Aden and Anais Sleep Sack Sizing & Review

This post may contain affiliate links.

One day when I was waiting in the midwife’s office for one of my appointments, there was a woman there waiting for her 6-week appointment. We had the opportunity to talk about a variety of topics and one of those was the blanket she was using. This was my introduction to the world of the Aden and Anais Sleep Sack.

I didn’t know how one brand would become such a staple in our lives for the next few years.

The Classic Aden and Anais Muslin Sleeping Bag has been used with both of our kids. It’s a bay bedtime staple for a few reasons.

Aden and Anais Sleep Sack

Both of my kids loved being swaddled but once they started rolling over, we needed an alternative. I wanted a blanket that would stay on but one that also gave them the freedom to move their arms.

There are three varieties of the Aden and Anais sleepsack available:

Classic Sleeping Bag
Silky Soft Sleeping Bag
Cozy Sleeping Bag

Since we live in South Texas, the Classic Sleeping Bag works well for us. It’s a wearable blanket that zips up from the bottom and goes over your child’s pajamas.

Classic Aden and Anais Sleep Sack

I love the fabric and the functionality that comes with the features of the sleepsack.

100% pre-washed cotton muslin
breathable fabric
machine washable
four sizes available (small – extra large)
variety of prints available (boy, girl, and gender neutral)

This sleep sack eliminates the need for loose blankets in the bed which makes me feel safer. The muslin fabric is also extremely breathable which allows the baby’s temperature to regulate easily.

All of the styles follow the same Aden and Anais size chart. The differences are in the materials used to make each sleeping bag.

Cozy Aden and Anais Muslin Sleeping Bag

The cozy sleeping bag is 4 times the thickness of the classic line to help keep babies warm during cold nights. If you live in a climate that gets chilly and want an option to loose blankets, the cozy muslin sleeping bag is a great option for you!

It’s made from premium flannel muslin that is made from 100% brushed cotton and is filled with a hypoallergenic fill. It’s a first of its kind material and I love that Aden and Anais are working on innovative new materials for our babies!

That means that it’s washable and stays soft no matter how many times you wash it!

The sizing on this sleeping bag does run a bit small. So be sure to take a look at the Aden and Anais size chart we have further down in this post.

Silky Soft Aden and Anais Sleep Sack

If you’re a fan of something with a bit of fancy to it, the Silky Soft sleeping bag might be a good option!

It’s the Classic Aden and Anais sleeping bag with a metallic makeover. The prints are still soft, but they’re also shimmery!

You get the same features of the classic sleeping bag but the muslin is combined with the luxurious softness of vicose made from bamboo.

These sleep sacks are amazing but they do have special care instructions that you’ll want to look at before washing!

Aden and Anais Sleep Sack Sizing

All of the sleep sack styles are available in sizes small, medium, large, and extra large. The cozy sleeping bags do run small, so consider that when you’re buying them.

Here is the Aden and Anais sleep sack sizing for both the Classic and Silky Soft product lines:

Note the difference in measurements on the Aden and Anais size chart for the Cozy sleep sacks:

We found the Aden and Anais sleep sack size charts to be accurate for finding the right sizes for our babies. I love that the design of the sleep sacks means that there is plenty of room for your child without adding blankets to their bed.

Oh, and although it’s not important to the functionality of the Aden and Anais sleep sack, I do appreciate that they come in prints that coordinate with other Aden and Anais products. They make great baby shower gifts! It’s so easy to put together a gift of a sleeping bag, coordinating swaddle blankets, and more!

You can learn more about all of the Aden and Anais products on their website.
