Women’s Greninja Onesie moving through the night without a sound

A ripple on the pond, a blur between the trees, and a shuriken made of water splits a leaf in half. By the time anyone looks up, the ninja of Kalos is gone. This Greninja onesie for adults gives the stealthy frog its full gear: navy blue fleece, a cream belly, white bubbles on the limbs and pale blue star blades on the thighs. The famous pink tongue wraps around the neck like a scarf, under a crested hood. No smoke bomb needed for an exit this clean.

Stealth, speed and a Men’s Greninja Onesie for the final battle

The adult Greninja onesie is a favourite of trainers who like to win quietly. The onesie costume keeps muscles warm between two matches, the button front opens quickly, and the wide legs leave room for a crouch, a leap or a nap on the sofa. From a tiny Froakie to champion of the league, the whole story lives in one outfit. The tongue scarf alone is worth the photo, and the star blades on the thighs settle any doubt about who trained hardest. Strike first, and add the fastest water type to your team.

Rivals worth the fight

The Lucario onesie steps up as the sparring partner every ninja needs. Starters from every region train in the Pokémon onesies collection. Shadows from other stories slip in among the adult onesies.

Frequently Asked Questions

They’re made to keep you warm on the sofa through autumn and winter, so yes, they’re cosy. The relaxed fit lets air move around, though, so you won’t get that stuffy feeling you get from tight pyjamas.
Machine wash at 30°C on a gentle cycle. Turn them inside out and pop them in a mesh laundry bag to protect the hood. Skip the tumble dryer and the iron. They air-dry quickly and fluff right back up on their own.
Yes, every onesie we sell is unisex. The roomy cut works for men and women alike, our kids’ styles fit girls and boys just the same, and our baby sizes are cut the same way for everyone. Just check the size chart to find your fit.
