Now nightmares will face the wrath of the Last Son of Krypton with the 100% polyester Superman Belt & Symbols Kids 2-Piece Pajama Set! Not that your child is actually Kryptonian it is just that nightmares don't know any better...they see the red, yellow, and blue color scheme and they assume that the Man of Steel is on duty! Flame resistant, the Superman Belt & Symbols Kids 2-Piece Pajama Set has a shirt that looks just like the costume and a pair of pants decorated in a bunch of red and yellow symbols.
