The River Polarized Acetate Sunglasses combine serious sun protection with timeless style. Inspired by the iconic shape of our classic wayfarer , these sunglasses offer a slightly smaller frame and more rectangular eye shape. They’re also lightweight for all-day comfort, and because they’re polarized, they’ll protect your eyes from glare. Bonus: The acetate frames are a plant-based alternative to conventional plastics made from petroleum, so you can feel good about wearing them too.
