Atomic Aquatics Arc SubFrame Mask combines durability with clear underwater visibility for scuba and diving gear. Its internal subframe is molded directly beneath the surface of the silicone rubber, creating a two-window design with high strength and a low-profile fit for comfortable wear during long dives.Hydrodynamic styling with no exposed external frame reduces drag, while squeeze-to-adjust buckles simplify fit changes underwater. The mask uses UltraClear lenses with optical quality and distortion-free performance, and comes with a choice of clear or black silicone rubber with co-molded color accents. Lenses are removable for corrective options, and ARC technology lenses are available for enhanced underwater vision. Available in a variety of colors to match your style in the water gear collection.
