The alchemy of Oakley C-5 liquefies metal compounds into a durable performance alloy. All-day comfort is enhanced by low-mass architecture and a proprietary three-point fit. Earstems are sheathed in soft Unobtainium® to improve adhesion with moisture. Oakley lenses are available in thirteen color hues and a power range of +3.00 to -9.00 for the O2 series.
