Frogskins LX combines classic cool with the comfort of a hand-made frame honed from lightweight yet durable acetate. Sculpturally integrated hinge mechanisms give it a modern touch, and the interior facing is lavished with a print of personality. Signed with metal logos on the earstems, this salute to time-honored style is today's look of originality. Oakley HDPolarized lenses block 99% of reflected glare. All lenses are made of pure Plutonite that filters out 100% of all UV, not just UVA and UVB.
