You probably have woken up in the middle of the night to check on your baby just to be sure they didn’t cover their head with the blanket.

That nightmare is real for parents because we know babies like moving their little hands even in their sleep. How do you cover them and sleep all night (or at least as much as they will let you) without worrying?

This is it: you combine the construction of a sleeping bag with the softness of a baby blanket, and voila! No, you do not have to go through the trouble, parent.

But, before we get into the business of the day, why do you need a sleep sack for your little one?

Granted, this is the kind of purchase that you may never need again, especially if you are closing the chapter on babies. But there is always someone joining parenthood, and you can always hand it down.

  • Ideal Temperature
    Your baby will not wake up cold and freezing, seeing that they cannot remove the wearable blanket. Most of them are also made of a material that will not suffocate the wearer (read baby).

  • Wiggle Space
    These sleeping sacks are spacious to allow movements. They will not feel as though they are in jail, and so they will sleep soundly all night.

  • Comfortable & Convenient
    Seeing that the wearable blanket has enough space at the bottom, you will not have to wake your baby up for diaper changes. The inverted zips also help to avoid waking them up.

So, you ready for 5 of the best sleep sacks on the market?

1 – HALO SleepSack 100% Cotton Swaddle

The HALO SleepSack saddle, which looks like a long dress, is made of 100% cotton.

This swaddle keeps the arms restrained, but the legs are left free as birds. The baby can wiggle them as much as she wants, which is good for muscle development.

Do you know why this swaddle is good value for money? Because it grows with your baby. When they are still very young, the wrap restrains their arms to prevent startle reflex. It wraps them completely around the entire body to leave you baby looking like an Egyptian mummy!

You will know it is time to transition from the swaddle when they start rolling and trying to push up. The same HALO SleepSack will do. Just stop wrapping their hands and let the rest of the sleep sack stay as it.

It is simple to use. When the baby is ready for bed, dress them in light clothes because cotton is quite warm. You don’t want them being too uncomfortable at night from the heat.

After that, wrap the sleeper around baby’s body and zip it all the way up. If they are below four months, you can wrap it up to restrain the arms.

Things We Liked

  • With the zipper, you will not need to unswaddle them for diaper changes.
  • It is made of 100% cotton.
  • Baby not overheated by fleece material.
  • Fairly easy to put on and remove.

Things We Didn't Like

  • The Velcro sound might wake your baby if need to open swaddle wings for a diaper change.

2 – HALO SleepSack 100% Cotton Wearable Blanket

Still, from Halo, this 100% cotton wearable blanket comes in cream, and it covers the entire body.

Unlike the swaddle, it has no restraints on the hands, and so it is designed with an older baby in mind

By design, it is big to provide plenty of wiggle space. Cotton is usually stretchy, and so you are better off with a bigger one that will contain the baby even when they kick.

You have them in three sizes; small for 10-18 lbs; medium for 16-24 lbs; large for 22-28 lbs; and extra large for 26-36 lbs.

As much as the baby kicks, (they have room for it), they cannot get out of the sack. How is that?

The inverted zipper keeps them in it. It also makes diaper changes easy seeing that you will not need to unswaddle the baby. No Velcro here to wake them up either.

This sleep sack is sleeveless to prevent the baby from overheating. If you fear the arms will be exposed, you can dress them in a sleeved top before bed.

Things We Liked

  • Sleeveless for heat control.
  • The inverted zipper makes for undistracted diaper changes.
  • Really soft, durable yet breathable cotton.

Things We Didn't Like

  • The plastic zipper gets caught n the fabric several times.

3 – HALO SleepSack Micro-Fleece Wearable Blanket

This sleep sack from HALO is light yet warm enough, and it has a wrap for swaddling.

If your toddler still gets startle reflexes even when they are a bit older, you can wrap them with the side wraps designed into this sleep sack. The wrap is fastened with Velcro.

