Not everyone fits the massive goggles of today, so Oakley came around with the M (medium or mid-sized) Line Miner Goggle for the smaller faces out there. The original Line Miner has one of the largest peripheral views on the market, and the Oakley Line Miner M Goggles are no exception to this top-of-the-line construction. Combine that with revolutionary Prizm lenses for definition and clarity across a wide range of light conditions and you get one of the sweetest, best performing goggles on the market today.
