I recently bought these sunglasses because I am relatively new to the outside and long-distance running world and needed something aside from my everyday glasses and bought these and they work great!  I bought them for my first half marathon, and I couldn't be happier. They are light weight and provide great coverage.  Unfortunately, they look much better on my husband than on me, but I'm not concerned because they get the job done.  And for being a person who loses sunglasses frequently, the price is well worth the purchase.  They are what I consider to be a nice pair of introductory sport sunglasses.
