With the same UltraClear lenses and wide view lenses of the Atomic Aquatics Frameless Mask, this upgraded version uses a different construction of silicone on the mask skirt to improve the already comfortable fit of the scuba mask. Two grades of silicone are molded together to create a comfortable mask skirt. A special sealing flange is co-molded with a softer grade of silicone for a softer feel against your skin. The Frameless 2 has distortion-free UltraClear lenses. They offer maximum optical quality and a wide field of view. The hydrodynamic design and compact shape cut through the water. This delivers optimal movement in small spaces. Soft silicone sealing flange for maximum comfort Distortion-free UltraClear lenses for wide vision and an extraordinary view Streamlined design for unparalleled comfort Squeeze-to-adjust buckles for a custom fit Tempered, optical-quality glass lenses Durable and resistant to breakage
