The Atomic Ultra clear Sub Frame mask is the strongest and most indestructible two window mask ever made. The Atomic Ultra clear Sub Frame mask is a two window design built with an innovative patent pending three piece frame structure. This structure provides unparalleled durability and strength. In fact, the Atomic Sub Frame is so durable that Atomic offers a LIFETIME WARRANTY against frame breakage.

To add even more rigidity and strength to the frame structure, Atomic engineers designed into the frame a solid 316 stainless steel Lens retainer support section around the nose bridge. This makes this the Atomic Ultra clear Sub Frame mask incredibly rigid in the normally weak area of a two window mask design. The support is not just a metal accent, but a purposefully designed structural support to keep the lenses flat and parallel to the viewing plane.

The Atomic Ultra clear Sub Frame mask offers a new standard feature never seen or seen before on a diving mask. They call them ULTRACLEAR lenses. What makes ULTRACLEAR special? Did you ever notice that normal dive mask lenses have green tint to the glass? To see this tint put you’re existing mask up to a piece of white paper and see for yourself. The green tint you see is the result of iron impurities left over in lower quality glass. That green tint distorts true colors and blocks out some of the light that reaches the eye. The Ultraclear glass in the Atomic Ultra clear Sub Frame mask is a new and exciting optical quality glass with exceptional clarity and high light transmission, with no color distortion.

As with most things in life there is some care for your new mask, you will need to clean off the inside of the lens before you can dive it!
