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:- Available in Prizm™ Lens Technology options- 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 upon ANSI Z87.1, EN 174, and ISO 18527-1
