"Quite simply the best pair of glasses that Oakley do (IMHO). Contoured around your eyes and cheek bones, yet they resist misting in all but the most extreme conditions, almost unbreakable the arms and lenses detach and a wise variety of lenses are available. The standard black iridium lenses provide fantastic contrast in medium to bright light with vivid colour transmission and fantastic optical depth. The strength and protection offered by the lens is fantastic, as a mountain biker the number of small rocks bits of tree etc that have bounced of my last pair can not be underestimated (before you ask my two year old son lost my last pair they didn't break!)."
