The Best Swaddling and Sleep Sacks


A swaddle is a great way to keep your baby safe, warm, and happy, with many parents reporting it helps newborns sleep better and fall asleep faster. There are many choices, ranging from newborn to toddler, for use in warm climates and cold winters.

We purchased the top 14 products available to find the best swaddling blankets, sleep sacks, and wraps. We tested each for comfort, ease of use, and durability or longevity. With hands-on experience and at-home testing, we can help you find the perfect swaddles for newborns or sleep sacks for older babies.

Our favorite sleep sack is the Woolino 4 Season Ultimate. This versatile sack is good for most seasons and sizes. It is naturally flame retardant and temperature regulating, thanks to the wool interior design.

Our favorite swaddle for newborns is the Miracle Blanket. This guided swaddle is easy to use and helps keep Houdini babies cozy and snug. It's also durable enough to be handed down for generations.

If you are looking for items to help soothe little ones, we've tested sound machines for babies for white noise and lullabies, night lights, and pacifiers for sleeping comfort. Looking to keep an eye (or ear) on what is happening in the nursery? We've also tested baby monitors.

Editor's Note: This review was updated on April 3, 2025, to add three new popular products from Happiest Baby, Ollie, and Copper Pearl.

The Woolino 4 Season Ultimate is a high-quality Merino wool wearable blanket with an organic cotton exterior. The wool is naturally flame-retardant and wicks moisture away to regulate your baby's temperature. The one-size sleep sack fits most children from 2 months to 2 years. Adjustable underarm snaps keep it snug around children of different sizes. Additional snaps on both shoulders and a 2-way zipper allow it to be opened and laid flat, making it easier to put on, even if your baby is sound asleep. During testing, one reviewer said, I appreciate the side zipper because it stays out of my baby's face and out of chewing range.” The Woolino also has a convenient slot for threading the crotch strap of a car seat or stroller, making it super easy to transfer a sleeping baby without waking them. Our tester reported, “I love this crotch strap opening; what a smart idea!

While advertised as a year-round product, some find the Woolino too warm to use during the summer months. The Burt's Bees Baby Beekeeper is a lighter-weight fabric and could be a better fit for warmer climates. Because Woolino is a one-size-fits-all product, many parents feel there is too much fabric for younger infants and prefer to use it once their baby is older. One tester stated, “I feel like it swallowed my small baby.” It's machine washable, but you must follow special washing instructions to keep the thin, delicate wool in good condition. Last, it is expensive, sporting one of the highest price tags in this review. However, thanks to its high quality and multi-age fit, you only have to purchase one or two until your baby is ready to sleep with ordinary blankets. We believe that most families will be happy investing in the Woolino 4 Season Ulitmate sleep sack.

The Miracle Blanket is an innovative take on the classic swaddle. We love that its lightweight, 100% cotton fabric resembles a traditional swaddle but is much more manageable. One tester said, “I think it is much easier to use this blanket than a traditional swaddle.” When swaddling the baby, a small flap tucks around each arm to keep them snug and prevent them from breaking out. From there, an extra-long fabric wraps around to keep it secure; no tucking or folding is required. At the bottom is a large pocket for the legs that won't come undone. If you think your baby will be too warm with the extra coverage, you can remove their legs from the pocket. To get the wrapping down just right, Miracle Baby offers helpful information on their website.

Like a traditional swaddle, diaper changes can be cumbersome. Our tester remarked, “I wish I could change a diaper without removing the entire blanket.” It's simpler than a conventional swaddle but more involved than zipper swaddles. The Ergobaby Swaddler allows for easier diaper changes without sacrificing a secure wrap. Due to the non-adjustable leg pocket at the bottom, extra-tall babies tend to outgrow the Miracle Blanket before the 14-week suggested age limit. Lastly, the arm flaps can end up under the baby's back, and all of the extra fabric can become lumpy under the baby's back. Some users find the material too light, but others like the flexibility to add layers rather than risk overheating with a heavier swaddle. Overall, we were impressed with the Miracle Blanket and would happily recommend it to anyone.

The Burt's Bees Baby Beekeeper is a lightweight, 100% organic cotton swaddle transition blanket available in various adorable patterns and is GOTS (Global Organic Textile Standard) certified. The zipper works in reverse and has a small pocket at the bottom to keep it tucked away and prevent it from catching on things. Our tester said, “I really appreciated that I could change diapers in the middle of the night without removing the sleep sack.” The fabric is very soft and machine washable. Plus, it's long, allowing for lots of extra legroom and making it a solid choice for tall babies or parents who want to get the most use out of baby clothes.

