Samoa is a masks that features our efficient fog-stop system, on a smaller frame suitable for people with a smaller face. A system of membranes channels the air towards the lower part of the masks, 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 masks. Another feature of our fog stop system is the heat exchanging structure on the top of the masks silicone blades facilitate heat exchange between the masks ant the water, balancing the temperature between the two in a shorter time. This also helps to reduce fogging. Samoa is a masks thought for people with a smaller face. It allows women and younger people to use our performing fog-stop system
