The mask that has completely revolutionised the industry thanks to the new and exclusive principles that have been introduced. For the first time in the world, the lenses are not parallel to the face, but inclined and shaped like an "inverted drop", with a very special development whose geometry is protected by a worldwide patent. U. S. Pat. 6272693 b1, the anatomically shaped headband is very thin and not visible when wearing the mask. The view in all directions, but above all downwards, reaches unimaginable levels and exceeds that of a conventional mask by 30%, allowing control of dressing and equipment that is impossible to the big eyes. The inclination of the lenses and the resulting shape of the face piece drastically reduce the internal volume of the mask, which is similar to that of apnea models. The soft silicone edge and wide face flange make the mask very comfortable to wear. Two rotating buckles ensure quick and precise adjustment of the straps. Excellent mask for snorkelling and diving. The alpha ultra dry snorkel has a unique splash guard that prevents water from entering the surface. The end piece has a smooth, ribbed interior that keeps the regulator away from your mouth when snorkelling and diving. A special water collection chamber with a large elliptical valve ensures that the water can be drained quickly and easily.
