Ever since my baby outgrew her swaddle, we put her in a Woolino sleep sack.
Then when she turned 2, we didn’t think twice about which sleep sack to get her. We again went with Woolino and stored her old sleep sacks for the next baby.
You probably can tell we really love our Woolino sleep sacks since we have set ourselves to use Woolino’s sleep sack for 4 years!
In this Woolino sleep sack review, I’ll share where we first heard about Woolino, what we love about it and which one you should get.

Using a Woolino coupon code instead of paying full price is definitely a smart financial move to make (but personally, I never used a code and still find paying full price so worth it! Keep reading this Woolino review to find out why.)
Why Use Woolino Sleep Sacks
There are 3 main reasons to use Woolino sleep sacks.
The first and best reason is that, as the name says, Woolino sleep sacks are made of soft merino wool and organic cotton.
The wool helps to regulate body temperature so you can use the sleep sack all year round and you don’t need to worry about tog rating. This is really helpful in ensuring that your baby won’t overheat!
Woolino gives you a thermometer with a guide in one that shows you how to dress your baby underneath the sleep sack.

Second, Woolino sleep sacks are lightweight and so comfortable for your baby.
There’s snaps under the armpits, which prevent the sleep sack from riding up to your baby’s neck and keep them safe.
Third, Woolino ultimate sleep sacks’ universal sizing range from 2 months to 2 years, 2 to 4 years and 4 to 6 years so you don’t need to keep buying sleeps sacks as they grow or as the season changes because of the wool material.
Honest Woolino Sack Review

I love that my childhood best friend told me to get Woolino sleep sacks for my baby when she transitioned out of her swaddle. It was such a good investment that’s going to last well into my 2nd child’s early months.
Before I got the Woolino, I did try another sleep sack and it was a headache trying to figure out the tog rating. I didn’t know if my baby was too cold or too hot but with the Woolino, I know that she’s comfortable all year round.
I also like that I didn’t have to buy any new sleep sacks from ages 6 months (when we first started using the Woolino) to 2 years, and now since my toddler turned 2, we won’t have to get another one until 4, which by then she hopefully learns how to use a blanket. We did try to get her to use a blanket recently but that didn’t go well so we’re sticking with Woolinos for awhile.
Another one of my childhood’s best friend asked me what to put on her 1 year old’s birthday wishlist (since people were asking her for one) and I added Woolino to her list!

Woolino Pricing
Woolino’s sleep sacks range from $79 to $109 (as of 11/28/24) but they are totally worth it because of the universal sizing and the all-season wool material.
Instead of buying a new sleep sack every season or every few months as your baby grows, you can just get the ultimate sleep sack, which ranges in sizes 2 months to 2 years, 2-4 years and 4-6 years. We so far have used the 2 months to 2 years and the 2-4 years!
Woolino sleep sacks are such high-quality that even if they have a few stains on it like ours do, you can save them for baby #2.
Lastly, not only does a Woolino save you money in the long run, the universal sizing saves you the mental load of figuring out what sleep sack to get each season and looking at the features like TOG size, which again, you don’t have to do with the Woolino.

Ultimate vs Basic: Which Woolino Sleep Sack to Get

This is based solely on personal experience but I would recommend getting an ultimate Woolino sleep sack over their basic one.
I may be biased but I like the universal sizing on the ultimate sleep sacks better. There’s a wider range of months that your baby can wear the sleep sack so you don’t need to shop as much.
We got the same sleep sack in the two sizes: 2 months to 2 years, 2 to 4 years and 4 to 6 years.
We like that the ultimate sleep sacks have shoulder snaps, which make it easy to get baby in and out, and underarm snaps for adjusting the size of the armholes and travel slots for use in car seats. This makes it really easy to move your baby around if they’re sleeping.
