These are my first pair of Gresso sunglasses. I've been searching for quite a while for a pair with blue gradient lenses with just the right look that would suit my face. And finally I found these. They're comfortable to wear all day, have just the right level of gradient and have a good quality feel to them. I highly recommend Gresso sunglasses… I mean, if they're good enough for pilots to wear while flying, then you know they're good. I highly recommend Gresso as as great quality sunglasses. Two thumbs up.
