The first time we spotted these Oakley Oil Drum Sunglasses was on the face of a driver in the Formula 1 paddock before a race. If you want glamour and sophistication with rock star attitude, Oakley's Oil Drum delivers on a scale that's larger than the oversize lenses--without the frame weight normally associated with cheap, big-frame sunglasses that use heavier acetate frames. Oakley used their O Matter material around the lenses and down the ear stems so these sunglasses feel good throughout the day. Along the corners you'll find precision hinges with a dual-cam design that's distinctively different from conventional eyewear hinges. The Oakley Oil Drum offers the same Plutonite lenses with Oakley's High Definition Optics (HDO) found in Oakley's successful Gascan sunglasses, but the full 8.75 base lens curvature is larger with the same distortion-free optical excellence. Like the Gascan, the Oil Drum is a great fit on medium to large faces.
