Made from Kevlar, quarter-inch Kydex plating and impact-resistant foam, Armatus Designs created a real life version of the Batman suit. It won't stop bullets or make you Bruce Wayne but it is stab- and slash-resistant, while still being pretty lightweight and flexible. I wouldn't recommend you putting it on and becoming a vigilante or anything.
But you could probably fight petty criminals with it on.
