I purchased a pair of Roka Halsey sunglasses (black on black) about four months ago and have worn them on most of my runs and several rides. I also wear them as regular sunnies because they do not make me look like super sport dork (full disclosure: I am a handsome bastard so that is probably not possible). I live in the subtropics and sweat heavily (I could sweat inside an igloo). Typically, I run 35-50 miles per week and the glasses have held up phenomenally well. When I'm done running, I rinse them off and they are good to go. I've worn them out in the ocean on small surf days when I take the log out as well. For rides, I've had no issues as well. The glasses are not aero by any stretch of the imagination, but that should be obvious. I do not take very good care of my glasses and they still look brand new. Two thumbs up. Carry on.
