CRESSI FIJI MASK
• Inner membranes
A patented membrane surrounding the inner nose pocket and both the inner eyes pockets 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. 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.
