I have had another brand I have worn for 7 years, but the quality took a drastic dive as of lately. I had switched to Gargoyles after doing some research on brands. I needed sunglasses that were rugged yet stylish. The specs on these sunglasses are amazing! They truly are top of the line. When you need something more than just a fashion accessory pick Gargoyles! I can also say I never have bought sunglasses that fit so perfectly! It's as if they were made for my face. The fact that the brand was used in Dirty Harry (Sudden Impact to be exact) and Terminator also makes it cool. They also double as safety glasses with their Shatter-Resistant Ballistic Defense System. The lenses exceed industrial standards and are capable of stopping a .22 bullet at 20 Ft. (please don't try this at home).  The lenses are also anti-fog and scratch resistant (using NASA technology). They are superb glasses and I would recomend them to anyone! 10/10
