Much like a large piece of metal often used as protection against an enemy's blows, the Oakley Turbine Rotor Sunglasses combine wide lens coverage with high performance that ultimately provides stylish protection from the sun's harmful rays. Constructed with the stress resistant O-Matter frame, the Turbine Rotor features the Three-Point-Fit system that eliminates pressure points while the Unobtainium earsocks and nose pads encourage ample grip even when conditions turn from sunny to surly and soggy. And last but not least, the Plutonite lenses offer 100% UVA, UVB, and UVC protection.
