    Design details

    Anti-fog film

    Hydrophilic film laminated directly onto the glass. This film prevents the lens from fogging up during use.

    Maintaining the effectiveness of the anti-fog system

    This mask needs no preparation (toothpaste, flame, anti-fog spray). To optimise the effectiveness of the anti-fog system, do not touch the lenses with your fingers or with anything greasy. Over time, and with the use of greasy substances on the skin (sun cream, make-up, etc.), the anti-fogging functions of your lens can become less effective. To restore the hydrophilic properties of your mask, simply clean it gently with a mild soap (Marseille soap).

    Tempered glass lenses

    Tempered glass is two to five times more durable than traditional glass. If it shatters, it breaks into small pieces, reducing the risk of a major accident.
    It has the advantage of better scratch resistance compared to a polycarbonate lens.

    How to choose the right mask size?

    You need to position your mask on your face without the strap, and press with your hands to make sure it’s firmly in place, blocking your breath.
    If the mask “suctions” well and sticks to your face—perfect! It’s your size and will be watertight in the water.
    If, on the other hand, it slips and falls off, it’s because air is getting through and water will seep in, so you need to try another size or choose another mask.

    Internal volume

    The volume of air inside the mask, between the face and the lens, represents the internal volume.
    For freedivers and spearfishers, the internal volume of the mask should be as low as possible to make it easier to equalise.

    Equalising the mask

    The mask gets pressed against the face when diving down. As soon as you go under, the volume of air trapped in the mask decreases. So the skirt presses against your face like a suction cup.
    To avoid this phenomenon, which is painful for the eyes and can lead to barotrauma, it is important to equalise the internal pressure of the mask by blowing out gently through the nose.
    Air is very valuable in under water sports, so this equalising effect must be kept to a minimum.