For easy diaper changes, HALO SleepSack Micro-Fleece Wearable Blanket has an inverted zipper that ensures you do not disturb your sleeping baby. HALO has been the preferred swaddle of choice for over 1,000 hospitals, thanks to the material used in their production.

Polyester, which makes up this sleep sack, is fire resistant by nature. The company needs not add any chemicals to fortify the resistance.

The baby has plenty of wiggle space since the sack is naturally big. The company made it intentionally sleeveless for temperature control. We like the wrap on the side that makes it a swaddle as well, which makes its worthy investment.

You will need to dress the baby in a sleeved but light top to keep them all covered.

Things We Liked

  • ​100% polyester micro-fleece.
  • The fleece keeps your baby warm and cozy.
  • The zipper zips up from the bottom making quick diaper changes a breeze.

Things We Didn't Like

  • After several washes the fleece material is not quite as soft as it once was.

4 – HALO 100% Cotton Muslin Sleepsack Wearable Blanket

For those parents who literally flee away from fleece (for being too heavy) this muslin cloth sleeper is for you. It may be just a tad too light for winter, though.

It is 100% cotton, breathable, and as soft as your baby’s skin. The breathability ensures adequate airflow to prevent overheating. You will still need to dress baby up for sleep before putting him in it, especially given that it is sleeveless.

We like the colors because usually, most sleep sacks are plain. This sleep sack breaks that rule to feature warm patterns.

It zips from the bottom for convenience. If baby wants to kick about for his daily dose of exercise, he has plenty of space in this HALO sleep sack.

We have noted that it gets stuck in the washing machine, but nothing that a few tricks would not fix. Before washing it, turn it inside out and throw it in with the rest of the clothes.

Things We Liked

  • Llightweight and ultra-soft 100% cotton muslin.
  • The fleece keeps your baby warm and cozy.
  • The zipper zips up from the bottom making quick diaper changes a breeze.
  • Easy to clean.

Things We Didn't Like

  • Might be too light for winter.

5 – HALO SleepSack Plush Dot Velboa Swaddle

Moving even further away from the plain-textured sleep sacks, this cream-colored swaddle cum sleep sack is polka-dotted and beautiful. It’s made of cotton, which keeps air flowing.

It costs a little more than the sleeper sacks in this review but taking in the material, the 3-in-1 construction, and the leg space it is worth the extra.

When using it as a swaddle, you will notice the Velcro that restraints the baby’s arms without hurting them. If he is too old for swaddling, you can free one hand at a time.

One of the benefits of this sleep sac is that it prevents them from climbing off their crib, seeing that the bottom is not separated. They will have plenty of space to move the legs, and when you no longer need to restrain the arms, they will have the freedom to move those too.

It is 100% polyester, and so fire resistant and warm.

Things We Liked

  • 100% polyester, which is breathable and fire resistant.
  • Sleeveless design reduces the risk of overheating.
  • It is warm enough for winters.
  • The 3-in-1 sleeper comes in 3 different sizes.

Things We Didn't Like

  • It's too warm, heavy for summer.

Conclusion

Most parents, mothers especially, become light sleepers when their babies are born. No parent sleeps soundly with their children tossing and turning in their crib, or worse, crying. A sleep sack allows you to sleep without worrying about a loose blanket suffocating them. In fact, pediatricians discourage parents from using traditional blankets to prevent SIDs.

You will need to look out for the material, the level of warmth so that you are covered in winter and summer, as well as the degree of comfort.

Any of the sleep sacks we have reviewed are excellent for babies, and they will endure long stretches and machine washing. We especially like HALO SleepSack 100% Cotton Swaddle for its multi-purpose ability. It acts as a swaddle when the baby is still too young (between 0 to 4 months), then you can transition them to the sleep sack after that.

Cotton is an excellent breathable material that lasts long, and it is safe for the kid. Some parents feel that it is too light for winter, but you can always get one for that particular season.
