This is my own personal concept design for a more realistic and tactical Batman suit. (Just for fun. I don't work for DC Comics).
I wanted to design a suit that seemed more realistic for a younger Batman. Not super teched up, utilizing different types of lightweight body armor mixed with some hard armor components. Some parts are inspired by various designs from comics, movies, and video games, as well as some of my own ideas. Also added a few extra places for Batman to store his gadgets, just to make it seem more tactical. The Batarangs and Bat-knife on his arm and shoulder allow for easier access during combat (he doesn't have to drop his guard in order to get them).
I included a version with some explanations of the different components, as well as my initial sketch.
