Sleep sacks, also known as wearable blankets, are an excellent example of a product designed with your baby’s benefit in mind. These veritable lifesavers ensure that your little one will not kick their blanket off during the night nor get wound up in the fabric as they wiggle around in bed, trying to get comfortable. 

These wearable blankets vary in material type and thickness, we suggest thinking ahead and getting a couple for the different seasons like a thick one for the winter and a lighter one for the summer months.

Just don’t forget to factor in how much your child will grow until the other season rolls around! Now, without further ado, check out the list of best sleep aids you can get for your baby – sleep sacks.

Find the Right Sleep Bags for Baby and Toddler

Halo SleepSack Swaddle

We begin the list with a beautiful product from HALO that has been designed to offer a great deal of comfort, and many parents’ reviews seem to attest to the fact that the SleepSack Swaddle is a fantastic product for newborns. It’s made of 100% high-quality cotton, and it will immobilize your baby’s arms, thus preventing the startle reflex from waking them up. The material is comfortable and soft, making this product an excellent choice for your baby.

The swaddle is suitable for all seasons but probably works best during colder nights, due to its strong warming factor. You can adjust the swaddle in three different ways, giving you some variety.


  • 100% cotton
  • Safe, comfortable and warm

Nested Bean Zen Sack Classic

This cozy and adorable sleep sack should have your baby sleeping in comfort. The weighted bean on the front is not too heavy, but just enough to keep your baby calm and relaxed. What we love most about it is how easy it is to get your baby out with the quick shoulder snaps, as well as the two height settings. The bottom has double zippers, as well.

A diaper change is easy thanks to this combination, which allows the sack to be opened up completely, without even waking your baby if you’re extra careful. The material feels very high-quality, and the fabric is quite soft. If you’re still on the fence, read some reviews from other parents, who say that their babies were sleeping better after they got this.


  • Double zipper
  • Adjustable shoulder snaps
  • Soft cotton

Love to Dream Swaddle UP

Many parents call the next product on our list a real gamechanger. While most swaddles keep babies’ arms down, this zip-up swaddle lets you sleep with your baby’s arms up – thus the name. It’s an excellent choice for parents who don’t like the complexity of a regular swaddle, as well as those babies who want to ‘raise the roof’ but still need their swaddle reflex calmed. 

The main advantage of this swaddle is just how quickly you can get your baby swaddled up compared to other sleep sacks on the market, which mainly comes in handy on those extra fussy days or nights. The zipper design is what makes this quick work possible since no spare time is spent folding and trying to hold down your squirmy arms of your baby girl or boy.


  • Super quick and easy to use
  • Lets your baby sleep in their natural position
  • Machine wash

Carter's Baby 2-Pack Cotton Sleepbag

Another high-quality option that you can wrap your baby into without worry is this Cotton Sleepbag from Carter. The premium quality, soft cotton will make your little one feel cozy and relaxed, and the bag itself has a soothing effect on a sleepy baby.

If you want your baby to sleep longer and go to sleep faster, this is a great choice. For extra options, the bags come in a two-pack, where one is 100% polyester, while the other one is 100% cotton. When the weather is cold, you can opt for the heavy cloth, while on warmer nights, the polyester sack will do wonders. The medium-sized Sleepbag is intended for infants aged six to nine months, while the small size is suitable for newborns.


  • Machine wash

  • Two-pack

Carter's Baby 2-Pack Microfleece

One more two-pack from Carter’s finds itself on our list. These cute little sleep bags are going to be sending your little one to Dreamland in no time and keeping them there throughout the night. The bags feature neutral pastel tones and a variety of colors and patterns, like bunnies, hearts, and clouds. Your baby will look cute in these, and most importantly, they will be comfortable.

These microfleece wearable blankets are perfect for chilly winter nights because they have long sleeves, while most sleep sacks of this type are sleeveless. The fabric is not too heavy, though, so don’t worry about overheating and sweating. You can cover the zipper on top with a neat tab to keep comfort at a maximum level.


  • Great for winter nights
  • Long sleeves


This gorgeous two-pack is another one on our list that will get your baby cozy and relaxed. The pack includes two white sleep sacks, one with a cute butterfly print in black and pink, and the other one that features the words ‘Mommy’s sweetheart’ on an embroidered patch on a polka-dot background.

The material is very comfortable and soft and has the right thickness to keep your baby warm while preventing overheating. These wearable blankets don’t feature a zipper, but the snap closures are high-quality and make it easy to get your baby in and out of the sack quickly when they need a diaper change in the middle of the night.


  • 100% cotton
  • Two-pack
  • Machine wash

The TOG of 0.5 means that this sleepsack is intended primarily for the summer months or for well-heated rooms, but due to its lightweight design, it can be easily layered for those colder nights as well. Despite its lightness, the HALO Sleepsack is quite roomy, allowing for healthy hip growth, which is why the  International Hip Dysplasia Institute recognizes the product as hip-healthy.


