Oakley is releasing a more compact version of the Line Miner that was released last fall. The XM is ideal for those with smaller faces or who simply prefer a closer fit. Like its wider sibling, the XM features a flexible frame that helps conform to your face shape as well as dual vents on top to help dump hot air and prevent fogging. Its Prizm lens enriches contrast for a boost in visibility, which will surely result in an orgasm for your eyeballs when gazing around the mountains this winter.
