The one and only 6-lens mask in the world. The Esa revolutionizes the mask concept.

For the very first time, divers can enjoy peripheral vision with Mares’ revolutionary six-lens mask.
The Esa mask features a wide panoramic window with an extended range of vision compared with traditional masks. With the Esa, divers can get what they have been deprived of for such a long time: they just have to lower their eyes to be able to see their weight belt, the upper B/C straps and to read any wrist-worn or console-mounted instruments without having to raise them. The Esa is the ideal mask for divers with vision problems. Optical lenses can be fitted in the bottom windows to read the dive computer or watch, whereas the large lenses can be corrected for short-sightedness only. The Esa is extremely comfortable, easy to equalize, and its strap is equipped with quick-adjusting swivel buckles.
