This is a 100% cotton Superman symbol t-shirt with but with just the red outline. We call it the Superboy shirt because it's what the new version of Superboy wears in the comics. Liked for its lower tone and simplistic look...but people will give you bonus points for knowing it is Superboy! On the bright side of things, I don't think that Superboy Prime is interested in the Superboy Red Symbol T-Shirt but I could be mistaken. Ever since that guy punched reality I've been really confused with current continuity!
