Design details
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.
ADAPTED FIELD OF VISION
There is a risk of losing (syncope) during a freediving session. This risk is even greater in the last 10 metres before reaching the surface.
It increases further still if the freediver raises their head to look up at the surface.
To reduce the risk of such a blackout, our design teams have developed a mask shape that increases the upward field of vision, without the diver needing to raise their head.
EQUALISATION
The mask gets pressed against the face when diving down. As you dive, pressure gets applied to the mask's flexible 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. Simply breathe out gently through your nose. Air is very valuable in underwater sports, so this equalising effect must be kept to a minimum.
SILICONE
Silicone is an extremely flexible material. A silicone skirt conforms gently to the contours of the face, creating a watertight seal.
