I've worn these sunglasses all over the world (pictured: Greece, Morocco and Kenya). They fit great, provide awesome sun protection and -- the best part -- they fold up and fit into a case, so you can actually carry them in a front pants pocket.
I tend to break everything, but these sunglasses seem to be indestructible. I love mine. I think you'll love them, too.
