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.

We love the sleep sacks. They are the best ever !!! They work for naps, bedtime and just everything. They are life changing.

Super helpful for newborn parents, it's the only swaddle that has kept our baby sleeping for multiple hours at a time overnight and they're super soft and have been a great gift

Best sleep sack ever

We will never buy another sleep sack again. These are literally our favorite. Not only does my baby sleep so well in them, but they are stretchy, breathable, and there is zero velcro. Zero velcro to make it hard to wash, that catches on other clothes, or that has to be cleaned out from catching the hair or little threads. All the praise hands for that.

We love these!

Best invention ever!

My little one sleeps so much better after using this sleep sack. The only thing that would make it better is to have a zipper on the side to make it easier for diaper changes at night.
