Co-designed with snowboarding champion Shaun White, MONTEFRIO utilizes patented XYZ OPTICS to maintain clarity at all angles of vision, even with six-base lens curvature. That means you get a crystal clear peripheral view that's wide open, plus wrap-around protection against sun and wind. UV increases at altitudes where Shaun competes, but the pure PLUTONITE lenses filter out every ray, including UVA, UVB, UVC and harmful blue light called HEV. MONTEFRIO sunglasses offer the comfort of lightweight O MATTER frame material and the durability of impact protection that meets all ANSI Z87.1 standards.
