Women’s Demogorgon Onesie for haunting the sofa after dark

Hawkins, Indiana, somewhere in the eighties. A gate opens in the basement and the most feared creature in Stranger Things climbs out looking for something to eat, preferably popcorn. This Demogorgon onesie for adults reproduces the monster in thick grey flannel veined with black, the hood blooming into a red petal head lined with cream teeth. The series logo is stitched on the chest, ribbed cuffs close the sleeves and ankles, and two front pockets keep the remote within claw’s reach at all times.

Own the Upside Down in a Men’s Demogorgon Onesie

Nobody forgets the first time that faceless head opened on screen. The adult Demogorgon onesie lets fans wear the nightmare like pyjamas, with a smile and a relaxed cut roomy enough for a full season in one sitting. The word DEMOGORGON arches across the back over a red petal emblem, the zip runs straight down the front, and the thick flannel keeps the chill of the Upside Down far away. Halloween night, themed watch party or a creepy cosy Sunday, this kigurumi is ready to hunt. Add it to the basket and turn the lights off.

The rest of the horde

Dress a smaller member of the family in the kids Demogorgon onesie for a matching look at home. Anyone who loves this design will also enjoy the Mothman onesie. The Halloween onesies collection gathers every other creature of the night.

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.
