In that case, you receive an email with a tracking number for each package. These emails may arrive a few days apart.
Orders are prepared and shipped within 1 to 2 business days after you receive your order confirmation email, as long as the item is in stock.
Business days are Monday through Friday, excluding public holidays.
Orders placed on a weekend or holiday begin processing the next business day.

We do everything we can to get your order to you as quickly as possible. To learn more, see our Shipping Policy.
PRODUCT
We recommend using the size chart on each product page. Your height is the most reliable guide. If you are between two sizes, size up.
They’re made to keep you warm on the couch through fall and winter, so yes, they’re 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.
Depending on the style, our onesies are made from either flannel or fleece (brushed polyester). These fabrics are chosen for their soft feel and their resistance to pilling. They are not scratchy and work well for sensitive skin.
The zipper or button closure opens far enough to get undressed quickly and easily. Some styles also have a zipper in the back, which makes bathroom trips even easier. When a style has one, you can see it in the product photos.
Machine wash cold on the gentle cycle. Turn them inside out and toss them in a mesh laundry bag to protect the hood. Skip the dryer and the iron. They air-dry fast 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.
