For your next fishing trip or hike around town be sure to grab the Revo Descend N Polarized Sunglasses. This rimless frame provides that extra needed peripheral vision with unobstructed views and glare-cutting optics and performance fit you’ll be ready for whatever your day brings you. These shades use an Eco-Use frame, transforming castor bean oil into nylon for a more sustainable frame that's extremely lightweight and flexible. The frame's Motion-Fit system optimizes the fit for stay-put performance; there's an included detachable leash/buoy to ensure these don't fly off your head. The sunglasses' lightweight Serilium (polycarbonate) lens offers clear vision, especially on the water, with its high-contrast polarization and anti-reflective coating. 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.
