Girls Rilakkuma Onesie for the laziest afternoon in San-X history

Rilakkuma has one talent, and it is relaxing. This Rilakkuma onesie for kids passes that gift to the next generation in warm golden plush, with a soft white belly running down the front and a hood that carries the bear’s sleepy face, two small ears on top and a round nose in the middle. A tiny tail bounces at the back, and orange cuffs keep the sleeves and ankles in place while the child masters the fine art of doing nothing before dinner.

Pancakes and pillows in a Boys Rilakkuma Onesie

Kaoru’s flat would be quiet without the bear who eats her pancakes, and these kids Rilakkuma pyjamas bring that same gentle chaos home. The plush fabric feels like a cuddly toy, the roomy cut allows real rolling on the carpet, and the front opens easily so a kid can get in without help. A sleepover, a rainy afternoon or a costume day at school, comfort never stops. Add it to the basket and watch bedtime become the favourite part of the day.

The whole San-X family naps here

The Rilakkuma onesie lets a parent join in with the very same look. For a playful pair of siblings, the kids bear onesie is the natural companion. Finally, browse the whole kids onesies collection for more playful costumes.

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.
