Cressi Atom Mask

The Cressi Atom mask is a radical design with exceptionally low internal volume, built specifically for freediving rather than adapted from a scuba mask.

What makes the Cressi Atom mask different

It is a frameless mask. Construction material has been cut to the minimum, which is where the low volume comes from.

Inside the silicone skirt, a stiff core is co-stamped with the two lenses. That core gives the mask exactly the rigidity it needs.

Because the core replaces the usual external plastic frame, the internal volume drops well below a conventional mask.

Why low volume matters

Air inside a mask compresses as you descend, and you equalise it from the single breath you took at the surface.

Less air inside means less of that breath spent on the mask and more available for the dive.

On a deep breath-hold the difference is measurable, which is why serious freedivers care about it.

Lenses and fit

The lenses are tempered glass, bonded directly to the silicone. Tempered glass does not distort under pressure the way plastic does.

Hold the mask to your face with no strap and breathe in gently through your nose. If it holds on suction alone, the skirt suits your face.

The nose pocket is easy to pinch, which matters when you are equalising repeatedly on a line.

Care

Scrub the inside of the glass with toothpaste before first use to remove the manufacturing film, or it will fog whatever you put on it.

Rinse in fresh water after every session and store it out of direct sun with the skirt uncompressed.
