TECHNICAL INFORMATIONS
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.
Skirt
Black hypo-allergenic silicone skirt for comfort and seal.
Micro-adjustment buckles
Micrometric buckles together with the notched strap on either side of the mask allow easy and highly accurate adjustment of the mask, even when wearing gloves.
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 must be minimised to facilitate equalisation.
Equalisation
The mask is pressed against the face when descending. As you dive underwater, pressure is applied to the mask’s soft skirt, reducing the internal volume and pressing the mask against the face. This phenomenon, which can cause pain in the eyes, can be avoided by equalising the internal pressure of the mask and the external pressure exerted by the water. Simple breathe out gently through your nose.
Air is very valuable in under water sports, so this equalising effect must be kept to a minimum.
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.
