14 Best Sleep Sacks of 2024 to Keep Your Baby’s Crib Blanket-Free

Halo is the brand that coined the term "sleepsack" and it's a favorite among parents and our experts. The wearable blanket is roomy, not confining. Its zipper sits at the bottom instead of the top so you don't have to worry about it scratching your baby's face, and it makes overnight diaper changes nice and simple.

We like the style shown — a cotton knit fabric that our Textiles Lab confirms feels super soft and gives warmth without trapping in too much heat. Halo also has a microfleece version for colder weather and a breathable muslin variation for warmer temperatures.

Most wearable blankets are sleeveless, but this microfleece style has long sleeves for extra warmth on chilly nights. The fabric feels soft and cozy, but our textile experts say that it's not too heavy for those worried about overheating. "My kids particularly liked that the arms felt extra snug and cozy, because we kept their rooms cool," says our Chief Technologist & Executive Technical Director Rachel Rothman. "I was always so sad when they outgrew these!"

These sleep sacks have a tab to cover the zipper at the top and protect your baby's chin. The zipper can be used from the top or zipped up from the bottom. If you know you'll be buying multiple sleep sacks, this set of two is a total steal at less than $10 per sleep sack. It also has earned over 8,000 five-star reviews on Amazon.

Burt's Bees Baby makes a sleep sack with GOTS-certified organic cotton so you know the entire manufacturing process (not just the growing of the cotton) follows strict standards. Our Lab experts say it's also soft thanks to a special production process that removes short fibers and only leaves the long, smooth ones.

It zips from the bottom up for easy diaper changes and has a tab cover at the bottom to prevent your toddler from trying to unzip it themself. We're fans of the hand-drawn prints that make these sleep sacks look high-end for their affordable price. If you're a fan of the look you can go all-out. "I coordinated one of these sacks with other items in the nursery including the Burts Bees Baby crib sheets," Rothman says.

If you want to start early with a wearable blanket and not worry about making the transition from a swaddle to a sleep sack, this one is designed for infants. It has a zipper just like a regular sleep sack, but it has a more snug fit and the arms are still slightly restricted to help prevent a newborn's startle reflex. You can choose whether to leave baby's hands covered or uncovered with the clever foldover mitten cuffs.

The closure down the front is a two-way zipper that can zip from the top or bottom for dressings and diaper changes.

Have fun where you can when parenting a baby! Sleepy Bags from Little Sleepies have themes from Harry Potter, Star Wars and Disney. Pictured is Jack from The Nightmare Before Christmas, but there are also many Disney princess Sleepy Bags and characters from the Toy Story movies, too. You can also buy them in solids and pretty patterns. They're fun for snapping pictures while also being very practical wearable blankets.

A double zipper runs along the bottom of each sack for easy diaper changes, and the shoulder straps snap up for dressing and undressing. In addition to coming in multiple sizes, you can choose the weight of each Sleepy Bag; they're available in lightweight, season-less (middleweight) or winter-weight fabric.

Parents get a little obsessed about the zippers on a sleep sack. Trying to move a bad zipper that catches can wake the baby or make diaper changes more of a hassle. A smooth, two-way zipper that goes both up the sack and along the bottom seems to solve a lot of problems and has many parents gravitating to this HonestBaby wearable blanket.

You can unzip just the bottom of the sack to change your baby's diaper at night without them getting chilly. Because the zipper also goes up the side it's easy to put on at bedtime. Fans also praise the durable, soft fabric and our experts appreciate that it is made with GOTS-certified organic cotton.

Because it's made from organic cotton and merino wool, a soft and temperature-regulating fiber that can be used all year long, this sleep bag is a little pricey. But it's adjustable in size, so you won't need to buy a bigger one as your baby grows. You simply change which snaps you secure under your baby's arms to change the fit of the sleep sack.

There's a two-way zipper on the side and the shoulder straps also just snap together. This one also includes a seatbelt slot so your baby can wear it while strapped into a bouncer seat, swing, stroller or car seat.

This super plush chenille fabric feels like a cozy throw blanket. In fact, it's so soft you'll wish they made it in your size! (The California-based brand does make deliciously silky kid blankets for the preschool years.) The zipper sits at the bottom and it has a snap-button tab at the top to protect your baby's chin from the zipper.

This one is sized for newborns and infants and comes in a gift box, so it would make a perfect baby shower gift. We like that it is both machine-wash and tumble-dry ready so it's easy to care for.

Aden + Anais is best known for its cotton muslin baby blankets that serve as great swaddles, stroller blankets and nursing covers. The brand uses the same popular fabric in its wearable blankets. Our textiles experts note that cotton muslin is breathable so it helps prevent overheating, especially nice in the summertime or if your baby's nursery runs warm. Our Lab experts and consumer testers also confirm that the fabric keeps getting softer over time as you wash it.

Like some others, this style unzips up the front starting from the bottom for easy diaper changes. Cute new design patterns come in all the time.

Parents of winter babies and families who live in colder climates often search for wearable blankets with sleeves. This budget-friendly set of two only comes in one size, for babies from birth to 9 months, and online reviewers caution that big babies might grow out of one by about 6 months. But for infants, it's "super cozy and comfortable" according to one reviewer who put her daughter in a Hudson Baby sleeping bag when swaddling was over.

The zipper zips up from the bottom of these sacks. Many of the brand's prints are seasonal and wintery.

A rayon-and-spandex blend makes these sleeping bags silky soft and also lightweight, so many parents like them for babies who seem to run hot at night or for nurseries that are always on the warmer side.

"Smoother fabrics, in general, are less likely to be itchy, which is good for sensitive skin," adds our textiles expert. But be wary of claims from this brand and others that tout their fabric as coming from bamboo; in the end, the fabric is still just rayon. See our PSA: There's no bamboo in your bamboo bedding.

We have lauded Hanna Andersson for having the most popular baby clothes, and this classic wearable blanket from the beloved brand is soft and puffy like a traditional sleeping bag. Like the brand's pajamas, the wearable blanket is durable and we find it holds up to machine-washing over and over.

The zipper zips up from the bottom for easy diapering. The manufacturer suggests a baby wear minimal pajamas under this and sleep in a nursery set between 60 and 70 degrees to prevent overheating.

The appeal of the Zipadee-Zip is that your baby's little hands stay covered — good if your baby accidentally scratches their own face with their tiny nails. Many parents also feel this makes a nice transition from a swaddle. You may have seen the brand snag a deal on Shark Tank to launch the design!

Our analysts had mixed feelings about the arms being covered because it's critical that a baby be able to push themself up if they roll over in the crib. However, online reviewers report that their babies can push up, hold onto the crib railings and even stand in this full-coverage wearable blanket. For extra safety, you should wait until your baby has strong head and neck control before using this so that if they do roll over, they can turn their head for easy breathing.

If you're still not ready to use a regular blanket when your baby becomes a toddler or you just want to make sure they'll stay warm without the covers falling off, a wearable blanket with legs is the perfect solution. It zips on just like a regular sleep sack and can go over light pajamas, but it gives your kid the freedom to walk around.

Halo makes this sleep suit as a nice transition out of its Sleepsack wearable blanket. The exact cut has changed a bit through the years; we like that this current version isn't too bulky. It zips up from the bottom under the assumption that you're still handling your toddler's diaper. Once your child is in pull-up diapers or potty training you'll want to transition out of a sleeper like this one.
