Great concept, so close to perfection.... The ROAV shades are exceptionally well built. They also defy expectation, as you pull them out of the pouch your brain can't compute how light they really are-- Superlight. The metal is excellent quality and although razor-thin, still, somehow, feels strong and sturdy. The one drawback these shades have is a pretty nasty glare issue INSIDE the lens. Let me clarify, this isn't glare coming from outside into the lens, the lenses are excellent at cutting that glare, this is a reflection of light on the inside of the lens, specifically when you are in a car or somewhere in close proximity to bright reflective things in your immediate periphery. This is a minor issue and not a dealbreaker whatsoever. The glasses and lenses are wonderful, but the close proximity peripheral reflection issue means they aren't suitable for driving. Great shades to have in your pocket to go to the movies, play on the beach etc. But if you are going to be behind the wheel, use a different set of shades. OVERALL: really good glasses, lightweight, travel perfectly, great for most non-driving activities.
