Cressi Naxos Mask - Diving Mask with Anti-Fog System, Black/Black, One Size, Unisex Adult

Cressi is a family-owned company that has been passionately developing aquatic sports products since 1946 The main innovation of the Quantum mask is that it prevents the fogging phenomenon through internal thermoregulation of the warm and humid air that comes out of the nose This air is channeled by a system of thin membranes placed in the molding around the eyes and nose that divert the flow, preventing hot exhaled air from directly accessing the crystals The external part of the skirt has a heat exchange system made up of two small heat exchangers that act as radiators The effect is that the inside temperature of the mask drops, approaching the outside temperature and the microdroplets of moisture adhere before the air reaches the lenses, preventing them from fogging up
