When you learned how to dive your instructor told you the most important part of choosing equipment was comfort and fit. When looking for a mask you also need a great field of vision well this mask was designed to meet those and more desirable qualities. The Sub-Frame Two-Windowed Mask is a low volume mask which offers you a wide field of vision and because of its frame design is one of the most durable masks found on the market today. This durability has been achieved with a Sub-Frame that is molded and bonded directly to the mask's silicone rubber skirt. A second frame made of corrosion resistant 316-grade stainless steel protects the nose bridge area and adds strength and ultimate durability. Mask has optical quality glass lenses and squeeze-to-adjust buckles.

The Atomic Sub-Frame Mask offers a new standard feature never seen or seen through before in a diving mask. Atomic calls them Ultra-Clear lenses. What makes Ultra-Clear special? Did you ever notice that normal dive mask lenses have a green tint to the glass? To see this tint, put your 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 float or window type glass. That green tint distorts true colors and blocks out some of the light that reaches the eye. UltraClear is a new and exciting optical quality glass with exceptional clarity and high light transmission, with no color distortion. The exceptionally high light transmittance and lack of distortion in the UltraClear lens maximizes the light available for improved visual acuity, especially underwater in low light conditions, better vision, truer colors are what you get with Atomic Aquatics ultra-clear lenses. If you need to use corrective lenses the Atomic Aquatics Sub-Frame Mask has optional corrective lenses available (see SKU: ATMMLSFL10).

The Atomic Aquatics Sub-Frame Mask has a double feathered edge skirt that provides an excellent seal on the diver's face with an easy-to-reach one-handed nose well for ear equalization. The wide split style mask strap increases the mask's ability to conform to your face adding to its great sealing ability. The Mask is available in multiple sizes to fit most divers' faces. The Sub-Frame Mask comes in multiple color choices. The Atomic Sub-Frame Mask comes with a mask box for transport and storage.
