Made from flame resistant 100% Polyester, this 2-piece, simulated Spiderman costume pajama set for the wee-ones features a top illustrated with the likeness of Spiderman's costume (the symbol, the webbing "grid") and those awesome (simulated) web-wings spreading between the arms and side, made from a sheer, black material! The bottoms are full length, featuring a covered, elastic waistband for a comfortable fit!  These Spiderman pj's are great for kids who appreciate heroes taking a break for a good, long cry.
