I needed a new pair of glasses and could afford to spend $100+, I bought these because I had another pair in the past and they were the best sunglasses I have ever had, in fact I still have them.  These glasses are great they are extremely durable I've dropped them, sat on em, thrown them around etc.  For a long time I was looking for some square aviators and couldn't find anything. I've had Persol, Rayban, Mosley Tribes, Oakleys, Oliver Peoples, Spy, and Von ZIppers none of these brands have had the quality, value, durability like AO
