Mares X-Vision Mask, a brand new design and innovative technical solutions. Mares X-vision offers a field of vision never before thought possible in a dive or snorkel mask, with no restrictions. The optimally angled windows are designed to mesh perfectly with the central position of the eyes to provide the widest possible viewing angle in every direction. The ergonomic quick adjusting buckles, positioned directly on the skirt, make for increased comfort and hydrodynamics during a dive. In addition, this technical solution makes it easier to store the mask inside a pocket of the BC. Low internal volume and very light.
