\r\n\r\nAdmit it, you'd love a chance at being Tony Stark when he saves the world as Iron Man! Although you can only dream, you may be able to pretend when wearing this Tony Stark Light-Up LED Iron Man Shirt that contains its very own light-up Arc Reactor! While it may look like a regular black T-shirt, it's actually detailed like the Iron Man Mark IX suit that's much lighter than previous versions. It features a flexible interior with a knitted cotton exterior that has a chest-mounted\u00a0\u00a0uni-beam that is powered by photons. It then collects and then disperses when the wearer enters a dark area.

The shirt comes with three components: the shirt, light panel with a long cable and a battery box. When you place fresh batteries in the battery box and the Arc Reactor is on, it will shine brightly like the one in the movie. It also provides protection from adverse weather, UV rays and temperature extremes and requires three AAA batteries that are not included. It's machine washable except for the electrical components that can be removed from the shirt. Get it now at ThinkGeek for only $29.99.
