We laser cut the whole frame from a single piece of metal. Our frames don't have welded joints, which always are the critical points in every pair of traditional glasses. You can bend or twist them but they always return to their original shape.
First I'm just going to say this,.. I love the Chicago, even though I returned because of the size, I love how they are made, pure quality. I'm gonna have a gresso sunglass in my collection, PORTLAND WAIT FOR ME BABY!
