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.), 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 and left/right visibility ranges. It also achieves a major narrowing of the center joints connecting the left and right lenses to eliminate the vision field split.

• A direct sashing 2-window design for super-thin form
• The narrowest center joints eliminate the vision field split
• Eight color choices

M-20QB
In black silicone and with a super-thin form for underwater photographers, this design features a black silicone skirt and strap. The frame is available in Black/Red (BK/R).

High-Tech Age design for the ultimate function
The M-20 minimizes frame volume to achieve a bold slim design and lighter weight. TUSA has made painstaking analyses of the features of the human face (including skin and facial bones) to lighten the load and any abnormal feeling when attaching the mask to the face. The M-20 offers a superior fit and aesthetic beauty.
