The Oakley Canopy Snow Goggles frees you from the tunnel vision of ordinary goggles. Oakley has expanded the lens volume and created a low-profile frame design. That means you’ll enjoy a wide-open view with maximized peripheral and downward vision. The razor-sharp optics take advantage of Plutonite® lens material that filters out 100% of all UV, and with the combination of dual vented lens architecture and F3 anti-fog coating, you’ll have superior protection against the threat of fog ups. Oakley’s O-Flow Arch technology makes the simple act of breathing a lot easier. For even more comfort, the face foam is a triple layer with moisture-wicking fleece, and the O Matter™ chassis stays flexible in bone-chilling weather while the strap anchor plates distribute pressure evenly. The wide, adjustable strap has silicone lining to stay securely in place. Canopy is designed for improved compatibility with helmets and most prescription eyewear frames. As far as protection goes, this Oakley goggle meets the impact resistance standards of ANSI Z87.1 and EN 174:2001. The Fire Iridium (16% VLT) Lens is a contrast lens with a protection index of 3 for medium to bright light. Improves visual acuity. Features an Iridium® coating to further tune contrast and reduce glare.
