First in the Pokédex and first choice, the Women’s Bulbasaur Onesie

Three Poké Balls on a lab table, one decision, and a lifetime of loyalty to whoever answered first. For many trainers, the answer had a seed on its back. This Bulbasaur onesie for adults honours the original grass starter in soft teal fleece scattered with darker blue spots, with a round green bulb stitched between the shoulders. The hood shows red eyes and little ears, and white claws tip the cuffs for a playful Vine Whip. Sunny days make it stronger, and so does a good snack.

A Men’s Bulbasaur Onesie grows on everyone who sees it

An adult Bulbasaur onesie brings a breath of spring to the coldest evening. These onesie pyjamas are cosy for a full rewatch of the first series, the button front is quick to fasten, and the loose cut feels as easy-going as the Pokémon itself. Fans spot the bulb from across the convention hall and smile. The spots catch the eye, the bulb catches the compliments, and the claws on the cuffs are perfect for a dramatic point at the screen. Plant this one in your wardrobe this season, and watch your collection of good nights grow.

The other starters

The Charmander onesie revives the oldest rivalry in the lab for a duo. All types meet in the Pokémon onesies collection. More legends of screen and game fill 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.
