HALO 100% Cotton SleepSack Swaddle Blanket, Print Boy, Small

HALO SleepSack Swaddle Keep your baby safe and warm with the HALO SleepSack Swaddle. Used in hospital nurseries throughout North America, this wearable blanket with swaddle wrap fits comfortably over your child’s sleepwear, replacing 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 2-in-1 adjustable swaddle that allows for swaddling arms in or arms out for baby’s comfort, which will ensure an easy and gentle transition to the SleepSack wearable blanket when it is time to stop swaddling. Its inverted zipper unzips from the bottom of the SleepSack, making diaper changes easy. 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. The HALO SleepSack Swaddle is the safe and easy way to swaddle your baby.

View larger Safe Swaddling, Made Easy After being tightly cuddled inside mom for nine months, it’s no wonder that some babies enjoy being swaddled after birth. It makes them feel snug, warm, and secure. Swaddling can help calm many fussy or crying babies and even help them sleep longer in the first few months of life. HALO makes swaddling safe and easy. Unlike a traditional swaddling blanket, which can easily become unwrapped, the HALO SleepSack Swaddle uses strong, adjustable fasteners to get the perfect, secure swaddle in just a few steps. Simply place your baby in the sack, close the zipper, and secure the wrap snugly around baby’s torso with the fastener strips. Recommended By Hospitals And Safety Organizations The HALO SleepSack Swaddle is used by more than 1,250 hospital nurseries in North America to teach parents safe sleep practices. The sack design allows room for your baby’s legs to move freely to ensure proper hip development, and has been approved as “Hip Healthy” by the International Hip Dysplasia Institute. It is the only wearable blanket to carry the gold seals from First Candle/SIDS Alliance and the Canadian Foundation for the Study of Infant Deaths. HALO’s Mission: Help Babies Sleep Safely HALO’s founder Bill Schmid and his wife lost their first born to SIDS. From this tragedy, HALO and its mission were born. For over 15 years we’ve been educating parents about safe sleep practices and have supported non-profit organizations such as First Candle/SIDS Alliance and The Canadian Foundation for the Study of Infant Deaths.

Today, HALO SleepSack wearable blankets are a trusted choice of hospitals, and are used throughout North America to help babies sleep safely from the start.

My favorite sleep sack for a large baby

It’s hard to find swaddle sacks in a larger size that do the job. My son was almost 12 pounds at a month old, and still needed to be swaddled, but had outgrown his newborn sacks. I use this one with the swaddle wings for another month, until he started working his hands out from underneath during the night. The great thing is that you can just fasten the wings underneath the baby’s arms after you no longer want to swaddle, and it just fits like a regular sleep sack, but with a little more "snuggle" around the middle. He’s now 14 pounds and still has room to grow in this one.

Too Large

I ordered the smallest size for my 2.5 month old and it was still too big to get a tight swaddle. He is even big for his age.The fabric is a nice soft fleece, comparable to most other fleece clothing sold for babies at major retailers. I can’t say how it wears over time since I returned this item.

My favorite way to swaddle

HALO swaddle is my favorite product to swaddle my babies, I know they will stay safely swaddled as they sleep. This elephant in neutral yellow is the first neutral print I actually like, great job!

Very light material and versatile

The SleepSack Swaddle Blanket is a light covering that keeps baby swaddled without overheating. The SleepSack is also versatile to where SleepSack can be partially unzipped to change diapers without necessarily unswaddling the baby. SleepSack can also be used when the child wants to have their arms/hands free by using the swaddling section below the arms instead of over the arms.

ok but velcro is very loud

worked ok at first but then my son learned how to wiggle out of it, which I guess meant it was time to not swaddle anymore. The velcro is a bit loud so when you do a middle of the night diaper change it startles and wakes the baby. No beuno. What is nice is that you have the option to make this into a sleep sack as well, but again, you still have to deal with loud velcro. Hasn’t quiet velco been invented??? Halo should really consider this option!