  • Hip-healthy

HALO Big Kids Sleepsack

As mentioned earlier, HALO SleepSacks have been the norm in nurseries and hospitals nationwide for years, and parents seem to have caught on as well, so products from this manufacturer are getting more and more popular by the minute. The HALO Safer Way to Sleep Initiative saw 1,000 nurseries get a SleepSack Swaddle to replace blankets, which is a feat worth noting.

As your child grows, HALO still has products to offer, such as this Big Kids Sleepsack – a new lightweight design that provides your child the security and warmth of a SleepSack so they can sleep soundly and fall asleep fast while not compromising their mobility when awake.  Teach SleepSack has a cute design and a zipper that zips ‘backward’ from the bottom up.

The SwaddleMe is made of 100% cotton muslin and comes in a small size meant for newborns (0 – 3 months) as well as a larger size intended for baby boys and girls three to six months old. The secure design creates a feeling of comfort and safety and prevents the startle reflex from waking your newborn.

Hudson Baby Unisex

If you’re not a fan of large sleep sacks and prefer the more light design for the summer months, this could be the choice for you, especially if you prefer cotton over fleece. The Unisex sleep bag from Hudson baby has a cute pattern, and the zipper flap prevents it from flapping up and irritating your little one’s skin. The size chart works well, according to parents’ reviews, so you shouldn’t expect any unpleasant surprises in that regard. 

We’d recommend getting a larger one so it could last a long time as your child grows, just roll the sleeves up in the beginning. If you want to have quick access to diapers in the middle of the night, this is the best way to go.


  • Closed bottom
  • Built-in mittens
  • Super soft

You’ll realize that this is a sack made for winter from the looks alone, with the fluffy, furry outer layer, but the blanket is also quilted on the inside and fitted with polyester, so it’s well insulated.

This product was created for parents whose children have trouble sleeping unless they are cocooned and nested. The zipper is top to bottom, making changes simple while keeping the zipper out of your baby’s face.

  • Shoulder straps
  • Cozy and safe

How to Choose a Good Sleep Sack?

If you want to maintain your peace of mind while still being sure that your baby is sleeping safely, get a sleep sack. It is a great way to make sure your baby stays warm during the night and avoid the increased risk of SIDS that is often associated with comforters, blankets and other items in your baby’s sleeping area.

So now that you’ve decided that you want a sleep sack and know why you need one, there’s only the tiny matter of picking the best one from a wide variety of options. Just like with any baby product, there’s a lot of research you need to put in before you can make a confident decision since there are so many sleep sacks on the market nowadays that picking the right one for your baby’s needs is going to be quite tricky.

The most important thing you should keep in mind when looking for a wearable blanket or a sleep sack is that it fits properly. The bag should be long enough not to constrain your little one too much, but you also don’t want to give them the option of wiggling down into the bag as that could be quite dangerous.

The fabric, particularly the weight of it, matters as well. It’s critical to keep your baby from overheating during the night since that is also considered to be a risk factor.

Criteria We Used


As mentioned earlier and many times before in our lists, reviews, and blog posts, safety is our number one priority. Since overheating is a common cause of Sudden Infant Death Syndrome, we made sure to provide you with a wide variety of TOG, or Thermal Overall Grade, ratings on this list. Remember that if your baby is wearing a sleep sack, they shouldn’t have another loose blanket in their crib.


Each of the products on our list is made of a safe, durable, comfortable, and soft fabric that will keep your child cozy and warm. Whether it is wool, polyester, or cotton muslin, we’ve made sure to select only the best, safest, and most comfortable materials that will allow your little one to enjoy their slumber sessions.


Now that safety and comfort are taken care of, we can talk about how cute your baby will look in these sleep sacks. Seeing as this is an item of clothing that your baby will probably be using most often in the first few months of their life, we took this criterion seriously and made sure to pick the most stylish and cutest items on the market.


What should my child be wearing underneath the wearable blanket?

The main factor this depends on is obviously the temperature of the environment your baby will be sleeping in. Most of the time, they should be fine in a cotton onesie, a long-sleeved one if their sleep sack is sleeveless. This could differ depending on your surroundings and climate, so use your better judgment. If you live in a colder climate, your kid might need to wear more layers, or if your nursery is particularly well-heated, you might want to consider different options. As a rule of thumb, if you feel like you would be uncomfortable wearing a certain number of layers, so would your baby.

What does TOG stand for?

This acronym refers to a unit of measurement for thermal resistance or temperature control known as the ‘Thermal Overall Grade.’ In the textile industry, this measurement is used to calculate thermal insulation. Sleep sacks with a TOG rating of 1 or lower, are intended for rooms with a temperature between 75 and 81 degrees Fahrenheit. The colder the room, the higher the TOG rating should be.


In our collective opinion here at Funtastic Toy, these are the best sleep sacks on the market today, and each and every one of them should be able to give your child a comfortable and safe night. These wearable blankets are tested for safety, highly rated by other parents, and recommended for use by childcare specialists. 

If you want your baby to sleep longer and go to sleep quicker, they are great choices. Now it’s up to you to consider all the variables and make your choice of which comfy baby sleep sack you want to put your child into.
