The Spiderman Kids Ultimate Spidey Pullover Pajamas is made out of a soft 100% polyester and highlights Marvel's Spider Man in dazzling colors! The shirt part of this fantastic PJ set is a cavalcade of contrasts and imagery boldly presenting everybody's favorite neighborhood Spider, while the pants show off several smaller images of Spider Man and...um...spiders! Spiders with Spider Man? I'm afraid you lost me - I never expected to see SPIDERS on a Spiderman Kids Ultimate Spidey Pullover Pajamas! Of course I am kidding and this set is sure to please any burgeoning Spider Man fan!
