The 100% polyester Nightwing Sublimated Costume T-Shirt is the official way to protect Bludhaven. That and an intense training regime from DC Comics' Batman. You already went through that whole ordeal right? Thank somebody that you had those acrobatic lessons while you were little! With an all over print the Nightwing Sublimated Costume T-Shirt is one super sweet costume shirt for fans of Dick Grayson!These are not your typical shirts; sublimation is a viable and durable solution to the industry standard of ink jet heat transfers. The sublimation process takes a large sheet of ink soaked paper heated to ridiculous temperatures which causes the ink to literally bind to the fabric. This causes the shirt's image to become amazingly resilient to the ravages of time!This technique can result in small imperfections generally around the armpit seams and stretched spots on the shirt. It is something that is intrinsic with this process but it makes each shirt wholly unique.
