Unique design with a unique technology. This lightweight foldable mask offers both outstanding fit and comfort along with a broad field of vision for one incredible mask. The Essence scuba mask is the maximum expression of LiquidSkin technology. Silicone and glass come together to create a mask that is truly one of a kind. This patented, Bi-Silicone technology uses two different types of silicone: a firmer portion for support structure and a softer portion for contact with your face. This creates a mask that is 45% softer for unparalleled comfort and 270% more elastic for a perfect fit. Buckles on its skirt allow it to fold up for easy storage.Features:Quick-adjusting buckles on the skirtLight, foldable, easy to store
