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.

Absolutely Amazing!!!!!!

This sleep sack is the only thing that makes my son sleep ALL NIGHT!!!! Someone got me one for my baby shower and I didn’t know how to properly use it at first but once I figured it out it was THE BEST THING EVER! We tried lots of other swaddles and he managed to wiggle his arms out and he would ALWAYS wake up because his startle reflux is so bad. This sack is amazing and so easy to use. I ordered 2 more in a bigger size and we couldn’t be happier and are so happy that he started sleeping through the night at just 8 weeks old. (He is now 11 weeks!). Thank you Ben & James!!!!!

Literally a cheap Tshirt and is really small not comfortable at all. Would not recommend

Karen, so sorry to hear you weren’t happy with your Jack Swaddle Sack. We made it with a light weight luxury jersey knit fabric to keep baby from over heating in warmer climates and summer season. We chose this fabric because it’s buttery soft fabric with tons of stretch. And sorry your sleep sack didn’t fit like you had desired. We offer 3 different sizes for this exact situation. I’d be happy to set you up with our 6-9 month size if you’d like to give it one more try?
