Cressi Quantum Diving Mask

It features the Advanced Stop Fog system that traps moisture from the nose, which significantly reduces fogging. Moist air from the nose is transported by a system of membranes embedded in the shape around the eyes and nose that direct the flow to the rubber edge rather than to the lenses. The world's first heat exchanger mask that acts as a radiator. The temperature inside the glasses decreases as it approaches the outside temperature and moisture droplets are trapped before air reaches the lenses to prevent fogging. Features angled and inverted teardrop lenses to improve vision, a patented Cressi design (US 6272693). The buckles are integrated into the frame with an easy to use rotation system for quick adjustment of the strap length. This technology is patented by Cressi (US 8281417 B2).
