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.
