I use them for cycling, hiking and many other outdoor activities. They are cheap, durable and good looking. They last a long time and I would prefer black/smoky lenses to blue just because it shows blue sweat stains! I heard about it from an online outdoor writer - PMAGS. He discusses what works, not just fashion stuff.
