Tusa M-31 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.

Features:

168° panoramic view through 1 window lens
Patented domed side windows
Reduced frame structure to reduce blind spots
Patented round edge skirt for increased comfort and better seal
Three-dimensional strap for unprecedented fit
Five-position strap angle adjustor for micro-adjustment
Colors: Aquamarine, Black, Cobalt Blue, Flash Yellow, Shark Silver, Translucent
Also available in black silicone (M-31QB): Black, Black/Red
