One of the managers here is convinced that this super soft 60% cotton 40% polyester Transformers Prime Outline Red 30 Single T-Shirt is the coolest shirt...ever. I'm serious too, he won't stop talking about. Granted, he's a huge 'giant-fightin-robot' fan so chances are so are you. You are reading this description, aren't you? The Transformers Prime Outline Red 30 Single T-Shirt is a premium shirt featuring Optimus Prime, the leader of the heroic Autobots! The white outline image makes this red shirt pop! Too bad it isn't the sound effect.
