The original Line Miner goggle was created with the purpose of providing the ultimate in peripheral vision, with a cylindrical style design. We expanded the size offering as a complete family, adding this medium-sized goggle to the arsenal, equipped with Oakley’s industry-leading Prizm Lens Technology. This low-profile frame design provides increased visibility and improved helmet compatibility, and features an expanded lens volume for optimized peripheral vision and a 40mm wide adjustable strap. Integrated frame strap anchor slots ensure a secure fit over helmets, and discreet frame notches under strap anchors provide compatibility with most RX frames.Specifications:- Fit: standard Take care of your lenses:- To help maintain the High Definition Optics® (HDO®) of Oakley lenses, your new eyewear comes with a specially-woven electrostatic Microclear™ bag for cleaning and storage.
