A mask is one of the most important pieces of dive gear and we think the ES155 frameless mask is it. With exceptional visibility and superior comfort being in the forefront of the design, diving on a reef or exploring a cave or wreck couldn't be more exhilarating. The wide angle of vision provided by the single lens and by not having the frame of the mask over the nose substantially increases overall underwater visibility. Seeing clearly underwater over the entire field-of-view is possible with the ES155's ultra clear glass in its lens design. The glass is also tempered for safety if it should ever break.
