6 Best Toddler Sleep Sacks, Tested by Kids

After testing several sleep sacks with my 22-month-old son, I can confidently say that the Halo Wearable Blanket stands out for its exceptional performance across all areas. I particularly loved how easy it was to use—putting this sleep suit on my wriggly toddler was a breeze. One central two-way zipper runs almost the entire length of the sleep sack, and it glides effortlessly and quietly, making diaper changes a breeze without disturbing my son’s sleep.

A fabric tab covers the zipper in the same ultra-soft bamboo fabric as the garment, so that it doesn't irritate your child's neck, and the sleep sack is easy to open and lift up to change diapers. However, since my 22-month old just started using the potty, it would be a little cumbersome to leave on during potty breaks. On the plus side, I’m confident that with a bit of practice, my toddler will soon be able to zip it up on his own.

The breathable bamboo fabric is another major highlight, earning this toddler sleep sack a 10 out of 10 score for materials. The bamboo viscose feels buttery soft and I love how gentle it is against my son's skin. On top of being incredibly comfortable, the fabric is durable. Even after several wash cycles, the sleep sack hasn’t shrunk, pilled or lost its luxurious feel. And bamboo is breathable enough for a wide temperature range, keeping my son perfectly comfortable all night long. With that said, the 1.5 TOG rating is ideal for cooler months, offering the right amount of warmth without overheating.

This sleep sack, while slightly oversized, was still a great fit for my 22-month old. I chose the 18-24 month size for him (designed for kids that weigh between 26 and 36 pounds) and it fit him well. There was excess material at the bottom, but it wasn't as much as other sleep sacks that we tried. This left room for growth, but not excessively. The sleep sack fully encases your child’s lower body, which some parents prefer as it can help reduce the risk of crib climbing. Due to the footless design, oversized fit and slippery fabric, walking was a challenge, but my son was still able to stand up in his crib. All in all I was happy with the fit, awarding it a 10 out of 10 score.

At under $40, the Halo Wearable Blanket offers exceptional quality and comfort that far exceeded my expectations. With its soft, breathable fabric, user-friendly design, and lasting durability, it’s my top pick for parents looking for a toddler sleep sack.

Looking for a toddler sleep sacks with feet? The Tealbee Dreamsuit is a wearable blanket with legs that offers your child full mobility at bedtime. I tested it with my 22-month-old son, and my colleague Korin also used it with her daughter. The result? We both liked the fact that our kids could comfortably walk around in the sleep suit without falling over their own feet.

The Tealbee Dreamsuit was incredibly simple to put on my little guy, earning it a perfect score for ease of use. The leg openings are roomy enough where they were simple to slide on my wiggly toddler and the arm openings were easy to slip over his shoulders. I was able to put this sleepsack on my son while he was sleepy and I think in due time, he would be able to do this himself. Korin agreed with my assessment and also noted that “the zipper runs the full length of the bodice making it easy to zip up and down.” The two-way YKK zipper is smooth, quiet, and incredibly convenient for diaper changes, with a protective tab at the neck to prevent irritation.

The fit of the Dreamsuit is fantastic. I love that it is a little oversized (I got a 2T-3T and my son is primarily in 3T), making it super comfortable for my little guy. There were no gaps in the arms or leg holes and I like that the leg holes had a cuff for a tighter fit around the ankles, but not too tight. This is definitely something my baby could grow in—it is a little large for him, but not so large that it would pose any discomfort. There was plenty of room for his full morning diaper and while there's some excess material at the crotch of the sleep sack, my son could still comfortably walk around without tripping. Korin was equally impressed and said: “It fit my daughter well, and left plenty of room in the legs and gusset for her to grow into, without feeling like she would trip over it.”

In terms of material, the quilted bamboo-cotton blend felt incredibly soft, resulting in yet another 10 out of 10 score. It held up beautifully in the wash without shrinking or pilling. Both of us noted how plush and cozy the fabric felt—Korin compared it to a beloved T-shirt or blanket.

I would definitely recommend this toddler sleep sack to other parents. It’s super-soft, comfortable, lightweight and my son slept great (all night!) while wearing it. And he was able to move and play freely with the leg design.

Size range: 12M-2T to 3T-4T | Material: 70% bamboo rayon/30% cotton | TOG rating: 0.8 TOG | Care instructions: Machine wash cold gentle cycle. Tumble dry low heat gentle

The Bublo Baby Toddler Sleep Sack with Feet is hands down the best budget-friendly sleep sack I tested—and one I’d confidently recommend to any parent looking for affordability without sacrificing comfort or quality. At under $20, it offers many of the features you’d expect from sleep sacks retailing at twice the price.

My 22-month-old son had full freedom of movement in this sleep sack, walking and playing comfortably before bed and in the morning. The two-way zipper glides smoothly without catching the fabric and makes diaper changes quick and simple, although it was a bit louder than others I tested. It’s also incredibly easy to get on and off, even with a wiggly toddler.

Made of 100 percent cotton, this sleep sack was ultra-soft and comfortable. The quality of the garment is great for the money—the fabric and stitching seem like they’ll hold up beautifully in the wash and with extended use over the next several months. There are internal tags (which I don't love), but they are soft and can be cut close to the seam, which I will definitely do to avoid any annoyance for my toddler. The design is sweet and simple. My son especially loved the star print, pointing to it and smiling at bedtime, which made the whole experience even more enjoyable.

