Part of our nighttime routine

This sack is so cute! Every night we change our babies diaper, put the sack on, feed her and she falls right to sleep. She knows when we put it on it’s about that time. It’s actually great because it stops our daughter from poking her feet through her crib, which is why we got it.

Great sleep blanket for babies

After my son outgrew his swaddle, he still wouldn’t sleep well without some sort of blanket. Since actual blankets are not recommended, the halo sleepsack is the perfect item to use. It keeps him snug, cozy, and safe. It’s easy to get him in the sleep blanket (even if he’s already asleep) and the zipper zips down towards his feet so there’s no way he can scratch himself with it.I recommend this to anyone with babies.

Soft and warm, practical- lovely color

Our little one still needs a wearable blanket and we love the Halo Sleepsacks. This item is soft even after a few washings and the color is lovely!

Roslyn Rosine, KY


Our LO is 16 lbs and about 26 inches long, and this fits her very well. It seemed too big at first, but since she likes to kick, the size is perfect. Soft, comfy material, just right for fall before we switch to the fleece sleepsacks for winter. The zipper is at the bottom, so it won’t irritate her neck. It has never come close to slipping over her head, or even past her neck. Great price too!

Sherri Pulaski, MS


perfect pajamas for summer or winter. when its hot she wears just the sleepsack. when its cool she wears a onesie under.

Mandy Lewistown, MT

Cute and warm

With a friendly reminder that Back is Best. Also? He looks a little like a cartoon character when he’s in it. An adorable, adorable cartoon character.

For the Anti-Swaddler

From the moment my daughter was born, she didn’t want anything to do with being swaddled. She fought the nurses at the hospital and my husband and I once we got home. I was thankful being a new Mom I had Amazon Prime, I logged on and had two of these lovely little sacks shipped to my home within two days they arrived. My daughter loves them. She can sleep with her arms free and my husband and I know that she is safe in her sack so we don’t have to be worried about her possibly being suffocated by a blanket. I highly recommend this product for any infants who like my daughter are Anti-Swaddlers.

Dora Albany, CA

love it

got this cause I was not the best at swaddling and even with practice my little one kept squirming out, wanted to make sure she was warm at night, and this works great. easy access to the diaper, for quick changes when I need to.

HALO fan!

I like the Halo product. My 6month old is 17 lbs and 27 inches and decided he’s getting too big for the 0-6month Halo I had.It’s starting to get cold, but I’m sticking to all cotton. I’m too nervous about getting him too warm as it’s a risk for SIDS. The product is nice and thick compared to the 0-6month size and it’s generous. The arm & neck holes are big , this size is meant to last until 24lbs I believe so there’s plenty of room to grow. I prefer this product to the microfleece sacks you find at Target etc.. I don’t feel they breathe which again makes me nervous.I’m a Halo fan.

Betsy Hartland, WI

Perfect and provides peace of mind

This is the only way I feel comfortable bundling my little one. It is perfect for cool temperatures without having to break out heavy and hot sleepers.

Ollie Longmeadow, MA

A baby must!

A great baby blanket. Love the zipper–makes diaper changes quick without having to disturb baby too much. The cotton blanket works really well for nights that are warmer and you don’t want anything to heavy.

Esperanza Factoryville, PA

Good sack

This is a good sleepsack. Not too heavy, not too light. The Baby likes it for naps and at night.

Melanie Norris, SD

great blanket alternative!

have been using halo sleepsacks since my son got home from the hospital. they are a great alternative than leaving loose blankets in the crib and are easy to get him into or for diaper changes. will use until he is ready for normal blankets….

Petra Torrey, UT

Great – safe – alternative to blankets

I absolutely love these sleepsacks. I have purchased both the 100% cotton (for the warmer months) and the fleece type my little one. Both types are soft and wash up great. I line dry (rather than put them in the dryer) and they look new after numerous washes. They are easy to get the baby in and out of and even easier to access for a quick diaper change. A great way to keep your baby safely warm after he/she is out of the swaddle stage. This is such a great product; I plan on buying the footed version when my child starts walking. If you are on the fence about trying them… do not hesitate – go for it!

Jersey Cotton Sleep Sack

Great sleep sack for use in the summer – all cotton jersey material, very soft and very comfy for baby during those warm summer nights and cool summer mornings.

Polly Fairfax, VT

Good and not so good

I really love the Halo products, they are usually high quality and I feel my daughter is safe and sound using them. I love the extra long length of these sacks that leave room for stretching and kicking – my baby girl is training for River Dance so she needs the leg room. Also the cotton is very smooth and soft and high quality. Very pretty bubble gum pink and baby looks adorable sleeping in her crib in it.And, I think she just feels good in it! The night it arrived, we washed and used it immediately. She had been flailing around in her crib a bit (we stopped swaddling just a week ago) ,I put this thing on her and she laid perfectly still, head flat on the crib mattress, arms resting comfortably over her head lol. No stirring. She doesn’t usually look quite that comfy while sleeping.However, it has a really cheap zipper metal zipper that is difficult to zip. I fear that it will break, and it’s not coated in matching paint to make it a little softer, its just a hard silver metal zipper, and the catch is right under her chin 🙁 I have used other Halo sleep sacks that had the nice painted zippers that were very smooth and worked great. Not sure why they chose this zipper for this model.In terms of sizing, my baby has the size small and she is about 13 lb. She fits in it well but definitely has room to grow. I would expect this to fit her for at least several months. Most of these sacks go for around twenty dollars unless you catch a sale, so this was a good deal at around sixteen dollars.

