The M-31 Visio Tri-Ex mask is a revolutionary new 3-window design offering an ultra-wide 168° panoramic view.  This amazingly wide viewing angle is achieved by the incorporation of domed side windows and the significant reduction of frame structure around the lenses, increasing the field of vision by 1.6x over traditional masks.

Additionally, the Visio Tri-Ex is equipped with TUSA’s patented Five Position Strap Adjuster, Round-Edge Skirt and 3-D strap for superior fit and comfort.
The M-31 Visio Tri-Ex is offered in 6 colors: Cobalt Blue, Aqua-Marine, Black, Shark Silver, Translucent and Flash Yellow as well as 2 Black Silicone colors: Shark Silver and Black/Red.
