The Oakley Crankshaft sunglasses are a fusion of the ever popular Oakley Gascan and Fuel Cell sunglasses. Constructed from Oakley’s amazing O-Matter material, they’re strong, lightweight, and flexible. The large Oakley metal icon accents are embossed on the temples and the three-point fit ensures they’ll stay put. Perfect for medium to large faces, the Oakley Crankshaft sunglasses are a great choice. This frame is also available with polarised lenses, which, along with the standard Plutonite lenses, block 100% of UVA, UVB, UVC and harmful blue light up to 400nm.
