Our design teams have created this mask for confirmed freedivers. It allows you to observe sub-aquatic life while breathing up to a depth of 30m.

The very soft silicone skirt is very comfortable and the small volume makes for easy equalisation when diving. Excellent hold, thanks to the wide strap and precise adjustment.

PRODUCT BENEFITS

Field of vision

Two-window mask to focus the view and avoid reflections.

Compact design

Low volume for better equalisation when diving.

User comfort

Very soft silicone, with a large contact zone. Micrometric buckle.

TECHNICAL INFORMATION

Micrometric adjustable buckle

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 free-divers and spear fishermen, the internal volume of the mask must be as small as possible to facilitate equalisation.

Equalisation

The mask is pressed against the face when diving. As you dive underwater, pressure is applied to the mask's soft skirt, reducing the internal volume and pressing the mask against the face. To avoid this painful phenomenon on your eyes, it is important to equalise the internal pressure of the mask and the external pressure from the water. To do this, simply breathe out gently through your nose. Air is precious in these sports, so the equalisation action should be minimal.

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.
