Whether you strut on the rivers, down the trails or through town the SunCloud Sashay Sunglasses bring style and UV protection to every adventure. Suncloud polarized lenses use advanced technology to selectively filter horizontally reflected, visually interfering light waves known as 'glare,' resulting in superior visual clarity, definition, color transmissions and optical comfort. Lenses are manufactured using injection-molded optical grade Polycarbonate material to ensure exceptional clarity and create a lightweight lens with high impact resistance for added protection. Integrated filters in the lens provide 100% protection from the sun's harmful UVA/B/C rays. Tough and light Evolve™ frames are constructed with over 50% bio-based materials. Microfiber storage bag (included) doubles as a cleaning cloth to wipe any smudges off your lenses. A 4-base lens curvature creates a medium fit that's flatter against the face. Lifetime Warranty.
