Down the chimney in a Women’s Santa Claus Onesie this December

A mince pie and a glass of sherry wait by the fireplace, the reindeer are stamping on the roof, and the most famous suit in the world finally comes as onesie pyjamas made for the sofa. This Santa Claus onesie for adults keeps every detail of the legend: bright red fleece, snowy white trim at the cuffs and hem, a black belt with its buckle, pompom buttons down the front and a pointed hood tipped with a white pompom. Ho ho ho comes naturally after that.

Deliver the presents in comfort with a Men’s Santa Claus Onesie

Wearing an adult Santa Claus onesie on Christmas morning changes the whole ceremony. Presents feel bigger when the real thing hands them out, kids believe a little longer, and the grown-ups laugh a lot louder. The fleece stays warm from the first cup of tea to the last mince pie, and the loose cut leaves plenty of room for a cushion belly. Put it on the list early, and the sleigh will be ready long before the stockings are hung.

The North Pole crew

Little helpers can match the grown-ups in the kids Santa Claus onesie. The Mrs Claus onesie completes the couple for a card nobody will forget. Elves, snowmen and reindeer report for duty in the Christmas 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.
