Whether the Raen Arlo Sunglasses inspire you to pick up playing guitar or simply shield you from the sun's harsh rays, these shades are distinctly dapper. Handcrafted using a zyl acetate frame, the Arlo's masculine silhouette is inspired by styles from the '50s and '60s, while the Carl Zeiss Vision CR-39 lenses offer full UVA and UVB protection.
