2-lens diving mask with the patented technology Stop-Fog system which reduces drastically to have fog over the lenses without the need of any anti-fog solution. The moist air is channeled by a system of membranes in the mold around the eyes and nose, which deflect the flow toward the rubber walls and not toward the glass. The mask has two external heat exchangers that function as a cooling system, reducing the temperature inside and preventing the glasses from fogging up by trapping moisture droplets. It is compact and smaller in size than a classic diving mask without reducing the field of view thanks to the new internal ribs making adaptable to any face. The Naxos is designed and manufactured in Italy by Cressi, an Italian brand pioneer in freediving, spearfishing, and scuba diving equipment since 1946.
