These are by far the best pair of Oakley's I have purchased. They fit perfect on my face, much better then the gascans that I previously owned. They are lighter and even wrap around my face better, so perfect for those outdoor activities keeps dust out. I checked them out in the store before I bought them on amazon..compared them to the Fuel Cells and the Crank Case turned out to be far better. All the oakley lenses are Top Notch and real clear, almost like you're not even wearing any glasses.
