SAFE AND SECURE SLEEP SOLUTION: The Original Halo Sleepsack Swaddle replaces loose blankets in the crib, creating a safer sleep environment. Endorsed by hospitals nationwide to promote safe and restful sleep for your baby.
SOFT AND STRETCHY COTTON: Made from 100% cotton with a double-knit construction, offering a cozy and slightly stretchy feel perfect for swaddling. TOG Rating 1.5 (room temperature of 68°-72°F): Suitable for cooler evenings during spring or fall.
3-WAY ADJUSTABLE SWADDLE DESIGN: Generously sized fasteners allow a perfect, customizable fit. Adjust the swaddle for Arms-In to reduce startle reflex, One-Arm-Out hand to face for self-soothing, or Two-Arms-Out to transition to the Halo SleepSack, an easy transition when it’s time to stop swaddling.
CONVENIENT DIAPER DESIGN An inverted zipper opens from the bottom, allowing easy diaper changes without disturbing your baby’s swaddle. Sleeveless design minimizes overheating risk, while snug arm and neck openings ensure a secure fit.

Most important item in my newborns closet
My daughter literally wore this every night for the first 2 months of her life. It was a life saver! Her startle reflex was so strong she’s wake herself up waving her arms or legs and as we all know, newborn sleep is already slim so I take anything that affects my sleep seriously! This cozy swaddle kept her from flailing and make her feel all cozy so she slept well.This is a nice soft medium thickness cotton that is soft and warm but still breathable. I got the grey Ike but they have cute patterns too. They come in different sizes. Pay attention to the length as that matters since they’re totally zipped in. It’s super stretchy which makes it easy to swaddle up. I ended up getting a second one in case of overnight blowouts.If you have a newborn and you like sleep, you need this.

Great swaddle
Halo is great! Our daughter sleeps so well in them and I don’t have to worry about the fabric covering her face if she gets her hand out unlike normal swaddles.

Works but a little bulky for newborns
We like that this swaddle is versatile and we can use this with his arms in our out as he grows. It was a little bulky for our newborn and I preferred an easy zip up swaddle but as he gets bigger I think we’ll use it more. Soft material and no issues with the velcro after washing it.

Our baby sleeps so great, better than blanket swaddles!
My baby girl sleeps so good in this! We started using it from day one coming home from the hospital and she usually sleeps all night (10pm-5am). It’s been a lifesaver for these newborn days! She’s almost 3 months and we still use it everyday, even had to get a second one to have on hand just in case!

Best for first time parents!
We just had our 2nd kid and have previously had Halo sleep sacks with our first. Our kids both hated their swaddles and so this seemed to be the next best option. This one is worth the money since it is really soft and very easy to use! I would recommend this to any parent especially first time parents. The material is really soft and you can swaddle your baby 3 different ways with it. We typically use the arms out options since our kiddo likes to move around and typically gets her arms out of any swaddle anyways. Once again I would recommend and will keep buying Halo sleep sacks for the near future.

Great quality sleepsack
Cozy and warm sleeps acknowledged. Velcro works well. Fits perfectly, maybe even with some room to wiggle those little toesies.😋👣

Not great quality
Read all the reviews would be my suggestion! The Velcro destroys the fabric. We’ve been using this for one week and it’s already coming unraveled at the seams because it gets stuck to the Velcro.. I had higher expectations for Halo brand.
