Seeing really is believing!
Each Atomic mask has been specifically designed and engineered to always perform its best for any diving situation. Atomic masks feature the highest quality UltraClear glass lenses available, squeeze to adjust buckles, and super soft silicone skirts for added diver comfort. The Atomic SubFrame mask is so durable, it carries a Lifetime Warranty against frame breakage. The strength comes from the internal frame (sub frame) molded directly beneath the surface of the silicone rubber skirt (patented). The subframe provides incredible strength and rigidity as well as eliminating the bulky external plastic frame in other masks. A stainless steel retainer locks the lenses in place and provides added strength to the nose bridge area of the mask. A wide field of view and great fit completes the combination of function, style and durability.
Medium fit is designed for a perfect fit for divers with narrow faces.
