Terrific, well designed, and contemporary sun-glasses, issued to some of the grunts in the Alps. Have nylon frames with three sets of lenses. All are UV400, with three graduating shades: cat. 0, cat. 1, and cat. 3. The bales have unique non-slip inserts, for behind the ears. Even when you’re sweating they’ll stay put. Just in case, they threw in a “granny cord,” so you can hang ‘em around your neck. Come with fabric, drawstring baggie, to keep the set all tidy.
