Visio Tri-Ex Mask

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 dramatically over traditional masks. 

The M-31 mask gently conforms to the contours of your face. Constructed with crystal silicone, this mask has been crafted for divers who want a wide front lens combined with a low volume design. Like all TUSA masks, it incorporates a wide range of features to enhance comfort and provide clarity of vision. 

TUSA's Patented 3-D Wide Split Strap is a true Three-Dimensional Design that Snugly Fits against the Head's Natural Curvature. The 3-D Strap offers Unprecedented Comfort and Fit unlike standard flat mask straps. The 5 Angle Strap Adjustor allows for a 5-Position Micro-Adjustment on both the left and right sides of the mask. This enables Vertical (up/down) and Horizontal (left/right) Pressure on the Face to be Delicately Adjusted for the Optimum Fit.
