In skiing and snowboarding, taking the Fall Line refers to the line down a mountain that is most directly downhill. Inspired by Line Miner and fusing the large field of view from a rimless goggle, Fall Line M is the latest addition to Oakley’s LINE SERIES of cylindrical style snow goggles. With a mid-sized fit, Fall Line M is optimized for a wide variety of faces and is engineered to fit perfectly with most helmets. Designed with Oakley’s Ridgelock Technology, changing lenses is quick and easy while still allowing for a complete lens seal to prevent harsh conditions from penetrating into your goggle.Features:- Fit: Medium- Microbag Included For Storage And Lens Cleaning- Ridgelock Lens Change System- Discreet Frame Notches At Temples Provide Compatibility With Most Prescription Eyewear- Wide 40mm Wide Adjustable Strap With Silicone Lining For A More Secure Fit- Flexible O Matter® Chassis Conforms To Your Face Comfortably, Even In Extreme Cold- Rimless Frame Design Provides Increased Visibility And Improved Helmet Compatibility- All-Day Comfort Of Triple-Layer Face Foam With Moisture Wicking Polar Fleece Lining- Injection-Molded Plutonite® Lens Material Provides 100% Protection Against Uva / Uvb / Uvc & Harmful Blue Light Up To 400nm- Optically Correct Dual Lens With F3 Anti-Fog Coating- Glare Reduction And Tuned Light Transmission Of Iridium® Lens Coating (Optional)- Meets Impact Requirements Based On Ansi Z87.1 And En 166 StandardsSpecifications:Prizm Snow Jade Iridium:- Light Transmission: 13%- Light Conditions: Sun & Clouds- Contrast: IncreasedTechnology:- Prizmâ„¢ Snow Lenses: Oakley’S Exclusive Lens Technology Designed To Enhance Color And Contrast So You Can See More Detail.
