The Atomic SubFrame Medium Mask is a durable two-window mask built with Atomics UltraClear lenses. The SubFrame Medium Mask offers superior clarity and field of vision that is hard to find in any other mask on the market. Its soft silicone skirt provides a great fit and reduces face fatigue, making this mask a perfect combination of comfort, function, and durability.

The SubFrame Medium Mask is Atomics strongest and most durable two-window mask. Featuring a lifetime warranty against breakage, the SubFrames internal frame is molded directly beneath the surface of the silicone rubber skirt. This adds strength and rigidity and eliminates the bulky external plastic frame of most masks. In addition, a stainless steel retainer locks the lenses in place. This adds strength to the nose bridge.

Many lenses have a green tint resulting from iron impurities left over in lower quality glass. This green tint distorts colors and blocks out some light. The SubFrame features UltraClear lenses with higher optical quality glass, resulting in exceptional clarity, better light transmission and no color distortion.
