Oakley SI Quarter Jacket Tactical Reviews, Deals, Problems and Guides

With an interchangeable lens system and an aggressive frame design, the Oakley SI Quarter Jacket delivers ultimate visual performance in any setting. The Plutonite lenses filter out 100% of all harmful UV rays, and are treated with an Iridium coating to reduce glare and fine tune light transmission to suit your environment. An 8.75 base lens curvature provides ultimate side protection and enhances your peripheral vision. The lightweight O Matter frame uses controlled flexibility to withstand environmental extremes, and uses an Unobtainium grip to hold the glasses in place at all times, even when perspiring. Designed with Oakley's signature Three-point fit to hold the lenses in precise optical alignment, these glasses are made to perform and look great anywhere.
