The Cressi Quantum Dive Mask is that as well as offering enhanced vision downwards.
The outer part of the skirt features a cooling system composed of two small heat exchangers that act as radiators. The effect is that the temperature inside the 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.
Despite the small internal membranes deviating the airflow and the external heat exchangers, the body of the Quantum mask is compact and represents the most advanced design offered on the underwater vision market.
