It is important to teach your children about the glory that is Adam West...and the awesome 60% cotton 40% polyester Batman Dark Knight Kids Double-Sleeve T-Shirt! Not even Adam West could explain how fantastic this great double-sleeved t-shirt is! Whoa, that's entirely too many hyphens. Still, the Batman Dark Knight Kids Double-Sleeve T-Shirt is right to the point; an image of the Dark Knight swinging into action above his logo and a Gotham logo! Hooray! Makes you wanna do the 'Na-na-na-na-na Batman' song, doesn't it?
