Turtle Power! Thoroughly motivated by the Teenage Mutant Ninja Turtles, the 60% cotton 40% polyester TMNT Costume Hooded Kids Double-Sleeve T-Shirt is (this is crazy) a double-sleeved, hooded, and masked t-shirt! That's a lot going on, but your child will be able to keep pace...after all, they are freshly infused with pizza and elite ninja skills taught to them by a talking rat. Oh, they don't have a rodent martial arts instructor? Argh. Awkward. The TMNT Costume Hooded Kids Double-Sleeve T-Shirt's hood-mask-mesh hybrid is made from 100% polyester and is a great way for your child to show off their enduring affection for the heroes in a half shell!
