A buddy of mine bought a pair of these glasses at an LPGA tour event and raved about the quality and price. When I found them online I put my order in. They arrived a week ago and I am very satisfied. I am a runner and am always looking for glasses that won't fog up when I sweat, and will not bounce around as I am running. I have taken these on three long runs so far and have not had any of the issues I have experienced with expensive name brand sunglasses. Would definitely recommend these.
