Cowabunga in Comfort
Sometimes you want to fight crime. Sometimes you want to nap. Sometimes you want to eat an entire pizza and pretend you might do the other two later. The Adult TMNT Michelangelo Costume Onesie understands all of that. It's cozy, goofy, and officially licensed for both ninja action and full couch-mode. Basically, it's everything Mikey would wear if he had access to central heating and streaming apps.
Yes, it's technically a costume. No, we won't judge you for wearing it on laundry day.
Product Details
This one-piece onesie is made of soft, low-pile minky fabric that feels like you're being hugged by a crime-fighting blanket. It zips up the front for easy wear and features rib-knit cuffs at the wrists and ankles to keep the fit snug, warm, and surprisingly pajama-adjacent.
The suit is printed with Mikey’s iconic turtle torso, orange elbow and knee wraps, and his signature belt—complete with a big "M" on the front to remind everyone which party dude you are. The attached hood has his orange bandana, printed eyes, and even little side ties, so your head is in full ninja turtle mode the second you pop it up.
The Master of Chill-itsu
Whether you're hitting a costume party, rewatching old episodes, or just showing the world that orange is your personality color, this onesie brings full Michelangelo energy without sacrificing comfort. It's soft and ready for some ninja action with your Teenage Mutant Ninja Turtle brothers... or some late night snacks. Probably snacks. Definitely snacks.
