Cressi Quantum + Itaca Ultra Dry Combo – Snorkelling Combo Set, Transparent/Black, One Size, Unisex Adult

The great novelty of the quantum mask is that in addition to offering increased downward vision, it avoids the phenomenon of fogging by thermoregulating the warm, moist air escaping from the nose inside the mask. This is channelled by a system of membranes in the mould around the eyes and nose, which divert the flow towards the rubber walls and not towards the glass. On the outside of the walls is a cooling system consisting of two small heat exchangers that function like radiators. The effect is that the temperature inside the mask is lowered, bringing it closer to the outside temperature, and that moisture droplets are trapped before the air reaches the glasses, thus preventing them from fogging up. Despite the presence of small internal airflow deflection membranes and external heat exchangers, the quantum mask’s structure is nevertheless compact and represents the most advanced the market offers in underwater vision. The lenses are not chemically treated, so it should be remembered that when the mask is new, as is recommended for all masks, it is best to clean the lenses thoroughly with toothpaste, dishwashing liquid or simply use a lighter to burn off all volatiles and impurities deposited on the glass. It is also always useful before each dive to use saliva as a surfactant The itaca ultra dry aerator has an internationally patented dry protection, which prevents the ingress of water during surface use in any position. The new mechanical device has as many as three movement joints, the counterweight of which guarantees immediate opening of the upper valve both in and out of the water. The end section is equipped with a smooth corrugation on the inside, which keeps the snorkel away from the mouth during use with the rebreather. The mouthpiece, made of soft silicone, has a particularly ergonomically designed angle, with a reduced bite size for prolonged use without sore gums. The mouthpiece body consists of two pieces, with an angle that ensures better and faster water drainage. A bottom purge valve allows immediate cleaning when needed
