A Wearable Blanket for Babies Who Need to Stretch

HALO Sleepsack Wearable Blanket

Sleep sacks come in several different designs, one being a swaddle design, and the other being an arms-free design. HALO is a trusted infant brand that has proven over the years when it comes to sleep sacks, they know what they are doing.

A Sleep Sack for Brand New Babies

Love To Dream Swaddle UP

This wearable blanket takes into account that infants like to sleep with their arms in the sky. It allows them to have limited movement in the upper body region, keeping arms in their natural position while holding them safe and snuggly.

What we like
Allows arms to be inside the sack without Velcro-ing them in.
What to keep in mind
Only applicable for young babies

A Sack That Aims to Regulate Temperature

Includes shoulder snaps AND a zipper
What to keep in mind
Costly

Best Sleep Sack for Chilly Nights

One common complaint with sleep sacks is that they are not as warm as baby blankets.

A Sleep Sack for Babies On-the-Go

HALO Early Walker Sleepsack Micro Fleece Wearable Blanket

Not all little ones hit the sheets as soon as they are placed in their cribs. Once they figure out how to use those little legs, it's hard to keep them down, even at naptime. Traditional sleep sacks can trip tired babies up, causing them to tumble into crib rails. The HALO early walker sleep sack lets babies use their feet, but keeps them snug once they tucker themselves out.

What we like
Allows for movement of feet
Available in several colors
Comes in three sizes
What to keep in mind
Some parents thought the material could have been softer

A Weighted Blanket for Babies

Nested Bean Zen Sack

Babies sleep soundly when they are lying in their parents' arms. You cannot hold them all night long, of course, so consider purchasing a sleep sack that mimics your tender, loving arms. This lightly weighted sleep sack creates a soothing feel for babies who would much rather be held while they slumber, by adding a bit of weight to where a parent's hand would normally rest on their chest.

What we like
Shoulder straps
Gently weighted in the chest area
What to keep in mind
Some parents claim it doesn't work as effectively as they had hoped it would

A Sleep Suit for Sweet Dreams

Baby Merlin Sleep Suit

Because this goes over the baby's outfit during snooze time, it functions like a sleep sack. That said, it is a suit, not a sack. A lot of technology, thought and design went into making this suit that many parents swear has major powers. Its three layers create an optimal atmosphere for little ones to nod off easily, allowing parents to also catch up on a few ZZZ's.

What we like
Thick material
Great transitional suit if you are moving from a swaddle to free-moving arms
What to keep in mind
Not cost-effective, and can only be used for a short span of time
Not optimal if you live in warm climates

A Sack That's Good for Baby and Good for the Earth

KYTE BABY Unisex Bamboo Rayon Sleeping Bag

Protecting the earth is nearly as crucial as protecting your baby. With the KYTE sleeping bag, you can do both. It is made from breathable and ethically sourced bamboo, so you will feel good about purchasing it for your bambino.

What we like
Eco-friendly
Comes in an assortment of colors
What to keep in mind
Material and threading came apart quickly
Expensive

Lightweight for Little Dreamers

Little Unicorn Sleep Sack

Not all parents want heavy coverings on their kids while they sleep, but they want at least something soothing and reassuring in the crib. The Little Unicorn Sleep Sack is made of muslin, so it's very lightweight. The materials only become softer over time, something you don't see with other materials.

What we like
Cutest designs and patterns
Soft material
Perfect for warm summer nights
What to keep in mind
Won't cut it if you live in the chilly north

Part Swaddle, Part Sack

HALO Sleepsack Swaddle

If you want the best of both worlds: combining a sleep sack with a swaddle, then HALO has you covered. Parents can tightly wrap both, one, or no arms inside this sack, securing their infant in the sack snugly.

What we like
Great for babies who need to be tightly swaddled
Can swaddle both arms, one arm, or no arms with this model
Holds up well throughout many wash cycles
What to keep in mind
Won't work for babies who weigh more than 18 pounds
Velcro can be loud and disruptive

A Long-Sleeved Sleep Sack

 Zipadee Zip

Many sleep sacks come sans sleeves, but the Zipadee Zip sleep sack includes sleeves for parents who want their babies bundled up head to toe. The Zipadee Zip gives a sense of swaddling, but allows for some arm and leg movement, making it a supreme product for transitioning from a tight swaddle.

The Only Sleep Sack You Will Need

multi-tog-sleeping-bag-blush-stripe-full.png

The Mori sleep sack is designed to be your go-to sleep sack no matter the time of year or weather. It has removable inner padding for warm summer evenings, and the ability to keep babies warm when the weather turns cool. The sack can go from a 2.5 TOG in the chilly months, to a 0.5 TOG when it's warmer out.

What we like
Interchangeable depending on the weather
Double directional zipper
What to keep in mind
Pricey, especially if you want to own more than one.

A Feel-Good Organic Sleep Sack

Burt's Bees Baby Unisex-Baby Beekeeper Wearable Blanket

Many parents turn to organic products, believing that they are the safest options on the market. Burt's Bees is a longtime trusted organic brand, so it is no great shock that their sleep sack is a huge hit with organic-loving parents. It's lightweight, soft, and safe.

What we like
Easy to use zipper
Excellent value
What to keep in mind
Some parents might feel it is too lightweight

A Super Soft Sleep Sack

Baby Deedee Sleep Nest Lite

Jersey cotton... it's like sleeping in a cloud. While some fabrics pill, become rough, and let you down over time, jersey cotton will love you forever. The Baby Deedee is easy to maneuver, on top of being so, so soft. There are snaps at the shoulders and a large zipper that moves both up and down.

What we like
Soft material
Easy in and out with zipper and snaps
What to keep in mind
Zipper doesn't zip as far down the sack as some parents would like

Could Sleep in an Igloo

Günamuna Sleep Bag

The Günamuna Sleep Sack is literally a safe baby sleeping bag. If you have to be anywhere a chill might be in the air; you need this. The zipper is far above other zippered sacks on the market. It zips and unzips in a 360-degree direction. With a TOG of 2.6, the temps can dip to around 58 degrees, and your infant will stay cozy.

What we like
Super warm
360-degree zipper
What to keep in mind
Not practical for warm weather
A bit pricey

Innovative Sleep Sack

Bitta Kidda Baby Soother Sleep Sack Sleeping Bag Wearable Blanket + Lovey

Bitta Kidda thought of it all. Since it is NOT recommended that little ones have anything in a crib with them, this sleep sack brand attached some bells and whistles to its wearable blanket. It comes with a lovey to help babies learn to self-soothe. It also has a diagonal zipper to make diaper changes a cinch. Fancy!

What we like
Has an innovative zipper
Comes with an attached lovey
What to keep in mind
Some parents found the built in leg straps awkward and unneccesary

Every parent wants their sleeping baby to feel cozy and secure. Help achieve this result by putting your baby to bed wearing a quality sleep sack. Choose the one that best suits your infant's needs, so you can both rest easy.
