First time mom- LOVE this swaddle!
As a first-time mom, the HALO SleepSack Swaddle quickly became one of my favorite newborn purchases. It felt noticeably higher quality than some of the other swaddles we tried and my baby seemed extra cozy and comfortable in it. I also noticed that my baby slept longer stretches in this swaddle than in some of our other options. The fabric is soft and the fit felt secure without being too restrictive. The sizing was true to the recommendations. Like most cotton baby items, it may shrink a little after washing and drying so some babies may need to size up slightly earlier than expected. One thing I really appreciated was how well it held up in the wash. Even with the Velcro going through the washer and dryer repeatedly, it continued to work well and maintained its quality. The swaddle includes a double zipper feature which many parents may love, but I personally didn't use it much. Overall this swaddle gave me peace of mind as a new parent and helped my baby stay comfortable and sleep well. I would definitely recommend it to other parents looking for a high-quality newborn swaddle!

Warm Swaddle
My baby loves the Halo sleep sack! This one keeps my baby nice and warm in 68 degree house. Fits her perfectly at 8 weeks old still has room to grow in it. Easy to use and nice and soft. Easier to use than other swaddles I have bought. Lightweight for the warmth

Cozy, convenient, WORKS
My baby loved to be swaddled but would always break his hands free. With a regular swaddle I was worried it would become loose and cover his face, this sleep sack made him sleep 4 hour stretches! 11/10, definitely worth the try. Worth every penny. Compared to other brands this feels durable but breathable.

Perfection!
These are absolutely perfect. I’ve tried a few other styles but they are either too difficult to put on a wiggly baby, or my baby escapes them within minutes. This style works great for me because my baby doesn’t like to have his arms constricted while I am trying to put him to sleep but I can wrap him up quickly once he’s asleep without moving him around too much in the process. My baby is one month and while it’s a bit large on him, I know he can use these for a while yet (these claim to be for 3-6 months). The Velcro is loud but I’ve not had issues with this too much because my baby isn’t bothered by loud noises (usually). I actually like the Velcro because my Houdini baby can’t escape as easily as he can in other swaddles. Highly recommend to any parent interested in a wearable swaddle. These beat any competitor by a long shot. They are pricey so I understand some people’s hesitation. I recommend at least two because my boy has peed through a diaper or two and I’ve only had one on hand and then struggled to get my baby to sleep well without it while washing. I now have three and am so happy.

Good product but size error?
I love that you can swaddle with arms in or out. Beware that it may not last as long as you think if you have a big baby. We got the small size when my baby was one month old because she is a 90th % baby. She now is 24”, 15lbs, just about to turn 3 months old and already doesn’t fit in it (her feet are tight at the end and stretch the swaddle). The swaddle says it is up to 26” but that certainly isn’t true for us. Also, the velcro is already starting to lose its shape so it fits weird around her. Even though she lost it faster than we expected, it saved us many nights and she seemed comfortable in it.

Ten Stars!
This sleep sack deserves ten stars for how easy it makes middle-of-the-night diaper changes. It is incredibly easy to use, keeping our baby feeling snug, secure, and comfortable all night long. The absolute best feature, though, is the inverted zipper that zips from the top down. When you need to do a diaper change at 3:00 AM, you don't have to unswaddle or fully undress them—you just unzip the bottom, swap the diaper, and you're done. It keeps the baby warm, quiet, and ready to drift right back to sleep. Highly recommend!

We love this swaddle
The nurses used one on our baby in nicu and it was nice because it kept him calm and helped him sleep despite the chaos a hospital setting brings. My baby screams every time I lay him down. Literally every time...I just got this in the mail, fed him, burped him, wrapped him in this, and hes currently sleeping in his crib (something he absolutely doesn't like to do). Im grateful for halo. It has helped us. My baby is 4 weeks old.

Soft and comfortable
This sleepsack is soft, lightweight, and feels comfortable against my baby’s skin. I like having a wearable option instead of loose blankets in the bassinet. The cotton material is breathable and the zipper makes diaper changes much easier than dealing with a traditional swaddle. It has held up well after use and washing. Definitely a convenient addition to our baby’s bedtime routine.

Too big
The band was too big compared to other Halo 3-6 month swaddles. Could barely get it to Velcro because it was so big. Soft, stretchy, and great quality.

Perfect for Newborns
My baby started kicking away flannel swaddles a week into his birth. It was impossible to keep one on. And given that they like their arms and body all wrapped up to feel secure, we needed something that could stay put. Halo swaddles are a perfect solution. 1.5 tog is perfect for Canadian households in winter time. They are soft, pure cotton, easy to put on and off the baby, machine washable.. just everything you need those first few weeks to get you baby and yourself some sleep. Love it.

Muy bueno
Un gran producto, la tela ni muy gruesa ni muy delgada, perfecta para la primavera y para los días de invierno. El diseño muy muy lindo y no se ensucia tan fácilmente. El único detalle es que viene más reducido de los pies que los demás sacos de la misma talla y marca.
