The 100% polyester Spider-Man Web Head Space Dye T-Shirt features the iconic mask of everyone's favorite web-slinger in a soft and light space-dyed t-shirt. What is space dye? I believe it's what the Future Foundation made their suits out of. Of course, I suppose it could always be a dye technique that adds a neat stripey, heathered effect to the shirt, but Future Foundation suit material has slightly more wow factor, so I went that route. Either way, this is a cool looking t-shirt. Support the slinging of webs with the Spider-Man Web Head Space Dye T-Shirt!
