The Visio Tri-Ex boasts an ultra-wide viewing angle of 168 degrees. Designed and developed by the top engineers at Tabata Japan, the Visio Tri-Ex uses water refraction as an aid to increase the field of vision using 2 domed side-mounted lenses.

That's 61 degrees wider than the old model (Pano Geo)! And there's more! The Visio Tri-Ex frame is lighter and locks into place a high-quality crystal silicone skirt with extra wall strength, a wide face dimension and the same edge design found on the Serene masks released earlier this year.

One unforeseen benefit is that this mask can help keep you in better contact with your buddy. The side-mounted domed windows offers an amazing Panoramic-view ensuring you don't miss any special moment.

The Visio Tri-Ex also features some personal adjustments helping this mask suit any face. The side strap can be easily adjusted with one pull and the side buckles are fitted with the TUSA 5-point positioning system, which lock the angle of the frame in place.

Need prescriptive lenses?

Features
TUSA 3D Mask Strap

3-D Strap

TUSA's patented 3-D 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.

TUSA Panoramic View

Panoramic View

Panoramic View masks feature a variety of designs offering an incredibly wide field-of-view. Several designs incorporate minimum frame volumes, domed side-windows, reduced frame structures as well as three and four window styles for maximum vision.

TUSA Round Edge Skirt

Round Edge Skirt

TUSA's Round Edge Skirt features a proprietary round edge cross-sectionally shaped skirt. This rounded edge results in a soft fit that suppresses pressure and reduces creasing left on the face. The "planar fit, instead of linear fit" silicone skirt maintains great fit and unprecedented comfort.

TUSA Angle Strap Adjuster

Angle Strap Adjustor

The 5 Angle Strap Adjustor allows for a five 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.
