The 100% polyester Superman Kids Costume Riveted Pajama Set w/Cape will help instill in your child a deep sense of morality and justice...I think. It is either that or they'll start jumping off the furniture to perfect their Kryptonian powers! Kryptonian children get their power from a yellow Sun...Earth children gain their powers from sugar! That would be my guess why they aren't allowed to have any soda. Anyways, the Superman Kids Costume Riveted Pajama Set w/Cape is a flame resistant PJ set created in the likeness of DC Comics' flagship character, the Man of Steel! It's a bird...it's a plane...it's your child in the Superman Kids Costume Riveted Pajama Set w/Cape!
