Oakley's SI Tightrope sunglasses blend style, comfort and practicality to produce functional, ultra-lightweight eyewear that can be worn in any lighting situation. The ergonomic, hi-modulus C-5 frame is built to sit securely on the ears via a three-point fit, that also keeps the lenses in perfect optical alignment. The stems feature patented hydrophilic Unobtainium earsocks to ensure comfort and security. They are also thin enough for use with a helmet. The Plutonite lenses are designed with XYZ Optics to maximize clarity and protect eyes from harmful UVA, UVB, UVC and blue light up to 400 nanometers. These glasses may sport a sleek, low-key look, but they are engineered for comfort, sun protection and functionality.
