That white bump over there is probably snow. That greenish smear might be a tree. That brown thing is either a moose or a rock. If you're tired of playing this game when you ski without your glasses, Smith's Knowledge OTG Goggle could quite literally be a life saver. It's designed with extra internal space to accommodate your frames, a floating foam membrane and DriWix face foam to form a tight, fog-fighting seal around your face, and an articulating outrigger positioning system that adjusts to your face shape to eliminate pressure points without the need for manual adjustment. When you do have to do some fiddling, the QuickFit strap adjustment makes it easy, and the rear clip buckle makes getting the Knowledge strapped around your helmet a quick and easy proposition. When you're trying to pick out your line, the distortion-free cylindrical carbonic-x lenses will give you a crystal-clear view of the terrain ahead, so you don't have to guess based on color and shape. Smith hooked the Knowledge up with a Regulator adjustable ventilation system, too, so you can vary the amount of air that's flowing through if you need to de-fog.
