These are a new pair of sunglasses I got from Native's excellent warranty policy. They've only been taken out to be photographed and have never been worn. Comes with an extra set of sport-flex lenses (a much lighter tint for low light conditions), a hard case, and a cloth pouch.
Before I had to get them warrantied (a problem due my own stupidity) I used these in everything from hiking to multi-day biking trips. The interchangeable lenses are fantastic when you want some eye protection, but don't need such a dark tint. Only selling because I ended up with another pair of sunglasses while the warranty was being processed, so I have no need for these.
