Skirt

Flexible part of mask in contact with face.

Silicone

Silicone is an extremely flexible material. A silicone skirt conforms gently to the contours of the face, creating a watertight seal. The material is hypoallergenic.

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 underwater sports, so this equalising effect must be kept to a minimum.
