5.11 Soar Polarized Sunglasses are an updated version of the classic Aviator frame and provides extreme peripheral protection. The polarized smoke lenses protect eyes from harsh glare and exceed ANSI Z87.1-2003 and EN 166 (F) High Velocity Impact Safety and Optical Standards. Polarization dramatically reduces glare. T-Shell coating means resistance to scratching, cracking, and crazing. Selenite polycarbonate is die-cut to produce lenses without distortion from any angle and is ten times more impact resistance than glass or resin lenses. Frames are built with Grilamid TR-90, a homopolyamide nylon characterized by an extremely high alternative bending strength, low density, and high resistance to chemical and UV damage. They are virtually indestructible.
