The Cosmopolitan is chic and refined. It is a timeless look with its vintage keyhole nose to its retro round frames. The Cosmopolitan is at home at the beach and in the country, but really finds its mark in the daily hustle and bustle of Urban life. The on-point styling will dress up or down with you seamlessly, so the Cosmopolitan is perfect for your 9am coffee meeting to your 5pm trail hike and everything in between. The Cosmopolitan in Black Walnut is like a good pair of blue jeans, in that, they will compliment just about any outfit. Black Walnut's subtle dark brown and wide wood grain pattern have made this wood a favorite throughout the ages. A total of 5 cross-grain layers of Black Walnut hardwood make up its frame, so the Cosmopolitan is strong and sturdy and ready for its active lifestyle. Simply stunning, one won't regret choosing this pair. This particular style tends to flatter small to medium size faces best, but will accommodate larger because they come standard with stainless spring hinges which allow the temples to bend as a slight double action hinge. This ensures a comfortable, secure fit for face sizes small to large. If you couple that with the fact that Wood Worn wooden sunglasses weigh on average over 30% less than their traditional plastic or metal counter parts, then you have shades you can happily wear all day long. And let's not forget, the Polarized lenses rated at UV400 which block out 100% of all harmful UVA and UVB rays, that come standard with all Wood Worn sunglasses. Finished with a scratch resistant coating and highly impact resistant, these lenses are made to live in.
