I love the fit and look of these sunglasses. They are super light and very comfortable to wear. I am one of those people that gets headaches if glasses pinch the nose or behind the ears too much. They stay on without budging, but are still so comfy. wore them backpacking and they worked great. Super clear optics and scratchproof. My only thing I have noticed is that the smudge coating seems to only be on the exterior of the lens, the inside gets smudged easily. But only a minor gripe. Otherwise, they are awesome shades.
