These are some awesome glasses. They exude cool. They are expertly crafted. But the fit for my head leaves a little to be desired. Because of the thin arms, and folding hinges, they don't grip your head particularly stiff or tightly. I don't have this problem with other resin or metal glasses. I think its unique to this design. Also because of the nose hinge or shape, it tend to slide down there a little bit too. This doesnt happen on either my sport RB's or wayfarers. So these are great if you're really active. (at least with my more narrow shaped head. But for all those complaints--these are just plain cool. And you don't see everyone else wearing these like you do with the wayfarers and other aviators in LA. And they fold up which is pretty sweet. The lenses are of excellent quality and are much clearer than my other polarized lenses.
