The wife got me some serious shades for Christmas since my last pair eventually broke in half. I had repaird them many times (the best involving JB Weld and a sliver from a Kroger key chain card). The were finally beyond repair and I was using a pair we found in the back seat of her car that looked like alien eyes or something.
Check the new ones out.
Natives - Ripp - Pale Ale Fade
These things come with a lifetime warrenty. Of course you have to send them $20 to get a replacement pair, but that would have been better than paying full price for a new pair like we had to do this time.
