The Naxos mask is compact and smaller than a classic dive mask, but this unique feature does not reduce the field of vision, and thanks to new internal ribs, it adapts perfectly to any anatomy of the face. Naxos, like Quantum, not only offers increased downward vision but also avoids the phenomenon of fogging by thermoregulating the warm, moist air that escapes through the nose inside the mask. This is channelled by a system of membranes in the mould around the eyes and nose, which deflect the flow towards the rubber walls and not towards the glass. On the outside of the walls is a cooling system consisting of two small heat exchangers that function like radiators. The effect is that the temperature inside the mask is lowered, bringing it closer to the outside temperature, and that moisture droplets are trapped before the air reaches the glasses, thus preventing them from fogging up.
The lenses are not chemically treated so it should be remembered that when the mask is new, as is recommended for all masks, it is best to clean the lenses well with toothpaste, dishwashing liquid or simply use a lighter to burn off all the volatiles and impurities deposited on the glass. And it is also always useful before each dive to use saliva as a surfactant.
