The Oakley fives are a very simply designed pair of sunglasses. They are very lightweight making them very comfortable and easy to forget your wearing them. The design is all plastic. They come in a few different colors I own the black ones, which are very nice, they have drak lenses and they look great with anything you are wearing. They have "plutonite" lenses, which protect your eyes. These lenses are tinted quite heavily and are very effective in the sun. Oakley did a great job with these sunglasses, making them simple and very affordable. I have owned them for 3 years now and with some care they have lasted very well, they still have no scratches on them, and have been sat on and such, they are quite durable and should last anyone a long time. I love this product and would highly recommed any oakley's product to anyone.
