Stop your child from doing the rough Christian Bale Batman voice and have them start doing the robotic Bat-fleck voice with the Batman Vs Superman Kids Batman Caped Pajama Set! Made from 100% polyester, the Batman Vs Superman Kids Batman Caped Pajama Set comes with a detachable cape and emulates the look of the Batman costume minus all of the weaponary and armor. One really shouldn't sleep with that kinda stuff anyways.
