SNOO Sack 5-Second Baby Swaddle
SNOO Sack has special wings that slip onto SNOO’s clips to secure babies on their backs and prevent risky rolling. This swaddle sack was created by Dr. Harvey Karp, America’s favorite pediatrician. Dr. Karp is the doctor whose 5 S’s started the Swaddle Revolution, so parents can rest easy knowing he designed every detail of SNOO Sleep Sack with baby safety—and parent sanity—in mind.

When using the SNOO sack with the baby’s arms in, it helps prevent the startle reflex and keeps the baby’s arms snugly wrapped. This can provide a sense of security and promote better sleep.


If you prefer to have your baby’s arms out or if your baby shows signs of wanting more freedom of movement, the SNOO sack can also be used with the arms out.

“#1 Swaddle” New York Times: Rated America’s best baby swaddle, our SNOO Sleep Sack was designed by top pediatrician and world’s leading hip-safe swaddling expert, Dr. Harvey Karp. Perfect for healthy, growing hips (International Hip Dysplasia Institute seal of approval).
100% Organic Cotton: Made from luxuriously soft organic cotton with special wings that attach to our SNOO Smart Sleeper to keep babies safely on the back. Includes extra-quiet Velcro for escape-proof security and 2-way zipper that opens from top or bottom for easy midnight nappy changes.
More Infant Sleep: Our baby swaddle sleep sack prevents startles and boosts babies’ sleep quality with special inner flaps that give the snug embrace your baby boy or girl loved in the womb. Arm openings can unsnap to allow for arms out. Great transitional swaddle for moving to crib with arms free independent sleep training.
“5-Second Baby Swaddle”: The Happiest Baby Swaddle is the easiest, safest, fastest, escape-proof baby swaddle wrap. It promotes self-soothing and keeps babies sleeping longer than other swaddles.
Prevents Overheating: Breathable mesh at shoulders and legs of baby warp reduce risky overheating. More secure and comfortable than other swaddlers, blankets, or baby sleepers.

So cute
Vibrant colours, very soft, high quality and great fit. It’s breathable and doesn’t retain stains
The best
Get a snoo, worth every penny!
Great fit, comfy, baby loves it.
I didnât realize when I bought this, that it was meant to go with a specific bassinet. I used it regardless as my sonâs current one was getting pretty snug. I love the material. It has breathable vents and itâs so easy to put on. He loves sleeping with it on and sleeps through the night with it, he is 4 months old. I wish it came in a bigger size because I would have ordered another one.
Indifferent about the whale tail
This swaddle is the perfect size for my massive 3 month old. The fabric is nice and comfortable and the mesh around the knees gives my baby enough space to frog his legs when he sleeps. The arms straps are really secure (the only swaddle he canât wiggle his arms out of) but the whale tail is more of a nuisance than anything. I understand it’s a safety measure if using leg risers but I never use it and haven’t had an issue with the sack riding up. It just gets stuck to the mesh inside and kind of in the way.Make sure to use the 10% off Amazon discount that you can get from the Snoo website! It’s the first pop up when you open the site.
I bought these to have an extra set of swaddles for the snoo! These are absolutely adorable and great quality. I originally bought these snoo in 2020 for my first child and these space themed swaddles seem to have been greatly improved from the original swaddles. The material is thicker, the velcro is stronger, and there is an extra swaddle strap that wraps from the bottom. 10/10 would recommend
Really helped my kid sleep. It’s soft and made of good quality. My baby runs hot and this sleep sack has nets on the top and middle so the baby doesn’t overheat.
Super easy to use, helps my baby sleep, super warm and cozy, looks cute!
Faulty Item, NO Snoo clips on the sleep sack despite these being Snoo specific sleep sacks. Happiest Baby sent us back to Amazon, and Amazon said this is beyond the return date despite that this is a baby item. Extremely unhappy with Happiest Baby and purchase.
It works but thereâs an extra lower Velcro strap that the original snoo swaddles donât have. It gets in the way if the baby is double swaddled or in a gown onesie.
