the lenses in place and provides added strength to the nose bridge area of the mask. A wide field of view and great fit completes the combination of function, style and durability. ARC Coatings Atomic Aquatics developed ARC (Anti-Reflective Coating) technology to reduce reflected light and actually increase the amount of available light transmitted to a diver’s eyes. The result is a greatly improved transmission of 98% of available light, compared to a loss of more than 14% of light with standard green "float" glass used on the majority of masks on the market.
