Cowabunga, dude! The Turtles are back. Leonardo, Donatello, Raphael, and Michelangelo are four mutant turtles, trained in the art of "ninjutsu" by their sensei, Master Splinter. This tee has a retro neon design of our favorite turtles in a half shell on the front, followed by a two-tone tie-dye style with tones of purple and blue. It's 100% cotton for durability.
