Don't let the low-profile design fool you—the Oakley Line Miner L Su Yiming Sig Goggles deliver an expansive, distortion-free view through a cylindrical lens with a flatter top that seamlessly lines up with your helmet for a clean, uninterrupted sight line from peak to park. The flexible O Matter® chassis conforms to your face even in extreme cold, while discreet frame notches at the temples ensure a comfortable fit over most prescription glasses. A wide, 40mm silicone-lined strap locks in place, and triple-layer moisture-wicking face foam provides day-long comfort, so you can focus on the mountain, not your gear. Every Plutonite® lens offers 100% UV protection up to 400nm, meets ANSI Z87.1, EN 174, and ISO 18527-1 impact standards, and features F3 Anti-Fog coating to keep vision clear—with an optional Iridium® coating for enhanced glare reduction and light management in any condition.
