Best Baby Sleeping Bags and Sleep Sacks with Sleeves

Parents are always looking for ways to improve their baby’s sleep and keep them safe at night. Sleep sacks solve both of those headaches! Loose blankets in a baby’s crib or bassinet are a big problem and the American Academy of Pediatrics advises against using any loose blankets with infants during sleep. If blankets go over the baby’s face or tangle them up it creates a SIDS risk.

Sleep sacks are wearable blankets you can use with your baby that don’t tangle or move over the baby’s face where they’re not supposed to. If your nursery is on the cooler side at night you might be looking for a sleep sack that has long sleeves to keep your baby nice and comfortably warm. There are even a couple of baby sleeping bags on the market that are suitable for camping in cool weather that we’ll take a look at, in this article.

Understanding TOG

It’s important to understand the rating system ‘TOG’ when looking at which sleep sack with sleeves you will need for your baby’s room. TOG stands for: Thermal Overall Grade. The TOG tells you how thick the sleep sack is, which will tell you how warm it’s going to keep your child. The higher the TOG rating, the warmer the sleep sack will be. You will need to know your nursery temperature so you can make a good decision about the appropriate sleep sacks that will allow for safe sleep. Make sure you check your baby’s body temperature by feeling baby’s skin on the back of their neck and also making sure they’re not sweating. Cooler is safer than hotter.

Best Baby Sleep Sacks With Sleeves

This list is for sleep sacks you would use at home with your baby. They’re not really suitable for camping in cold weather like a true infant sleeping bag; I’ll cover that in the next section. Sleep sacks like this that have sleeves are helpful to let your baby feel contained and help suppress the startle reflex that he or she may not have grown out of yet. These sleep sacks with sleeves are also warmer than a standard sleep sack with no sleeves.

Love to Dream

Love to Dream is a brand I’ve had great success with for my own children. My babies have preferred having their arms up high near their face as they sleep, which is more natural for babies in utero while you’re still pregnant with them. The Swaddle Up Transition Bag is one I used and loved. All of these options have double zippers for easy diaper changes, which is so handy when you don’t want to fully undress your baby in the middle of the night but they need a diaper change. Love to Dream has a variety of fabrics available for warmer climates and for cold nights. Their ‘transition bag’ and ‘transition suit’ are a great option for young babies who still have a startle reflex. Older babies might enjoy the regular sleeping bag or sleep suit featured below.

Love to Dream has a wide variety of sleep sacks available to ensure you can keep your baby at the right temperature. Most of their products are available in Lite, Regular, and Warm options.

Halo Sleep Sack

Halo Sleep Sacks are a good choice for mild temperatures. They offer one sleep sack with sleeves that’s 1.5 TOG, which is good for about 72 °F/ 22 °C. Their unique inverted zipper allows you to change your baby’s diaper without undressing them completely and then becoming cold. This sleep sack covers your baby’s feet and the company also has many sleeveless sleep sacks for warmer temperatures to choose from.

Zipadee Zip

Not only does the Zipadee Zip have sleeves, it actually covers your baby’s hands as well. This helps ensure your baby stays nice and warm and helps reduce their startle reflex, when you’re transitioning out of a tight swaddle into a sleeping bag like this. I’ve used the Zipadee Zip with my own children and can definitely recommend it. This company offers three different levels of warmth, including a super breathable material for their ‘lightweight’ fabric options.

  • Pros:
    • Covers arms and hands
    • Reduces startle reflex
  • Cons:
    • Fabrics tend to ‘pill’ after usage and multiple washes
    • Zipper isn’t inverted or two-way which means you have to fully unzip sleepsack to change your baby’s diaper

Merlin’s Magic Sleep Suit

I have a few mom friends who swear by using the Merlin’s Magic sleep suit to transition their baby from a tight swaddle to having baby’s arms out and free during naps and overnight sleep. It’s a lightly padded sleep suit stuffed with polyfil that helps muffle your baby’s movements and startle reflexes. When you need to wash it, it takes a long time to dry and might not be ready for baby’s next nap or bedtime so having a spare suit is suggested. 

Check the price on Merlin’s Magic Sleep Suit on Amazon

  • Pros:
    • Double zippers to help get baby in and out easily
    • Greatly reduces startle reflex
    • Quilted with polyester fill 
    • Micro fleece fabric options
    • Cotton fabric options
  • Cons:
    • Expensive
    • Takes a long time to dry because it’s quilted
  • Washing Instructions:
    • Machine wash cold and tumble dry low (hang dry will prevent shrinking)
  • No TOG rating available

According to the Merlin Magic Sleep Suit website this product doesn’t have a TOG rating: 

“because it is not enclosed like a sleep sack.  The design with the open hands and feet allows babies’ heat to dissipate as they sleep unlike a swaddle or sleep sack. We recommend dressing the baby in a diaper or a onesie under the Magic Sleepsuit – no more than one layer of light cotton.”

Hudson Baby

Hudson Baby makes a wearable blanket with sleeves. This brand even makes their long sleeves sleep sack with built in mitten cuffs if your baby is young enough to worry about scratching their face this could be the perfect choice for you. This baby sleep bag has fantastic reviews online and the polyester filling has almost a lightly weighted blanket effect.

Gunamuna

This sleep sack from Gunamuna is filled with hypoallergenic microfiber fill and features a 4 way zipper design for easy diaper changes, also making it simple to put baby in and out of the sleeping bag. The fabrics used are Certified OEKO-TEX® Standard 100. This means it’s safe and gentle on baby’s sensitive skin as well as guaranteed free from harmful chemicals, toxins and irritants.

The organic cotton style has removable sleeves. The bamboo blended muslin fabric option is filled with Sorona.

Hopefully your baby’s room isn’t ever getting this cold, but the warmest sleep sack from Nest Designs might be a good fit for cool weather camping, which we will look at more in depth in the next section coming up.

Best Baby Sleeping Bags For Camping:

This section features three baby sleeping bags that are advertised as being safe for cool weather camping. It’s more challenging to dress a baby appropriately for camping since the weather can fluctuate through the evening and overnight. You’ll need to keep a close watch that your baby isn’t either overheating or getting too cold. Feeling the chest or back of your baby is the best indicator of how warm or cold they are while they sleep.These products can help you dress your baby for a good sleep at a comfortable temperature. 

Morrison Outdoors

Morrision Outdoors is one of the only companies out there that makes a sleeping bag suitable for truly cold temperatures you may encounter when camping. They have a down-filled option for cold weather and a synthetic-filled option for slightly more mild temperatures.

Baby Deedee 

Baby Deedee is another company that offers a sleeping bag for mild to moderate temperatures you may encounter when camping. Their product is 100% polyester and doesn’t offer the same protection from truly cold temperatures like a down-filled sleeping bag would.

Ergopouch

Ergopouch is one final sleeping bag option I had to mention because of their unique zipper design. If your child doesn’t want to get out of their jammies in the morning, or you need a quick walk to the outhouse in the middle of the night, you can zip the legs apart so your child can walk while wearing their sleeping suit.
