Cressi Sub Cressi Naxos Diving Mask ADS 535050

The Naxos mask is compact and smaller in size than a classic diving 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 escaping from 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 thoroughly with toothpaste, dishwashing detergent or simply use a lighter to burn off all volatiles and impurities deposited on the glass. And it is also always useful before each dive to use saliva as a surfactant.Features:- Patented anti-fog system- Tempered glass- Double injection technology- Flexible buckle n with micrometric adjustment- Inclined lenses- Bi-silicone strap- Double injection silicone strapInner membranes:- A patented membrane surrounding the inner nose pocket (1) and both the inner eyes pockets (2) which acts as a barrier and traps any moisture escaping from the diver's nose involuntarily when breathing through the mouth. The result is that not only is the moisture channeled away from the lenses, thus avoiding the fogging up of them, but it also reduces the need to compensate for pressure. To further improve the anti-fog effect, Cressi suggests, the first times that the dive mask is used, to spray some anti-fog solution or to apply some saliva on the inside of the lenses and then to rinse them with water.Heat exchanger:- The external part of the skirt features a cooling system composed of two small heat exchangers that act as radiators (3). Thanks to this system, the temperature inside mask drops, coming closer to the external temperature and the droplets of humidity are trapped before the air reaches the lenses, preventing them from fogging up.
