The Yuba is an easy-to-wear unisex style that looks good on just about everybody. Consistently one of the top pairs we recommend to our community, the Yuba is a lightweight and versatile style that's a bestseller for good reason.We designed these shades in collaboration with fellow San Francisco outdoor brand Huckberry, and named it after the mighty Yuba river in the Sierra Nevada mountains of California. To us, the Yuba is a state of mind that reminds us of weekend adventures with good friends.
