• It features the Cressi's Advanced Stop Fog system that traps the moisture escaping from the nose reducing drastically the fogging up.
• Moist air exiting the nose is conveyed by a system of membranes embedded in the molding around the eyes and nose and diverting the flow towards the rubber skirt rather than the lenses.
• The world's first mask with heat exchangers acting as radiators. The temperature inside the goggle drops as it approaches the outside temperature, and droplets of moisture are trapped before the air reaches the lenses, preventing them from fogging up.
• Features inclined and inverted tear-drop lenses for improving downward visibility, a Cressi patented design (US 6272693).
• The buckles are integrated with the frame with a swivel system that are easy-to-use for quick strap length adjustment. This technology is patented by Cressi (US 8281417 B2).

The major innovation with the Quantum mask is that as well as offering
enhanced downwards vision, it avoids the fogging phenomenon through the
internal thermoregulation of the warm, damp air exiting the nose. This air is
channeled by a system of membranes set in the molding around the eyes and nose
and deviating the flow towards the rubber skirt rather than the lenses. The
external 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 presence of the small internal membranes
deviating the airflow and the external heat exchangers, the body of the
Quantum mask is nonetheless compact and represents the most advanced design
offered on the underwater vision market. The lenses are not treated chemically
and it should be remembered that when the mask is new, as is the case with all
masks, we advise you to clean the lenses carefully with toothpaste or
dishwashing detergent, or simply use a lighter to burn away all volatile
materials and dust that may have collected on the glass. It is also always
useful to use saliva as a surfactant before every dive.
