SleepSack Swaddle
100% cotton premium fabric with no added chemicals. Now with two-way zipper and zipper covers at top and bottom.
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 SleepSack wearable blanket when it is time to stop swaddling.
#1 Choice of hospitals. Used by hospitals nationwide as their swaddle of choice for safe sleep education. “Back is Best” embroidery reminds caregivers to place baby on his or her back.
Generous sack design allows room for kicking, but cannot be kicked off so baby stays warm all night. Recognized as “Hip Healthy” by the International Hip Dysplasia Institute.
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.

Fantastic swaddle
We love this swaddle for our little one. As long as it is not too warm for the environment in which they are sleeping, it is the perfect winter swaddle for a winter baby! It is soft and washes well. The Velcro is tough and manages to keep my 3 month old from escaping the swaddle, which no other swaddle seems to be able to do. It is loose on the hips, so no problem if hip dysplasia issues and it has good length for their legs. You can also use it with the arms out, just to give them a close hug with the swaddle, providing comfort while allowing their arms to be out when they can roll over. We love this swaddle and would recommend it. We did not like the same swaddle by Halo in cotton, as it was so stretchy that our baby could get his arms out every single time, then startling himself and waking himself up. Itâs the fleece material that is the best, again if not too warm for your sleeping environment.
Loved these for our baby!
I love the Halo swaddle for putting our newborn to sleep. It is quite soft and secure, but does stretch out over time using it. It still is great and attaches to secure a baby in it, you just have to roll them over quite a bit more to attach it underneath. I swear by these to help stop the startle reflex and help a baby sleep longer in the night!
Love it! Wish I had bought it sooner.
I ordered this sleep sac to help my 3 month old baby transition out of swaddling. While we haven’t transitioned yet, I wanted to write a review to let other parents know how great this product is. I am really impressed with the quality – the zippers and material are really good. The material is super soft and light, but keeps bubs warm. I think it is a great investment as it can double as both a swaddle and then eventually just use as a regular sleep sac. I wish I had purchased one sooner when my baby was a newborn (this would have been way easier to use than swaddle blankets or other Velcro products). The Velcro is REALLY good – very thin but holds well and yet easy enough to un-do without ripping/pulling the fabric. If we end up having baby #2, I will DEFINITELY be ordering a newborn size to start off with a Halo swaddle from the get-go rather than struggling with less superior products (or blankets).
It’s a great sleep sack!
Great sleepsack and let me keep my house cold, while my baby was nice and snug and warm. But overtime, with washing, the velcro parts kind of warp and become less comfortable. I also find because the flaps on either side attach at the back of the sack, that as your baby grows bigger, it isn’t comfortable for them to have something bunched up on the back quite like that. I switched to a sack that doesn’t have these flaps. Otherwise, it’s great!
Our most favorite sleep sack
We love this sleep sack swaddle! We had two of these already and bought another! Itâs perfect for a baby that needs to be swaddled and has a strong Moro reflex. This swaddle helps our son sleep so much better! I prefer the cotton over the fleece to avoid overheating if co-sleeping! Great buy!
Amazinggg
Iâve used halo sleep sack for both kids now and Iâm in love !! I always buy them for new moms as well. Gives me so much peace of mind when it comes to safe sleep, and is very easy to use!
Swaddle with style!
Our newborn loves to keep one or two hands out of swaddle to do wonders. This product was exactly what we were looking for!You have an option to keep both hands inside / one hand out / two hands out. Keep your babyâs hands locked in or loose to fall asleep faster. The material is nice and soft too.Itâs also easy to change the diaper by unzipping the bottom part of the swaddle.Be aware and latch your swaddle for machine wash. We had a fun ball of clothes as we havenât thought of it during the first wash.
Perfect for warm nights with a newborn!
My baby loves this swaddle! We were looking for something cooler for babe to sleep in on those summer nights and this was perfect. Couldnât be happier.
These sleep sacks were a godsend in the middle of the night for changings and easy to swaddle while keeping her feet free. Inclusive sizing for preemies was a massive plus, and we used different sizes of ours from preemie to 9-12 months (I forget now). Also love the different TOG ratings.
I love the halo swaddles for transitioning, they are just thick enough that she stays warm but not to bulky. Nice material and easy to wash!
Our daughter wanted her arms above her head during sleep and we were trying to find a solution to this. This has been absolutely wonderful to keep her flat on her back and also still pseudo swaddled. I will say our daughter weighs less than 7 lbs and the swaddle is alllllmost not small enough for her but still works great. Maybe we will get more used to it and get it tighter, regardless sheâs going to grow so it wonât be a problem for long. The material is really light so I would recommend a sleeper underneath and you should be all good! Buy it!
Great sleep sack, cute design. Some of these have a zipper that can open from the top or the bottom, while this one just opens from the top.
Best baby swaddle! I love being able to transition into arms out. Plus, the pattern is the sweetest!
