I really love these sun glasses so far. I've been using the Cutline glasses for about a year, and while the Cutlines are stacked with cool features, I must admit that the simplicity of the Spinshield Air is refreshing. The coverage is amazing - no watery eyes in the winter! They are super light! And they look really awesome - I've had 3 complements on them during my first 2 group rides! I went with black/black so that these go with EVERYTHING. Really a great product for both cycling and running!
