The 90% cotton 10% polyester TMNT Shredder Grey T-Shirt is soft...like, way softer than a shirt featuring Shredder. One might expect that the central baddie of the Teenage Mutant Ninja Turtles would have a shirt made of razor blades! The Shredder leads the Foot Clan in New York which essentially consists of a bunch of bad ninjas who hate pizza and the word, 'dude'. That's what I understand anyways. Get the TMNT Shredder Grey T-Shirt and show those Turtles what-fer!
