The SEAC Italica mask is a single lens mask with a dual thickness skirt that helps to create a better seal around your face. Ultra clear tempered optical glass lets plenty of light in with fewer impurities so you get a true image of underwater. Tear drop shape lenses improve the field of view to the side but also when looking down. The reverse teardrop shape to the lower frame combined with the raked angle skirt brings the bottom of the frame back in toward the face and moves the frame out of the field of view. This not only improves lower visibility without the need to tilt the head but also reduces the internal volume of the mask.
