These specs have all the versatility of the m-frames without the total jock-geek look (speaking as an m-frame'r). The clarity of the polarized lenses is unbelievable, as others have said. They're also comfortable. The half-jacket case, with room for additional lenses is a worth while purchase for protecting these puppies. If you really like using these, getting some extra lenses for low light (HI Persimon) or cloudy conditions (g30) is useful - especially if you're cycling and wear contacts, for instance. One recommendation: try on the XLJ and the regular lens shapes first to see which suits you better - smaller faces seem to do better with the regular lenses.
