Familiarity: I've put it through the wringer
I ordered these glasses for a 30 day mountaineering expedition in British Columbia. I left the case at home and shoved the glasses in a sock to save weight during the bushwacking portion of my trip. High quality glasses that held up throughout my trip. Be careful with the magnetic side guards. I almost lost them a few times during the schwack on the way out!
