Enjoy the sporty design and high performance optics of the Revo Guide Small Polarized Sunglasses, even if you're not guiding trips into the wilderness on a daily basis although these work great for that to. These streamlined, lightweight shades feature a curved stem design, enlarged arm vents, and Motion Fit system for a secure, non slip fit when you're skiing, boating, and engaging in high octane activities. The sunglasses' Eco Use frame transforms castor bean oil into nylon for a more sustainable pair of shades that are extremely lightweight and flexible. Giving you precision optics, the sunglasses' lightweight Serilium polycarbonate lens provides crystal clear vision, especially on the water, with its high contrast polarization. In addition, the Element shed hydrophobic coating keeps dirt, oil, and water from sticking to the lens when you're getting dirty on the trail or lake.
