Women’s Blue Shark Blanket Onesie wraps you from hood to tail

This one is not a pyjama, it is a wearable blanket shaped like a shark. You slide into the blue shark blanket onesie for adults feet first, the tail closes over your toes and the open jaw sits above your head with its white teeth framing your face. The plush flannel is lined all the way through, so the warmth is immediate.

The blue grey back and the white belly follow the shape of a real shark, and the two side fins double as sleeves, which is what lets you hold a mug or a controller without letting the cold in. There is no zip and no buttons to fight with, you simply step in and pull it up.

Sofa evenings with the Men’s Blue Shark Blanket Onesie last longer than planned

An adult blue shark blanket onesie solves a problem that a plain shark blanket hoodie never quite does. A blanket slides off the moment you move, a onesie has to be put on properly, and this sits exactly in between. It stays on while you get up to refill the kettle.

It has also become a favourite on video calls and streams, where the jaw over the head is instantly recognisable. Order it for a cold flat, a long winter or someone who complains about the heating more than anyone else you know.

The same shark in other shapes

The pink shark blanket onesie offers the identical shape in soft pink and white. If you want sleeves and legs instead, the blue shark onesie is the classic one piece. Both sit side by side in the shark 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.