Great Sleepsacks

We have tried multiple other sleep sacks and Halo has been the best. It is a great weight not too thick or thin and provides a good cover for babies. I like that her arms are free but it keeps her legs a contained a bit. By using this medium weight sleep sack we can put warmer or thinner pajamas underneath to control the warmth. The zipper is also great, I have used other brands where the zippers are plastic and cheap, they are harder to zip and sometimes get jammed, this has never happened with Halo.

Tia West Sayville, NY

Good product, but I like Summer Infant Sacks better

I have used the HALO sleepsacks and I have used the Summer Infant Swaddleme Sacks. I like the Summer Infant brand a lot better. They use a double zipper that makes it a lot easier to get on a squirmy baby. The price is similar, if not better, so get the Summer Infant ones instead. The patterns are cuter too! I recommend that you have at least 2 of these if you are going to use them every night.Summer Infant Swaddleme Sacks, Sweet Owls, Medium

love it

Beautiful bright pink color. Soft breathable cotton. Just enough warmth for baby. I love it! I bought two. I like these more than the fleece sleep sacks that seemed to bunch up by her face and were not soft after a couple washes.

Angelita Glenallen, MO

Halo sleepsack

As far as sleepsacks go, these are fine. Convenient, easy to zip up and down. Always make sure you choose the right material for whichever weather your baby will wear them for.

Noreen Copeville, TX

Easy and Comfortable!

My little guy loves his sleep sack(s)! He wore this cotton one throughout the summer, with just a long-sleeve shirt and diapers underneath. He looks adorable in it, too!

Janie Green Forest, AR

Great sleepsack!

Love this sleepsack! I’ve bought 4 of these so far (1 NB swaddle, 2 S, 1 M) and I’ll probably be getting more. I only gave 4 stars because the zipper could be a little easier to use, but otherwise this is a great product.I love how baby has lots of leg room and how the cotton has just the right weight.

Mari Pinon, NM

Amazing Product!!

These are the best gift I have ever received and I’ve purchased many of these on my own. I bought this pink one when my little one was an infant for the summer and it is the perfect weight. After she grew out of this small one we have kept purchasing these in the different weights, they have a fleece one for winter wear and the additional sizes. We only used them at night and it created a great routine and when the sleepsack when on she knew it was bedtime.Pros:- lightweight for the summer. Never had to worry about her getting overheated.- high quality, never had any issues with the zipper or the material- washes easily- zips from the top to bottom, easy to change a diaper in the middle of the night.- bright colors are easy to see if you are traveling. We had a white one and almost left it because it blended right in, with the pink you’ll never forget it.- A lot of space at the bottom for your little one to be in different positions. I love how they flare the bottom out so if your little one wants more space or to have froggy legs they have that option and are not uncomfortable.I love these, I’ve heard many people either love them or don’t have good luck with them. We were lucky that someone gave us our first one as a gift and I’ve since been purchasing more of these. We’ve had amazing results using these, and I don’t have to worry about blankets being kicked around and our little one getting cold in the middle of the night. It gave me a sound piece of mind and I would recommend them to anyone.

Reliable, comfortable, and held up through 3 kids

As a mom of three, I’ve tried so many kinds of swaddle blankets and sleep sacks, and always come back to Halo. They’re reliable, durable and you know what you’re getting. I use the cotton ones in the warmer weather and never have a problem with my children being too hot or uncomfortable. I throw them in the washing machine and dryer and the zippers and material have held up nicely, unlike other sleep sacks that I’ve purchased. My third child is using sleep sacks that her older brother and sister have used, so they wear very well. I highly recommend them to any friends who are having babies and often buy them as shower gifts.

Lula Grain Valley, MO

Great Sleep Sacks!

Our twins were previously wearing HALO size Newborn and have recently outgrown them. As the season has also changed, we felt the need to switch from fleece to cotton. We love these sleep sacks! Our girls weight approx. 14 lb each and are both about 24" long. These are roomy, comfortable, and lighter weight for the mild spring weather.

Marisa Williamstown, NY

Love this

Love this product. So soft and comfortable. Roomy enough for my 8 month old to sleep comfortably and safely! I would definitely recommend this sleep sack for cold nights.

Ida Annandale, MN

Can’t live with out them!

These things are awesome! Keep my baby warm but she can still move around and even stand up!! I lalready have the next size ready for her!

Mae Trinity Center, CA

Perfect lightweight sleep blanket for baby

It’s perfect for a lightweight blanket. Our house isn’t too cold, so I wanted something thin that would still cover our son. this is great!

Christine Falling Waters, WV

Good shape, don’t like the fabric as much

I have the Small Sleepsack in Turquoise Owl Print as well. This one is nice too, and the color is great. But it feels thicker / stiffer than the Owl Print for some reason. My little one can’t tell the difference and is just as happy in this one, but I deducted one star because I like the feel slightly less on this particular fabric.

Lesa Brielle, NJ

Great Product

This project is a good size for my 7 month old she will be able to fit in it for a while. It is sooooo soft and I love how the zipper zips down instead of up, so I don’t have to worry about her putting it in her mouth during the night. My baby girl seems to enjoy sleeping in these.
