TECHNICAL INFORMATIONS
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) before use.
To optimise the effectiveness of the anti-fog system, do not touch the lenses with your fingers or with anything greasy. Such as suncream, for example.
If the lens fogs up, rinse with clean water and rub the inside of the lens lightly with your fingers.
You can also clean your mask with soap and water, then rinse it.
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” properly, and stays stuck to your face, it’s perfect and means that it is your size and will be watertight.
If it unsticks and falls off, that means that air is getting through, and so water will get in, so you’ll need to try another size or 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.
