The VIO?s large thermal lens offers the best field of view and can be removed and replaced in seconds thanks to the integrated Hinge Lock?. VIO optics are designed to maximize clarity and perception without fogging thanks to the thermal pane lens and anti-fog coatings. With Virtue?s heavy duty impact resistant lens technology, your eyes will not only be safe from paintballs and UV rays, but the field will look better than ever.
