Combining hydrodynamic design with top-shelf lense technology, the Atomic Aquatics Venom Arc mask provides superlative vision under the water?s surface. UltraClear Schott Superwite? glass lenses offer wide-angle peripheral clarity while the double-layer silicone skirt holds the mask firmly in place. Building on the original Venom, the Arc includes an Anti-Reflective Coating (ARC) that?s applied to both sides of the UltraClear lenses, reducing glare and allowing more light to reach your retina. An innovative squeeze-to-adjust strap allows for rapid fixes in the water. And if it ever breaks, no worries?the Arc?s frame is covered by a lifetime warranty.
