The Oakley A Frame Polarized goggle is part of Oakleys first generation of polarized goggles. For bright days, these are the goggle of choice if you already appreciate polarized glasses. The A Frame is built to withstand long-range solar attacks and short-range meteorological events. Polarized lenses reduce glare from icy, shiny surfaces. Dont worry, you wont lose any of the A Frames famous optical clarity or wide peripheral view. A triple layer of face foam insulates and provides maximum comfort.
