Want to know why Superman wears a cape? We think it's because of the dramatic effect it causes when he flies on to the scene. We used to think it had to do with some kind of aerodynamic properties to get increased speed during flight, but various scientists have told us that capes don't work that way. (Except maybe in the DC comic book universe). That's how we settled on the dramatic effect theory. It flaps and flows in the wind, adding a heroic style to his grand entrance. If you want that dramatic effect for your Superman costume, then you're going to need a cape.Oh! Looky here! We just happen to have Superman cape available for you. This Dawn of Justice Superman Cape is a deluxe cape that recreates the one worn by Henry Cavill in the Batman v Superman movie.
