The HALO SleepSackSwaddle replaces loose blankets in the crib that can cover your baby’s face and interfere with breathing. In addition to helping your baby sleep safer, it helps him sleep better, too. Its adjustable swaddle wrap immobilizes your baby’s arms to prevent the “Moro” or startle reflex. And, it is the only 3-way adjustable swaddle that adjusts to your baby’s sleep style. Swaddle arms in, hands-to-face for self-soothing, one or both arms out to ensure baby’s best sleep and an easy and gentle transition to the SleepSack wearable blanket when it is time to stop swaddling. Used in hospitals nationwide, the Halo SleepSack Swaddle is the #1 choice of hospitals and is recognized as “Hip Healthy” by the International Hip Dysplasia Institute. Its strong adjustable fasteners ensure a perfect fit and resist breakouts for more secure swaddling. Plus, its innovative zipper unzips from the bottom allowing your baby to stay swaddled for easy diaper changes. A portion of each SleepSack Swaddle you purchase will go to support non-profit organizations like First Candle/SIDS Alliance.
Made from 100% polyester microfleece fabric, the layers of sleepsack and swaddle provide a TOG rating of 3.0, ideal for chilly seasons and climates and keeping newborns warm and comfortable in any climate. Super-soft micro-fleece fabric is plush inside and out and is designed to wick away moisture. Size Newborn is designed to fit babies weighing between 6 and 12 pounds, who are generally 0 to 3 months old and 19 to 23 inches long. Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle wrap.

Great quality
The best sleep sack! This sleep sack has many different uses. I love that it and be used as a swaddle sack OR a normal sleep sack with babies arms out. Kept my baby warm and comfortable! Amazing quality, easy to use, and super easy to clean

Great For Baby
This sleepsack is very well made with adorable patterns and incredibly soft fabric. It keeps our baby warm and cozy, and the material is sturdy enough to gently hold his arms in place without waking him. Since we started using these, he’s been sleeping so much better and rarely wiggles his arms free. Highly recommend for better sleep and peace of mind!

Cutest softest swaddle
We absolutely love this HALO swaddle in the adorable Winnie the Pooh print! 🐻🍯 The fleece is incredibly soft and cozy—perfect for keeping baby warm during cooler nights. I love that it’s versatile—you can use it with arms in for a snug swaddle or arms out as a great transition sleep sack. It’s well-made, easy to zip, and washes beautifully. Our little one sleeps so soundly in it!

Great quality, fit and warmth
The velcro halo swaddles are the only ones I will use. They are so easy to put on, they stay in place and my baby seemed to like them the best. The quality is great, I used it for two babies and never had any issues with quality. The fleece is a nice weight because it keeps them warm and we can keep the house cooler for us (which post-partum is very nice to have a cooler house).

Infant sleep sack
This sleep sack was the only way I could get my baby to sleep for the first 6 months of her little life! The fabric kept her nice and warm in the northern utah winters and she slept so well! She would only wake once a night to eat and change her diaper. The zipper made it super simple to disturb her minimally to change. The fit was great and allowed us to use this longer term vs just a few weeks.

Favorite!
My baby loves these swaddles! It gets cold here but she is nice and warm in them. She’s 7 weeks and fits perfectly. There’s still plenty of room for her legs

Good overall
This was a great use in the first couple weeks and then I believe it shrunk. It also started to ride up on the mouth of the baby, but overall it kept baby asleep.

Great for newborn!
The hospital I delivered my baby in had these and she seemed to love them, so I ordered a few more. We have her sleep in one of these with a onesie underneath every night and it’s going great. She often manages to slip a hand out by her face, it’s so cute. This swaddle is very easy to use. Super soft, fits our girl nicely (she’s about 21 inches long now and close to 9 lbs), will continue to fit her for awhile for sure.

This product has been amazing in helping our baby boy sleep through the night.From birth he has always wanted the reassurance of feeling tightly held & was always swaddled in the ‘Summer infant swaddle wrap’ at night which he loved & slept through the night most nights from 7 weeks. So this sleep sack was ideal for when he outgrew the wrap as it had plenty of leg room for busy little legs & was really easy to wrap up his arms. On his first night of wearing it, he slept from 11pm – 6am Bliss!!As he’s now approaching 5 months we’ve slowly begun to wean him off swaddling both arms & have been able to do so one arm at a time with this sleep sack. After a couple of unsettled arm thrashes when initially put in his crib, he soon settled down as I think he liked the reassurance of the wrap around his tummy still. He now sleeps soundly with both arms out but if he gets startled in the night / unsettled with his arms, I can quickly wrap him up again if necessary.At nearly 5 months he is still in the 0-3 month size as he was only 5lb 3oz born so we’re definitely getting our money’s worth out of it. I’m just about to order the next size up though as he’s beginning to get a bit long for it. He has never managed to get his arms out / get it over his head like others have mentioned & is lovely & cosy with just this on over his babygro.As a first time mum, I would definitely recommend this product to other parents as we’ve found it a lifesaver for getting a full night’s sleep!! 🙂

C’était l’idée de ma femme d’acheter ce pyjamaJ’étais sceptique à l’idée de bloquer les bras de ma fille contre son corps et ainsi de l’empêcher de se mouvoir, mais c’est en utilisant ce pyjama qu’elle a véritablement commencée à faire ses nuits correctement.Ca a été efficace surtout parce que ma fille se griffait le visage en dormant et que ça la réveillait

I bought this for my newborn to wear in the house during the winter months and it fit him for about 2 months before it became too small for him. The penguin print is so cute and the fleece keeps him warm. The velcro holds up well against the late night twitches that normally wake the baby. I find it is so much easier to use than a swaddle especially when the baby is wriggling a lot. My baby likes to keep his arms out so I like that this sleep sack allows for him to do that or allows for him to be swaddled with his arms in. It’s easy to wash – just toss it in with all the other baby stuff on a gentle wash cycle and it comes out clean.