Unfortunately, the fabric is considerably thin and doesn't provide adequate warmth in colder environments. Our tester reported, “I can see how this might be too thin for colder climates or air-conditioned nurseries.” If temperature is a concern, consider the Burt's Bees warmer quilted option. This sleep sack also lacks convenient shoulder snaps, like those found on the Woolino 4 Season Ultimate, making it not quite as easy to put on. While the quality of the fabric is excellent, there are occasional complaints about loose threads and seams that come undone after a few washes. Because of the extra length, smaller babies may swim in the excess fabric, so be sure to take a look at the size guide to achieve a proper fit. Aside from this, we think that Burt's Bees makes an excellent organic sleep sack that will keep your baby happy.

The Ergobaby Swaddler is adorable, 100% cotton, and undeniably soft in our tests. The material has some stretch, making it suitable for babies who want some movement, and the neck hole is wider for babies who prefer that style. The manufacturer claims that this swaddle has an ergonomic design that keeps the baby's legs and hips in the proper ergonomic position, promoting healthy hip growth. The removable leg pouch makes diaper changes more accessible, and the swaddle's Velcro is quieter than some competing swaddles. Our tester stated, “I'm not a fan of Velcro and how loud it is in the quiet of the night, but this swaddle's Velcro isn't as loud as some others.

Although we appreciate the ease of a Velcro system, some users mention that this hook-and-loop system lacks strength, particularly over time. Our tester noted, “In my experience, Velcro is less effective over time after frequent washing or the hooks getting clogged with fibers.” Also, there's a learning curve when first swaddling your baby. This product even comes with an instruction manual. A more straightforward option is the Love to Dream Swaddle UP, but not all babies will find the arms up position comfortable. With practice, we think you'll be a master of the Ergobaby Swaddler in no time. It's a great contender if you seek an ergonomic design and handy leg pocket for diaper changes.

The Love to Dream Swaddle UP is an easy-to-use, zipper-style swaddle that makes middle-of-the-night diaper changes a breeze. Many families love how the two-way zipper lets you access the baby's diaper without completely removing the swaddle. Or, if the baby needs a change of clothes, it's super easy to unzip the swaddle and then zip it back on. During testing, one reviewer noted, “I love how easy this swaddle is to use - there are no bundles of fabric or loud velcro to contend with.” Additionally, the unique arms-up design is perfect for babies who find traditional arms-down swaddling uncomfortable and lets them access their hands for self-soothing. The cotton fabric is thin, stretchy, and breathable, offering gentle compression to soften startle reflexes.

The Love to Dream may not provide enough compression to soothe the youngest newborns, and some babies may not like the arms-up position or the zipper near their chin. If your newborn needs more soothing, the HALO SleepSack Swaddle is a great alternative. Additionally, some testers found the Love to Dream too snug — one said, “Sometimes I worry about the zipper catching on my baby's skin because of how tight the fit is. There's also not a lot of room for layering or a growing baby.” Love to Dream offers thicker fabric options for temperatures down to 61°F, but as your baby grows, you'll have to size up. Still, if ease of use is your top priority, most families will love the Swaddle UP.

The Aden + Anais Classic Swaddle is our favorite option for versatility. It is a roomy 47" x 47" soft blanket and comes in a large selection of cute prints and colors. The cotton muslin material is breathable but keeps your baby reasonably warm due to its multiple wrap layers. Many parents love how well it washes, noting that it doesn't hold stains from spit-up or other spills and messes. Our tester stated, “The muslin fabric gets softer after every wash.” Despite the delicate feeling of muslin, these swaddle blankets last. They can be used for a huge variety of purposes even after your baby has outgrown swaddling, including car seat/stroller cover, burp cloth, nursing cover, tummy time blanket, and changing table cover.

We love these blankets, but you have to trust your swaddling skills. You don't want the wrap to come loose, an issue that is not present when using zippered swaddles. Our tester stated, “I struggled to create a tight swaddle that stayed put all night.” The Copper Pearl Swaddle is a stretchier fabric that makes it easier to create a snug-fitting swaddle, but it still requires some practice to master. The Aden + Anais is pricey, but we think it's worth it, considering its longevity, versatility, and the fact that you get multiple (which lowers the cost per blanket considerably). We love the Aden + Anais Classic Swaddle and would recommend it to anyone looking for a general-use blanket in addition to a swaddle.

