The Mares Sealhouette is a low-volume, twin-lens mask built for spearfishing and freediving, where the air you spend to equalise the mask comes out of a single breath. Its low internal volume means less effort on the way down and easier clearing.

The skirt and strap are made from silicone, and the distance between the lenses and your eyes is kept short. That close fit, together with the dual-lens layout, gives you a wide field of view so you can spot fish and track movement around you.

The buckles sit low and mount directly on the skirt rather than on a bulky frame, which keeps the profile slim and lightweight. It is a mask for breath-hold divers who want low drag and comfort on long sessions in the water.
