Atomic Aquatics Venom Mask is a blending of Atomics SubFrame and Frameless Masks. It has a reinforcing internal frame that’s molded directly beneath the surface of the silicone rubber skirt, like on the Subframe, yet it offers the relatively low profile of the Frameless. A single window like the Atomic Frameless, but it has a high bridge and tear-drop shape similar to the SubFrame’s dual-window design. Its easy-to-use squeeze-to-adjust buckles are soft-mounted to the mask skirt, which allows flexibility in strap positioning, plus they can be folded flat for packing.___ Where the Venom differs from its SubFrame and Frameless cousins is in its lens construction. While the SubFrame and Frameless lenses use Ultraclear glass, which has a reputation for optical quality in its own right, on the Venom mask Atomic uses an even higher-quality glass imported from Germany. Called Schott Superwhite glass, it allows more light to penetrate than even Ultraclear glass.___ As with all Atomic Aquatic Masks the Venom has a double feathered edge silicone rubber skirt with a wide split strap design, which in combination, afford an excellent fit and seal on the face. A one-handed nose well for easy ear equalization brings the lens of the mask closer to the diver’s face further increasing the field of vision. The Venom comes with a mask box has a limited lifetime warranty on the frame and a 12 month limited warranty on the buckles and mask skirt.