How We Tested


We researched more than 25 potential contenders before narrowing it down to the top 14 swaddles and sleep sacks in this review. We considered popular choices and those with highly regarded design choices, like organic fabrics. We tested each product side-by-side to determine the best option for each stage of life and lifestyle choice. We considered quality, design, comfort, and features. We also enlisted multiple children from 2 to 13 months to help us test our products for fit, comfort, and durability.

The sound of Velcro may not be something you've ever considered, but in the wee hours of the night, you’ll curse that loud rip as your baby starts to stir. Here, we compare the volume of the Ollie Swaddle (loud) and the Sleepea (quiet). Tip: Make sure the audio is unmuted.

Analysis and Test Results


Most babies love being swaddled. It can help newborns and infants fall asleep faster and help prevent the Moro reflex, which causes accidental waking at night. Sometimes, even after a baby outgrows the swaddling stage, they still enjoy being lightly cuddled by their sleepwear. Our review covers the details and differences between swaddles and sleepsacks and helps you decide when the right time to make the transition is. We can help you find the perfect swaddle for your infant or sleep sack for your growing toddler.


What's the Best Value?


Quality materials and construction can set products apart and enable them to endure years of use, possibly through multiple children. Swaddle products are only used during the first 2-3 months of a baby's life, so they are usually much less expensive. Our favorite swaddles, the Ergobaby Swaddler and Miracle Blanket, offer a good balance between price and quality.

Sleep sacks are products that your child may potentially use until their later toddler years. With that in mind, it's a good idea to invest in a sleep sack that will fit your baby for an extended period and is durable enough to last. With the Woolino 4 Season Baby, your child can use it from two months up to two years and during all seasons. The Burt's Bees Baby Beekeeper is one of the most affordable sleep sacks we tested but still maintains a quality feel; however, you will have to buy different sizes to use as your baby grows and varying weights to use during different seasons.

Wearable Blanket vs. Swaddle Blanket
Swaddles and sleep sacks can be an invaluable addition to your bedtime routine. Swaddles are best for newborns and younger infants and create a calming effect that mimics being in the womb. Non-traditional swaddle products have the comforting aspects of a swaddle but attempt to make it foolproof for parents to master with designs that are harder for babies to “escape.” Sleep sacks are for babies who've aged out of swaddles but still enjoy the comfort of being wrapped in a blanket like a loose burrito.

Baby Comfort


Your baby's comfort should be the first consideration when choosing a sleep sack or swaddle. You want your little one to be as cozy as possible so everyone can get a good night's sleep.


Since we can't ask our 2-month-old testers how comfortable they are in a swaddle, we rely on observations such as the softness and breathability of the fabric. We also ensure there is adequate room for the baby's hips and legs to move freely. The presence of zippers and Velcro are less significant, but if they are near the baby's face or bare skin at any point, we give it a lower score.

Velcro is great for creating a snug-fitted swaddle, but some Velcros, like that on the Happiest Baby Sleepea, are rough and can scratch a baby's gentle skin.

The highest score is earned by the Aden+Anais Classic Swaddle and Copper Pearl Swaddle. Both of these options are free of Velcro, zippers, and seams that may cause any discomfort. As a traditional swaddle, they are fully adjustable, so you can tailor the wrap to suit your baby's size. The Aden + Anais cotton muslin gets softer over time, while the Copper Pearl's polyester/spandex blend is buttery smooth out of the box.

The least comfortable product we encountered is the Summer Infant SwaddleMe Pod. It is a lightweight fabric that does not provide much warmth, and the shape is narrow from shoulders to toes, not allowing much room in the leg area. The 2-way zipper is excellent for parent convenience, but the baby will have a zipper pull tab in their face all night.

When to Stop Swaddling
Swaddling is good for babies up to about eight weeks old. When your baby starts showing signs of rolling over independently, the swaddle should be retired and replaced with a sleep sack.

Fabric/Materials


We think it is good practice to know what you're putting near your baby's skin, especially when it's something they'll be wearing for 8+ hours a day. Our favorite swaddles and sleep sacks are made of natural materials such as cotton or wool and get more points if they are organic, like the Burt's Bees, Love to Dream, Woolino, and Happiest Baby.

