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.
