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.

These were the best swaddles I ever bought I love them. Material,softness confines everything 👍

Christopher Borcsa
Very nice material

Soft and comfy love it


I’m unhappy about this product

Marina Chester
Not my fave

My little one can get his arms pretty much out of This and I feel like it disturbs him when I put it on when he’s sleeping. I feel like I don’t want to change a diaper with it on because ends up being too much fabric everywhere with baby onesie bunched up and the sleep sac. I like my large cotton cloth to wrap him in because it’s quicker and I can adjust tightness. Sad I can’t return because I bought 2 and now am using what I had prior to these.

Our preemie newborn loves his Jack! It’s snug, but still allows for some arm movement, which he likes. The material is a dream and the stretch is on point! Thank you, thank you!!
