The 60% cotton 40% polyester Superman V-Neck Juniors Sleep Set may have a side effect of having a hologram of Russel Crowe following you around. Consider it like the next stage of smart phone evolution - soon we'll all have our own pocket Russel Crowe that teaches people how to use Phantom Zone Projectors or Genesis Chambers. The Superman V-Neck Juniors Sleep Set comes with a fitted v-neck for the ladies that is light blue with the red and yellow Super-symbol and also comes with a pair of red sleep pants coated with that very same symbol. You can make your own choice...to sleep in the Superman V-Neck Juniors Sleep Set!
