The Jack Sleep Sack is the simplest way to swaddle a baby. It requires no wrapping, no tucking, no zipping and no Velcro. It slides on like a shirt and and keeps baby snug and secure all night long.

How to use: You simply put it on by sliding it over baby's head like you would a shirt. It features interior arm pockets to keep baby's arms by their sides through the night. To use the pockets, slide your arm into the sleep sack from the bottom and inside the pocket. Then grab your baby's arm and gently pull their arm into the pocket. This pocket prevents baby's arms from escaping and waking themselves up. The bottom of the sleep sack is flared for the benefit of diaper changes. It makes for easy access to the diaper so no un-swaddling needs to happen during those late night changes. Removing the sleep sack is easy, simply stretch the collar over baby's shoulders and pull off over their body. Removing over the body is convenient in the case of a blowout.


-Simple: Slides on like a shirt and removes easily.

-Interior Arm Pockets: To keep baby's arms secure and by their side all night.

-Flared Bottom: Easy access for diaper changes, night time, or nap time. 

-Lightweight: This one layer swaddle is secure without bulk, breathable, extremely soft, and super stretchy.  

-Stretchy Collar: The collar stretches for easy over the body removal.

Sizing: These swaddle Sacks are true to size, so order the same size your baby wears in clothes. 

Safety: Discontinue use when baby shows signs of rolling over.

My baby gets out of every single swaddle. Not this one!! My favorite!! Super soft


Super soft and stretchy!

Jack Sack rocks

We have a newborn and use this every night! We started using it at the hospital and he loved it. We ordered 2 more in case any are dirty we always have one on hand. Super soft and stretchy. Works with arms tucked in or out. Easy diaper change with swaddle on.


This is a wonderful product. Thin and breathable, with the added comfort of knowing it won’t slip over your babies face in the night as they wiggle around.


My son does not like his arms down the side like designed but I fold his arms across his chest and he loves it. Snuggles him but still gives some freedom.
