An amazing improvement in the diving mask field of vision. World's first Direct Sashing System. [PAT. P.]TUSA has devoted years of research to improving the diving mask's field of vision. The result is the new Direct Sashing System (D.S.S.) [PAT. P.], a totally new structure. It eliminates the inner frame that blocks the field of vision and attaches the lens directly to the frame to realize a startlingly new super-slim frame. The result is a major increase in the upper/lower-left/right visibility range. It also achieves a major narrowing of the center joints connecting the left and right lenses to eliminate the vision field split. This 2-window mask, with its superior resistance to water leakage and shock, lets you view with greater freedom and clarity to further enhance your diving pleasure.