Love them!!! Tall baby issues though…

Love these!!! My baby won’t sleep in her crib without them. Much harder to "escape" from than the "Swaddle Me" brand- I’ve tried them all. Sack zips from the top down so baby isn’t bothered/scratched by the zipper and then you can then swaddle their arms. For very Houdini-ish babies you can leave their arms in the sack and then swaddle- very hard to get out of. These also help transition babies from needing a swaddle- you can leave one arm free for awhile to get them used to sleeping without it- without cutting them off cold turkey. My only complaint is that I’ve got a tall baby and she’s skinny so her legs aren’t going to fit, without being bent, in the sack much longer, but the bigger size might be too loose in the body…

Order the Small

The Halo SleepSack is awesome! Our daughter was sleeping 6-8 hours each night by the time she was 4 weeks old… I give the SleepSack most of the credit. We used is at part of our bedtime routine and it was like a signal to her that it was time to go to sleep. It also did wonders for nap times too. I was very disappointed when I discovered that you can’t swaddle once babies start to roll over (for safety reasons), but around 3-4 months she didn’t really want to be swaddled anymore anyway.I recommend that buyers get the small size instead of newborn (unless they’re REALLY tiny). The sack will be long, but the Velcro swaddle will fit even smaller babies. They grow out of the newborn size so quick. My daughter was too big for the newborn size at only 4 weeks, but wore the small size until 14 weeks when we started to wean her from being swaddled.

Love it, but prefer fleece version

These swaddle sacks are wonderful! My baby moves constantly and wakes himself if I don’t swaddle him for naps and bedtime. My little Houdini gets out of every blanket swaddle, no matter how tight or well tucked. This sack makes my life so much easier! My only complaint is that the cotton swaddle sacks stretch out and don’t hold him so well by the end of the day/next day. The fleece sack holds up much better.My son is almost 5 months and I’m still using these for at least another few months. I’d highly recommend owning a few.

Adorable- elephant print good for boys and girls

We have several Halo SleepSacks. They are great for keeping baby warm and cozy all night. The cotton ones are thick, but we are using the fleece ones for the winter. The elephant print is blue, but would be just fine for a girl too.

Terrible Velcro

I love the regular Halo SleepSacks but this swaddle version has velcro that is much too stiff. It pokes out the side and scratches my arms while I’m nursing my baby. At least it’s not a complete waste, I just cut the swaddle part off so I have a regular lightweight SleepSack. Would be nice if the swaddle part just snapped on so we could choose which way to use it.

HALO is the best sleepsack

HALO sleepsacks are the best! No other sleepsacks are made with the same quality. He stays warm and it stays put! So much safer than using a blanket which shouldn’t be done for children under 1 year old. The swaddle is great for when they are still young – swaddling is comforting. Then eventually, he learned how to get his arms out so we no longer use that, but he still wears it. We just fasten it under his arms.

Great swaddle sacks!

We love these. After I have my son velcro’d in, I tug the zipper down and don’t ever have to worry about it bunching around his face. Do secure the velcro before washing because it will snag e-v-e-r-y-t-h-i-n-g if you don’t! Cotton ones are great for warmer weather (or cooler weather with more clothes underneath) and still look great after many washes!

Hannah Weldon, CA

Great for everynight sleeping

Tried a few swaddles and this brand works great – it keeps our babies hands inside a lot better then most of the other swaddles we tried. He can still escape once in a while but overall holds him together well. The velcro is loud so if you need to change your baby or reswaddle them while they are sleeping it might wake or stir them. The small is pretty large so this wrap will last you a while – our baby is 4 months now and still uses it.

Sonia Mindoro, WI


I got this for my son when he started being too small for the other swaddles we were using. This is a LOT of fabric, and it was hard to get it tight around him at 4 mos and about 14 lbs. By the time he was big enough for the swaddling function to work, he was rolling over and I couldn’t swaddle anymore! The "wings" make it too much material to use easily as a sleep sac (wrapping with arms out doesn’t really work with it, too much fabric!). So, this would only really work well for a BIG baby who you can still swaddle with arms in.

Jenny Twin Falls, ID

Halo SleepSack great

This swaddler is really cute, not too thick so good for summer, and worked pretty well. Since it’s velcro it never closes that perfectly but works well. Love the fact you can put the flaps under the arms in the morning when it’s still cool but you want them free. The sleep sacks were cute but didn’t close properly so I liked this. Expensive though, can’t have too many of them.

Tanya Broadbent, OR

Sleeps in this every night

We’ve been using a SleepSack Swaddle since we got home from the hospital. Our little guy loves to be swaddled, and this couldn’t be easier. Plus, he can still kick his little legs to his heart’s content.

Teresa Lonedell, MO

SO good for 3+ months and the rollover issue!!

My baby girl is 3 months old and though she preferred a large swaddle blanket initially when we had to convert to arms out mode this has been a LIfesaver!!!! She is now sleeping soundly despite kicking fits at night.
