Women’s Jake the Dog Onesie for stretching out across the Land of Ooo

Jake can stretch into any shape he wants, and after a long day, most people just want to stretch onto the sofa. This Jake the Dog onesie for adults makes that the whole plan, in soft yellow plush from the hood to the toes. The hood carries Jake’s wide eyes and lazy grin with two small ears on top, a tiny Finn is embroidered on the chest right where a best friend belongs, and a stubby tail sticks out at the back.

Mathematical comfort in a Men’s Jake the Dog Onesie

Adventure Time fans know the treehouse is the cosiest place in Ooo, and the adult Jake the Dog onesie brings the treehouse to the bedroom. The plush fabric stays warm through a full season binge, the roomy cut leaves space for bacon pancakes, and the front closure opens fast when BMO calls for a game. Convention weekend, a Halloween costume or a lazy Sunday with the whole crew, these character pyjamas fit the quest. Add it to the basket and stretch into the evening.

More companions from the treehouse

The dog onesie makes a perfect partner for a matching duo. Finally, browse the whole adult onesies collection to find another design to love.

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.
