You can actually zip this thing all the way up and then look out of mesh eye holes where Batman's eyes are. I think this is kind of cool as a hoodie, but when you add the face to it, I get creeped out. But if you're ready to go fight crime*, you can spend a mere $75 and be well on your way! The Tumbler will set you back a little more, though.

*Do not actually go fight crime wearing this.
