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 loves this swaddle! He was born at 36 weeks, so he is on the smaller side and the 0-3 month swaddle works perfect! I will be buying more! Thank you Ben+James!!

Love it!!!

Tried this swaddle for the first time last night after using some other wrap/Velcro ones. We LOVED the Jack swaddle. Love that it’s so easy to put on but also that it’s not bulky. Ordering another one right now!


My son did not like this at all...

Runs small for accurate sizing

The newborn one I feel isn’t accurate on sizing. Way too small for my 8 lb one month old.. I ordered a size up to and that one fits more realistically than the other one for his size. Love the sleep sacks, just wish sizing was more accurate.


Comfortable material. I really wish my little Houdini would stay in the swaddle but if you have a calmer sleeper this would probably be the perfect swaddle for you.
