Fiji is a snorkeling mask that features the ultimate cressi fog stop system. A system of membranes channels the air towards the lower part of the mask, away from the glasses. A second membrane seals the eye socket, so that warm air coming from exhalation does not get on contact with the glass at all. This dramatically limits the fogging of the mask. Another feature of our fog stop system is the heat exchanging structure on the top of the mask silicone blades facilitate heat exchange between the mask ant the water, balancing the temperature between the two in a shorter time. This also helps to reduce fogging. Fiji is a mask thought for snorkeling. It features an elastic band, making it an easy to use mask, that will be appreciated by beginners, people with long hair. It can be used for scuba diving too, but keep in mind that an elastic strap is not as firm as a silicon one