Most swaddles and sleep sacks come with a temperature guide and recommendations for dressing your baby. Typically, this information is on the company's website or provided in the product's instructions. How you dress your baby will depend on the garment's weight and the nursery temperature. You should always choose the swaddle or sleep sack that best fits your situation and nursery. Some parents tuck their baby inside the product with nothing but a diaper to make nighttime diaper changes more straightforward, while others prefer to have a onesie underneath.

The different materials of the swaddles and sleep sacks also provide varying levels of warmth, and most manufacturers give a TOG rating for their products. A TOG is a measurement commonly used in the textile industry to measure a product's warmth. Sleepsacks with a rating of 0.5 are relatively lightweight and best for babies who live in mild climates or sleep in warm nurseries. These include the Burt's Bees, Ergobaby, Summer Infant, and Happiest Baby. The highest recommended TOG for baby sleepwear is 4.0, but a maximum rating of 2.5 should be sufficient in most homes.

The Woolino 4 Season Baby is the only wearable blanket in this review with a wool lining. Wool is a breathable temperature-regulating fabric that helps keep the baby's body temperature stable and does not have a fixed TOG rating. This property makes it ideal for use in a variety of temperatures.

Ease of Use


Many of the swaddles and sleep sacks in this review are more manageable than a traditional swath of fabric where you fold or wrap the swaddle yourself. They achieve this by using zippers, snaps, and even Velcro in various combinations to create a wearable blanket that is easier to use and takes little practice to master.


The difference in ease of use between swaddles can vary significantly. Classic square swaddle blankets take the most time to master but can become useful later on for other purposes, especially if you choose a high-quality and durable product. However, when you first learn how to wrap your baby, it can be confusing and frustrating. For this reason, the Aden + Anais Classic Swaddle earned the lowest score for this metric.

The Miracle Blanket and Ergobaby Swaddler have arm pockets that take some getting used to, but the learning curve is short, and the benefit is a more secure swaddle for Houdini babies. Using a zipper/wrap combination such as the HALO SleepSack Swaddle and Sleepea is easier to use, but some users complain that the swaddle is easier to break out of. If you choose a zipper-only swaddle like the Love to Dream or Summer Infant, the process is even more straightforward, though you will have to purchase several sizes to keep up with your fast-growing baby.

Transitional
Hybrid styles combine the secure feeling of a swaddle with the convenience of a sleep sack. They can come in various styles, from suits to zippered swaddles, and are often helpful during the transition from arms-in to arms-out. Examples include the HALO SleepSack Swaddle, Baby Merlin's Magic Sleepsuit, Woombie Grow With Me Convertible Swaddle, and Happiest Baby Sleepea, and Ollie Swaddle.

All the wearable blankets in this review have a zipper closure. Most have a reverse zipper that starts at the top and ends at the bottom, but some have a 2-way zipper that allows you to unzip from either end. While it seems like a small detail, we think you will appreciate this feature when you can perform midnight diaper changes without undressing your baby.

The Woolino 4 Season Ultimate is one of the easiest sleep sacks to use. The zipper is located on the side, which keeps it away from the baby's face and stomach. Additionally, it has a snap system and a handful of other features, such as a seatbelt opening that allows for easy transfers between the stroller, car seat, and crib.

Shoulder snaps come in handy when trying to dress a sleeping baby without waking them. You can lay your baby flat on the garment and wrap, zip, and snap around them rather than trying to force their arms through tiny armholes. Armpit snaps also allow one-size sleep sacks to grow with the baby, keeping the armholes snug but not too snug as they grow.

Ease of Cleaning


If having a simple laundry routine is higher up on your checklist, you will want to pay close attention to washing instructions. These are usually material-dependent, but most sleep sacks will stay in better condition if you zip them and turn them inside out before washing. Most wool and some cotton sacks need to be washed on a delicate or cold cycle and air-dried to avoid shrinking. Suppose you want to throw the blanket in the wash with the rest of the clothes and not add special instructions to your list of a million other things to worry about. In that case, products like the Burt's Bees Baby Beekeeper or the Miracle Blanket are excellent choices.

Longevity/Durability


The amount of use your swaddle and sleep sack will receive can vary depending on your baby. If your baby is a light sleeper and will typically only stay asleep when following a strict routine, your swaddle will have to be able to withstand daily use and washings.


