This is the ultimate in Iron Man costumes. Why go with a regular jumpsuit when you can get something that really looks like the real thing? The Kid's Iron Man Mark 42 Muscle Light Up Costume can do so much more with its added features. The Kid's Iron Man Mark 42 Muscle Light Up Costume looks just like the suit Iron Man wears in the three Marvel films and features a fake muscle chest and arms to look like a really tough super hero and Iron Man's life saving arc reactor really lights up! Included in this great package is also a character headpiece, the Iron Man mask. The mask has eye and mouth cut outs so it can be easily seen through and breathing is no issue.
