Frequently Asked Questions

Will I get too hot in it?

It's made to keep you warm on the couch through fall and winter, so yes, it's cozy. The relaxed fit lets air move around, though, so you won't get that stuffy feeling you get from tight pajamas. Most customers start reaching for theirs as soon as the weather turns.

How do I wash it?

Machine wash cold on the gentle cycle. Turn it inside out and toss it in a mesh laundry bag to protect the hood. Skip the dryer and the iron. It air-dries fast and fluffs right back up on its own.

Is it unisex?

Yes, every onesie we make 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.
