Teenage Mutant Ninja Turtles Adult Leonardo Costume Onesie | Nickelodeon Costumes
Lead the squad in style and comfort with the Teenage Mutant Ninja Turtles Adult Leonardo Costume Onesie from Nickelodeon Costumes. This officially licensed TMNT outfit lets you channel Leonardo's leadership and ninja poise while you kick back in super-soft loungewear. Perfect for movie nights, parties, and cosplay, it blends heroic look with everyday comfort.
Made from soft, low-pile minky fabric, it's basically costume-ready lounge wear. A full front zipper makes it easy to wear, while rib-knit cuffs keep the fit secure during training, meditations, or couch sessions. The printed details showcase Leo's blue wraps, a brown belt with a bold L, and a hood with his blue bandana, printed eyes, and side ties for full shell squad authenticity.
Whether you’re leading the team at a party or practicing slow-motion sword moves in the mirror, this Leonardo onesie brings turtle power with zero shell discomfort. Officially licensed and designed for comfort-first cosplay, it’s the ideal pick for adult fans who want to lead with confidence and nap like a pro.
