Iron Man MK IX Armor Stark at work This may look like a standard t-shirt, but it's actually the Iron Man Mark IX suit. This latest version is much lighter than all previous versions, featuring a flexible interior with knitted cotton exterior. Unlike the Extremis version, the movement with your body does not require you to inject carbon nanotubes into your brain. The chest-mounted uni-beam is powered by photons, which it collects and then disperses when the wearer enters a dark area. For all body parts covered by the Mark IX's new form factor, the suit provides protection from adverse weather conditions, UV rays, and temperature extremes. It is designed for up to two days of use inside Earth's atmosphere, although after the first 12 hours of use its effectiveness is reduced. After 24 hours, it begins to act as a repulsor. The Iron Man Arc Reactor Shirt has three components: the t-shirt, a light panel with a long cable, and a battery box. When fresh batteries are in the battery box and the unit is switched on, the Arc Reactor shines brightly. So this particular arc reactor isn't going to keep shrapnel from working its way into your heart or power your repulsor beams. What do you expect for under $30? A shirt that glows? That, we can provide.
