Oakley has expanded the size offering of the Line Miner to include the Line Miner XM. This medium version of the Line Miner offers all of the great features the Line Miner is known for in a smaller fit. An expansive lens will give you the ultimate peripheral view out on the slopes so you can always see what is going on around you. PRIZM Lens Technology enhances contrast and makes safety and enjoyment your top priority. With PRIZM Snow lenses, reading the edges and finding your line has never been more fun or easier to do. The low-profile design increases helmet compatibility by reducing gaps where air can get in. And if you need them in prescription we can do that too!
