Zeal Ace Polarized Sunglasses Bombay Brown/Copper, One Size

We all lose our fair share of sunglasses, but if you're worried about all those missing pairs ending up in that giant plastic gyre in the Pacific, then you should switch to the Zeal Ace Polarized Sunglasses. Featuring a frame made from 100% US-grown cotton, they are the world's first biodegradable sunglasses. The cotton frame is surprisingly rigid and durable so they still feel like a normal pair of shades. Zeal also made sure the entire sunglasses were free of crude oil-based plastics, so the Ace also features E-llume polarized lens, which are made from a plant-based material called Z-Resin to eliminate the need for harmful petrochemicals in the manufacturing process.
