It’s probably not going to be as durable as the armored suit he wore when fighting Kal-El in Batman v Superman: Dawn of Justice, but the tradeoff is that he’ll be able to move more quickly than if he was in that clunky armor.
During the Justice League set visit this past summer, designers hinted to reporters that Batman’s tactical suit would offer more protection compared to his regular suit.
This suit should also come in handy if he accidentally finds himself too close to an explosion…not that he should make a habit of standing near those.
So of all the entries on this list, this one is a guaranteed improvement, which is good, since Steppenwolf and his Parademons hit a lot harder than your average street criminal.
