Oakley Sutro TI Sunglasses are a stylish and functional accessory that will keep you looking and feeling great all day long. With a bold and modern design, these sunglasses are sure to turn heads wherever you go. The frames are made from lightweight and durable O-Matter material, which provides a comfortable and secure fit for extended wear. These sunglasses also feature Oakley's patented Three-Point Fit, which ensures that the frames only touch your head at the bridge of your nose and behind your ears. This reduces pressure points and ensures a comfortable fit for all-day wear. Unobtainium earsocks and nosepads ensure a secure and comfortable fit even during sweaty activities.
