Scout Trooper
I scout for details...
Oh yeah, I forgot about the belt lol. And that's got a massive pouch.Most likely he keeps the computer in his Batmobile. Backpack probably has his boots with shin covers, utility belt, gloves and gauntlets, cape and cowl. He wears the entire suit underneath. The outfit seeing how baggy it is to a degree. That jacket is pretty big on him in film.
He's usually got his bike. But Idk how much he keeps stowed in that thing.
