The Atomic Aquatics Frameless Mask is focused on fit, comfort and a wide vision field. The large lens and close fitting skirt work in harmony to create perhaps the widest viewing angle of any frameless mask design. The lens shape was computer designed to maximize upward, downward and side to side vision. Because an external frame is not needed, the viewable area of the lens is optimized. Squeeze-to-adjust buckles are tucked behind the lens for a sleek hydrodynamic design.
