The Spy Polarized Helm Sunglasses aren't for the faint of heart—their aggressive lines and high-end optics combine visual clarity with striking style that's ideal for everything from days at the beach to recovery days spent in town. UV-blocking lenses filter out harmful rays from the sun, while polarization reduces glare from water, roads, and the hood of your car.
