NOT hype. My Nike sunglasses are crystal clear. They were 100 retail, but I had some cashback from discover card for $80, and they were on sale, and a bunch of other stuff, ended up paying $15.17 for the glasses and a $65 retail watch!
They dont distort my vision, and are very clear. They also fit my face very nice, and I barely notice they are on my face at all. I have a cheap pair that look a Chinese copy (the nike's are made in Italy) and the cheap ones are very stiff on my head, dont stay on as well during exercise, remind me im wearing sunglasses, BUT they protect my eyes from bugs and road dust while biking, things I WONT submit my nike shades to...The lenses in the cheapies arnt too bad, but not what I want for driving or relaxing....
