The I/OX from Smith is an excellent goggle for any skier or snowboarder looking for a large frame and lenses that can easily be swapped out when the light shifts on you. The Spherical Carbonic-X Lens delivers an ultra-wide field of view without distorting your peripheral vision. 5X Anti-Fog Coating and the AirEvac System work together to prevent lenses from fogging up on you, even in tough conditions. A Responsive Fit Frame adapts easily to nearly any face shape, while the Dual Axis Outriggers accommodate any helmet shape for a simple to fit goggle. The I/OX features Smith's Chromapop Lens that filters light and allows you to see in high-definition with the ability to see the texture of the snow more clearly and reduced strain on your eyes. A Porex Filter is included with each lens that eliminates distortion at high altitude. Smith's Pivot Quick Release Lens Change System takes only a minute to change lenses when the clouds blow away and the sun breaks out. If you want a goggle that has been tested and used for seasons by sponsored athletes, the Smith I/OX will have you looking rad and riding rad on the mountain.
