The Batman Fort Knocks are a must-have for any comic fan. This pair takes inspiration from the edgy darkness of D.C. Comics’ most popular vigilante, starting with black-to-gray fade fronts. The color scheme continues down each arm, where a swarm of bats fly over a black and gray background. Batman’s iconic yellow crest is prominent on the outside of each arm, while the Batman logo is displayed on the inside of each arm over a black and gray comic strip scene. Fort Knocks sunglasses feature a sleek fit with a 49 mm frame height, 148 mm frame width, 54 mm lens width, 21 mm nose bridge, and 139 mm temples for all-day comfort.
