Women’s Gorilla Onesie for ruling the living room jungle

High in the misty mountains, a silverback lowers its shoulders and the whole forest holds its breath. This gorilla onesie for adults brings that quiet authority home in deep black flannel, with a grey muscle panel stitched across the chest that turns any torso into a wall of abs. The hood carries the full face, furrowed grey brows, a wide grin of white teeth and a shaggy black mane on top. Hands disappear into the side pockets, and the room suddenly belongs to the biggest ape in it.

Beat your chest in a Men’s Gorilla Onesie tonight

Every group costume needs a heavyweight, and the adult gorilla onesie volunteers. The drop-crotch cut leaves space to lumber, squat and knuckle-walk across the carpet, ribbed black cuffs keep the sleeves and ankles in place, and the zip hides down the centre of the muscle panel for a quick change back to human. Halloween, a stag weekend or a Sunday of nature documentaries in costume pyjamas, the mountain king is ready. Add it to the basket and claim the biggest spot on the sofa.

The rest of the troop

The kids gorilla onesie lets the little ones share the very same design. For a themed pair with a friend, the monkey onesie is the natural companion. More furry friends are waiting in the animal onesies collection.

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.
