The Zeus is the perfect mask for diving. This mask has a particular tapered structure deriving directly from the highly popular Nano-mask patent. The same IDF-INTEGRATED DUAL FRAME TECHNOLOGY SYSTEM allows you to join the silicone skirt to the lens frame without major interruptions of the curvature continuity. The result is a mask with an extremely hydrodynamic shape and, visibility being equal, a significantly smaller size. The field of view obtained is particularly wide, laterally and in the lower zone. Thanks to its matte coating the mask components all match, enhancing the underwater experience since it prevents reflections in the water that may disturb marine life.
