The great novelty of the Quantum mask is that in addition to offering increased downward vision, it prevents the phenomenon of fogging, through a thermoregulation inside the mask of the hot and humid air that comes out of the nose. This is channeled by a system of membranes obtained in the mold around the eyes and nose, which divert the flow towards the rubber walls and not towards the glass.

On the outside of the walls there is a cooling system consisting of two small heat exchangers that work like real radiators. The effect is that the temperature inside the mask drops, approaching the outside temperature, and that the humidity droplets are trapped before the air reaches the glass, thus preventing them from fogging up. Despite the presence of the small internal membranes that divert the air flow and the external heat exchangers, the structure of the quantum mask is still compact and represents the most advanced that the market has to offer in underwater vision.

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, dish soap or simply use the lighter to burn all the volatiles and impurities deposited on the glass. It is also always useful to use saliva as a surfactant before each dive.

Characteristics:

• Internal membranes: a patented membrane that surrounds the internal cavity of the nose and both internal cavities of the eyes that acts as a barrier, retaining moisture that involuntarily escapes from the nose of the diver during mouth breathing. The result is that not only is moisture channeled away from the lenses, thus preventing them from fogging, but it also reduces the need to equalize the pressure. To further improve the anti-fog effect, Cressi suggests, the first few times you use the mask, to spray anti-fog solution or apply a little saliva to the inside of the lenses and then rinse them with water.
• Heat Exchanger: The outside of the facepiece features a cooling system consisting of two small heat exchangers that act as radiators. Thanks to this system, the temperature inside the mask is lowered (approaching the outside temperature) and moisture droplets are trapped before the air reaches the lenses, preventing them from fogging up.
