EXCLUSIVE AT MR PORTER. Whether it's quality eyewear or premium tailoring, only the most refined designs are worthy of a place in a Kingsman agent's wardrobe (and our namesake in-house label). Made by London-based eyewear brand Cutler and Gross, these early 1900s-inspired sunglasses are crafted from lightweight tortoiseshell acetate and fitted with tinted grey lenses. The round frames are universally flattering and reminiscent of vintage styles.
