Taking the form of classic aviator shades, the Revo Groundspeed Polarized Sunglasses inject a retro vibe into your daily look. These sunglasses use Nickel Silver that's corrosion resistant and pliable enough to withstand drops and bumps. Ideal for your active lifestyle, the sunglasses' Motion Fit system provides stay put performance when you're boating or casting a line. Offering a truly custom fit, the adjustable nose pads bring all day comfort. The Serilium polycarbonate lens and high contrast polarization cuts glare off water, ice, and snow surfaces, to give you precise, crystal clear vision. In addition, the Element Shed hydrophobic coating keeps dirt, oil, and water from sticking to the lens.
