For outdoor adventurers on a budget, the SunCloud Mayor Sunglasses get our vote! Lightweight frames, polarized lenses and a friendly pricetag, that's a trifecta that's hard to beat. 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. Injection-molded frames are crafted from optical grade Grilamid TR-90 Nylon for a quality fit, flexibility and lasting durability in all environmental conditions. 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. Microfiber storage bag (included) doubles as a cleaning cloth to wipe any smudges off your lenses. Lifetime Warranty. SunCloud Mayor Sunglasses
