Description

The HALO Sleep Sack Swaddle 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, one or both arms out to ensure baby's best sleep and an easy and gentle transition to the Sleep Sack wearable blanket when it is time to stop swaddling. Used in hospitals nationwide, the Halo Sleep Sack 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. HALO also proudly supports non-profit organizations like First Candle/SIDS Alliance. Use over regular sleepwear to take the place of loose blankets. Discontinue swaddling when the baby shows signs of rolling over or breaking out of the swaddle wrap. 100% cotton interlock.

    • Soft, and Breathable
Color: Jungle Size: Small (Pack of 1)
This is a great swaddle. Easy to use and no complicated folds. 100% cotton so it is breathable and not too hot but keeps baby warm and secure feeling. I think every grandparent or parent who wants to be able swaddle quickly and securely should purchase one.

Color: Blue Safari Size: Newborn (Pack of 1)
Our newborn hates to sleep with her arms swaddled, we have tried so many different swaddles and the Halo swaddle is the only one she seems to like, while keeping us confident that she’s warm and secure.

Color: Blue Safari Size: Newborn (Pack of 1)
The HALO 100% Cotton Sleepsack Swaddle has been a lifesaver for our family. It’s truly the only swaddle my 1-week-old grandson loves. He settles quickly, sleeps more soundly, and seems so comfortable in it. The fabric is soft and breathable, and it’s easy to use—highly recommend for newborns!

Color: Baby Blue Size: Newborn (Pack of 1)
These are amazing. Our baby busts easily out of a muslin blanket swaddle, but the velcro stays put! He can sometimes get his hands up but it still prevents the jerking awake which is the whole point. Strongly recommend. Also note that if you go to the halo website, they have charts of how to dress your baby underneath the sleepsack according to your house temperature, which I found hugely helpful. Be aware when washing these in a machine to attach the velcro and put it in a mesh bag, otherwise it can catch other clothes - the velcro is quite strong. ... show more

    • Our Go To
Color: Heather Gray Size: Small (Pack of 1)
These sleep sacks have ended up being a newborn staple for us. We had a lot of trouble finding 1.5 tog sleep sacks that were made for newborns. They are easy to put on, wash and dry nicely, and keep our baby a comfortable temperature. The fabric is medium thickness, and feels high quality. A few things to note: 1. Sizing- the newborn size fit our baby well until about 11lbs 22inches. This was at about 8 weeks old. We upgraded to the 0-6mo size and they fit very nicely. 2. Versatility - our baby hated being swaddled, but the wrap portion secured easily under his arms. The fabric isn’t totally smooth under his back when used this way, but it doesn’t seem to bother him. 3. Zippers - this is the only reason I subtracted a star. The zippers work just fine, but there is no way to know if you’re getting a single zipper that completely disconnects, or the double zipper where you don’t ever have to disconnect and reconnect it. We even got the same pattern in a size up and got a different zipper. I much prefer the double zipper, because lining it up in the dark is a challenge. 4. Warmth - we found the 1.5 tog (68-72F) to be accurate. We sleep with a fan, room temp 68F, and baby just needs a footie pajama and the sleep sack to stay comfortably warm. 5. Washing - just a note, I connect the Velcro tabs behind the sleep sack for washing. This keeps your other clothing from sticking to the Velcro, and allows it to dry without leaving a wet spot from too many layers of fabric. Edit: I would not purchase the safari print in the 6 months size again. The fabric is too rigid, and I can see the arm holes becoming too small soon. The grey fabric is excellent, stretchy, and soft. ... show more

A favorite for our baby. These grow with baby as they reach milestones like rolling. Wish they made them in bamboo but still great.

This worked great until my baby didn’t like being swaddled any more and needed to transition to a different TOG.