With its solid fit, breathable fabric and toddler-friendly design, the Bublo Baby delivers outstanding value with many design features found in pricier sleep sacks. For parents on a budget—or just looking for a great everyday option—it’s a smart, reliable pick.

Size range: 3-6M to 3-4T | Material: Cotton | TOG rating: 0.5 TOG |Care instructions: Machine wash

The Ergobaby On the Move Sleep Bag stood out as the easiest sleep sack to put on during testing—earning a perfect 10 out of 10 score for ease of use. Korin particularly appreciated the smart combo of adjustable shoulder snaps and a smooth two-way zipper, saying: “There are adjustable snaps at the shoulders that grow with your child, along with a full zip down the front to make diaper and pull-up changes easy.” Her daughter could be zipped in quickly, even when squirmy and the fit adjusted as she grew.

This convertible design also earned praise for its versatility. With a simple snap at each side, the bottom can transform from a traditional sleep sack to one with legs, offering flexibility for bedtime or active mornings. While Korin didn’t need the seatbelt slot, she noted it would be a nice feature for families on the go.

The sleep sack scored highly in all other categories as well, including material quality, washability, and style. Made from soft mid-weight cotton with reinforced piping, it held up well in the wash—”I just tossed it in with the rest of the laundry in the washer and dryer—that was it,” Korin explains. “It didn't shrink or pill in the wash, and there were no snags, despite being washed with velcro-heavy ice hockey equipment.”

The sleep sack is generously sized to fit a wide age range from 6 to 18 months or 18 to 36 months, which means it offers a long wear window, but can be quite large on kids at the lower end of that range. Korin noted that while the roomy fit allows for growth, it may feel oversized at first and fits better as your child gets older.

Next up is the aden + anais boutique sleep sack. This pick has many benefits, from its breathable natural material and chic design to the roomy fit that your child can grow into over time. But the real stand-out feature is the clever zipper design that makes diaper changes a breeze. Unlike other sleep sacks, this pick has a long zipper that unfastens from the bottom up, so you can easily change your child’s diaper at night with minimal sleep disruption. The zipper itself is quiet, simple to use and is protected by a soft tab that prevents irritation at the neckline.

Unzipping from the bottom makes diaper changes a breeze. Using it was super simple, with no fiddly openings. The zipper is relatively quiet, which I appreciated. I don't change my son's diapers overnight so I didn't have an experience disturbing or waking him while doing changes. While wearing the sleep sack, full diapers stayed in place without any issues.

The 100 percent organic cotton muslin fabric is incredibly lightweight and gauzy, ideal for warmer months or hot sleepers. I particularly loved the exterior seams, which offer a unique, tag-free comfort that my toddler clearly appreciated—he slept longer and more peacefully in this than in heavier options, earning it a top score for material.

While my toddler did well with this sleep sack during naps and bedtime, there are a few drawbacks. It’s quite oversized, which is an intentional design feature, so that your child has room to grow into it. But as a result there’s a lot of extra length, which created a tripping hazard during early morning movement. And while the zip guard protects well, it can make it tricky to get the zipper started quickly—something to keep in mind if your toddler is squirmy (like mine!)

Still, for comfort and functionality, especially during summer nights or diapering routines, this sleep sack is an excellent choice.

The Woolino is beloved by parents thanks to its soft, temperature-regulating material that's suitable for all seasons. The only downside? A hefty price tag. Mom of four Korin put it to the test with her 12-month-old to see if it was worth the hype. (Spoiler: It is!)

First off, let’s address the fabric composition. The Woolino sleep sack has an organic cotton outer layer and is lined with Merino wool. The Merino wool layer is naturally thermo-regulating, meaning it’ll keep baby warm in winter and cool in summer. Unlike other sleep sacks the Woolino doesn’t have a TOG rating, but according to the brand it can be used year-round as long as the room temperature sits between 63 and 75°Fahrenheit. Korin told us it wasn’t super heavyweight, but thanks to the addition of wool and cotton, it was “a quality piece.” Worried about the wool fabric being itchy? Don’t be—the super-fine knit is actually soft as silk and gentle enough for sensitive skin, “Everything about it is comfortable and versatile, making it a good choice for families who are in search of an organic option,” adds Korin. Given the premium fabric, it’s no surprise this pick earned a 10 out of 10 score for materials.

Even after washing, the fabric showed no signs of wear. “The fabric is durable and didn't pill or shrink in the wash,” says Korin. She was also a fan of the overall style and design of this sleep sack. “It also comes in a slew of pretty patterns and has an overall sleek look,” continues Korin.

The Woolino has a zipper that runs down the full length of the sleep sack. “A second zipper head at the bottom allows you to get in and out for diapering without having to undo the whole thing, which is genius,” says Korin, who found it very easy to use.

The roomy fit offers plenty of space to grow into, which makes it a solid long-term investment. That said, it does limit mobility, so it’s best suited for sleep rather than walking or play. At $109, it’s definitely a splurge—but for families looking for durability, natural materials, and true year-round usability, it’s worth it!

Size range: baby: 2 months to 2 years, toddler: 2-4 years | Material: 100% cotton shell/ 100% merino wool lining | TOG rating: 1 TOG | Care instructions: Machine wash on low (100°F max), use wool or mild detergent.