The Aden + Anais Classic Swaddle earned the highest score in this metric. It's high-quality, very durable, and can be used for a longer time. It also has more flexibility for uses outside of swaddling.

If you are looking for a product for occasional use, this metric may be less of a consideration for you. If you are in a pinch, Comfy Cubs Swaddle Blankets are the least durable, but they have a hard-to-beat price. The Summer Infant SwaddleMe Pod also didn't impress in this metric, but its price is compatible with the lower quality and might meet your needs depending on your goals.

Dressing for Sleep


Babies are not very good at regulating their temperature, especially in the first year of life. The ideal room temperature for a newborn is between 68° F and 72° F, and if you put a baby in multiple layers, they can be too warm. Most parents use sleep sacks and swaddles over clothing, and many come with instructions on how to dress a baby underneath, depending on the room temperature. A good rule of thumb is to add one more layer than you need to feel comfortable. Take care not to overdress the baby, though, as overheating can increase the risk of Sudden Infant Death Syndrome (SIDS).

How to Swaddle
You need to wrap the baby tight enough around the arms that the blanket won't come loose and become a safety hazard. At the same time, the fabric around the hips and legs needs to be flexible enough to give the joints the freedom to move naturally. Swaddling this way helps avoid hip dysplasia or instability or looseness of the hip joint.

Safe Sleep Practices


General safe sleep practices should be followed for every sleep.

  • Always put your baby on their back to sleep. Swaddling can help keep infants in this position and lessen the likelihood of accidentally rolling over early. The swaddle should be retired as soon as it shows signs of turning over. Once a baby can go from back to tummy and tummy to back, usually around one year, they can sleep in any position they choose.
  • Place baby on a firm mattress to sleep, free of loose blankets, pillows, bumpers, or toys to help reduce suffocation hazards. Nothing should be in the crib or bassinet with the baby, and you should never let the baby sleep on a couch, armchair, or sofa.
  • Room share, but do NOT bed share. Keeping your baby in the same room, on a separate sleep surface, for the first 6-12 months helps you maintain a close eye on your baby and can be more convenient.
  • Using a pacifier can help reduce the risk of SIDS, even if it falls out after the baby has fallen asleep.

These are just basic safe sleep guidelines. Many additional tips and more in-depth explanations are available on how to protect your infant from SIDS and other causes of sleep-related deaths.

Safety First
As always, safety comes first. In addition to finding the best product for your lifestyle, developing good habits and following safe sleep practices is crucial. The American Academy of Pediatrics (AAP) has updated its safe sleep guidelines with new recommendations, including the mention that weighted bedding, swaddles, sleepers, and other weighted products should not be used with babies. For more information, see their article, specifically Table 3, which compares the old vs. new recommendations. This is your best source of safe sleep information.

How to Pick the Best Swaddle for Newborns or Sleep Sacks


Finding the right swaddle or sleep sack can feel overwhelming when you aren't familiar with this kind of product. While you can swaddle your little one without considering all the options, products designed specifically for different situations, ages, and baby skill levels can make life easier. There are a few questions to ask before picking the best option, and the best option will change as your little one gets older or develops new skills.

What age is your baby?


Infants and young babies can be wrapped more securely in a swaddle, while bigger babies and those that can roll are better suited for a sleep sack where they have more mobility. As little one's age, their hip development can be affected by a tight swaddle, but newborns feel more secure when swaddled. This is why your journey starts with size, age, and ability. This helps cut the field in half. Do you need a swaddle or a sack?

Climate or Time of Year


Some of the products are for warmer climates, and some assume your home is a bit cooler. What option you choose should consider the climate of your baby's nursery and the time of year in your area. You don't want babies to be overheated or too cold, so you should choose based on temperature.

Special Features


Features like a reversible zipper or the ability to more securely tuck arms inside might be useful depending on your situation or your baby. If you have a Houdini of a child, then you might need an option that is harder to wiggle out of. If you want to simplify overnight changes, a zipper that pulls up from the bottom so changes can be made without removing the swaddle or sack can be super useful.

Conclusion


Keeping your baby warm and soothed during sleep time is the first priority, and swaddling is one sleeping solution. Swaddling can help calm your infant and prevent frequent waking, potentially increasing nighttime slumber. A wearable blanket for older babies helps keep loose blankets and pillows out of your baby's crib for longer to align with the recommended safe sleeping practices to help avoid SIDs. We did our homework on the products in this review and gathered the details you need to make the best decision for your baby and budget.
