The Oakley Prizm Crowbar Snow Goggles have taken goggle technology to the highest elevation of performance as the first Oakley ski goggle with struts to balance and distribute frame pressure for all-day comfort. The contact area has been engineered to match facial contouring for a precise anatomical fit. Silicone backing keeps the strap in place. Triple-layer fleece face foam maintains comfort while wicking away the sweat of all-out sessions. The lightweight and flexible O Matter® frame is combined with extended lens size is shaped with curvature that opens your peripheral and downward view, and the patented innovations of High Definition Optics® (HDO®) maintain startling clarity at every angle of vision. Even the best optics on the mountain are useless if fog buildup corrupts your view, so the lens in this performance goggle is enhanced with a permanent, specially formulated anti-fog treatment.
