Meet your new favorite outfit.

The Wumple Onesie is what happens when a hug becomes clothing. Wrapped in ultra-soft plush fleece from hood to toe, it's built for couch marathons, midnight snack runs, and answering the door with zero shame.

The hood comes complete with Wumple's signature messy mop and big goofy eyes, and the front kangaroo pocket — featuring a baby Wumple face of its own — holds your phone, your snacks, or your dignity (whichever fits).

Why you'll never take it off:

  • Ultra-soft plush fleece that gets cozier with every wash
  • Machine washable, shed-proof, and snack-crumb resistant
  • Relaxed unisex fit — roomy enough for maximum sprawl
  • Baby-Wumple kangaroo pocket for essential storage
  • Sizes S–XXL, because everyone deserves to be a Wumple

One zip and you're 40% more huggable. Science*.

*Not science.

Bought the green one to match my boyfriend's black one. We answered the door together and the delivery guy lost it. 10/10.

SO soft. The little pocket Wumple gets more compliments than any outfit I've ever owned.

Got the Family Pack for movie nights. My kids refuse to wear normal pajamas now. Zero regrets.

The with-shoes version is elite. My feet have never known such luxury. Sized up for extra bagginess like they said — perfect.

Washed it five times already. Still stupidly fluffy. How.

Wore it to a costume party and won. Wore it home after and won again (comfort-wise).
