The 50% polyester 50% cotton Spiderman Metallic Ink Kids Grey & Red T-Shirt is what happens when a dense crystal fog rolls over New York City. It binds to his webbing and his logo! Don't ask me where 'crystal fog' comes from either because there are a ton of Marvel heroes in NYC...it could be something from Dr. Strange or DareDevil or the Fantastic Four or something! Still, the Spiderman Metallic Ink Kids Grey & Red T-Shirt is a classy shirt with red sleeves, a heather grey body, and a lot going on!
