Picked these up this past May to be my everyday around-town pair of glasses. They're super light-weight and stay put on my face pretty darn well for a non wrap-around style frame. The styling is spot on, the frames aren't obscenely large but are bigger than a traditional Rayban, a perfect middle ground in my opinion. Construction is just nylon grilamid so they don't have the acetate feel that a lot of people love. Doesn't bother me personally but they aren't going to be an especially tough frame. That being said, I haven't been gentle on these glasses and the are holding up just fine. The lenses seem to be a bit prone to collecting dirt and fingerprints, so be prepared to have a cleaning cloth handy if you like your lenses to be spick and span. My only concern with this frame is the removable temples, I'm just not sure how many times the hinge and temple pieces are going to be able to handle he removal process. You just have to be very deliberate and careful while switching the temples. Solid overall piece, would recommend to anybody looking for some casual and stylish eye-wear.
