In just a few years the X-Vision has become a benchmark in diving masks. This products success derives from meticulous computer design and numerous optical tests. These results have been confirmed by the many replicas and copies of the product. The central position of the eyes and the optimally angled windows provide the widest possible viewing angle in every direction. Quick-adjusting ergonomic buckles are positioned directly on the skirt: the mask can easily be stowed in a pocket of the BC. Low internal volume and very light weight: only 190g on the surface. Small horizontal ribs between the frame and the skirt in the area around the nose. These ribs absorb and redistribute the pressure exerted by the frame onto the skirt, with a resulting increase in comfort.
