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.
Gresso glasses are just amazing. I’ve been buying Oakleys for years but after trying Gresso glasses I found out how amazing the quality and the styles. In less than a month I bought my second pair. Very very recommended.
