Grows With Your Baby
Designed as a universal size sleep sack to fit babies from 2m-2yrs. No need to buy a new size every few months!
Love my baby’s ecolino. I love that it’s going to fit him up to 24 mo old so that I don’t have to purchase others as he grows since babies grow so fast.

Just bought a second because we loved the first so much! As a second time mom, I'm all about something that lasts more than 3 months. I love the fact that it's longer so we get more use out of it. Anyone who has been around the block knows how fast kids grow out of EVERYTHING. The additional snaps under the arm keep the sleep sack in a secure position until baby is bigger. It's been great for night time changes and we even keep it on for bouncer time because it has the slit for buckles/belts. Beyond satisfied with the material, weight and design. I rarely recommend products to other moms but this is one I would add to my short list.

The Ecolino adjustable sleep bag is perfect for summer! My baby sleeps so well in the the sleep sack along with either a long sleeve onesie or short sleeve onesie. Sleep sack feels light but cozy.
Adriana M.5/5Verified
Super cute, high quality, and keeps my girl warm at night. We love it 💛
Nicole F.5/5Verified
Love the elegant sleeper! It’s beautiful and soft to touch. Most importantly clean fabric!
Marina Y.5/5Verified
Unprofessional packaging. I ordered this sleep sack as a gift for a baby shower tomorrow and now I will be returning this and going to Target to get a Halo sleep sack instead. Honestly I’m not surprised when I order from Amazon and my boxes are crushed and typically it doesn’t matter because I’m using the product. However, since I ordered directly from the company I expect the product to look decent upon arrival. This was purchased as a gift and I’d feel disgusted if I were to give the mom this packaging as it looks used/mishandled/mistreated. Highly disappointed would not recommend.

I love this Woolino Ecolino Organic Toddler Sleep bag. The fabric was really soft. 👌 It is a little heavy which I think it's very good because my child jerk a lot when sleeping which made him toss and turn when sleeping and the blanket would get off his body. The zipper is one of the great key for wearing a this sleep bag. Easy access to put my child in and out of the sleep bag. Overall, I really love it. ❤️
Nhajo S.5/5Verified
I really love the design of the product. Oh, quality is 100%. The first time using it, our little one slept longer than usual. It kept him warm and cosy.
Maryam S.5/5Verified
We love this sleep sack! My son hates blankets and any covers, but he loves his sleep sack! He looks forward to putting it on before bed too. It's easy to clean and I love that the cotton is so breathable.
Jordan B.5/5Verified
I absolutely love these cotton sleep sacks. A slightly more affordable alternative to some competing brands, more sustainable and lasts so much longer being size 2-24 more months. I bought these because another well known brand we were using was getting lots of holes in the lining and my daughter was getting her feet stuck in the lining while sleeping and waking up crying s these don’t have that lining and are still the perfect amount of warmth for her. I love the shoulder snaps and all around zipper. I would definitely buy this again.

I purchased the 4 season Ultimate Sleepsack, 3- Ecolino Organic Cotton, and 2-4 Season Basic Sleepsack. As a gift for my grandson & a friend. After 6 grandchildren and purchasing “several”sleepsacks from various brands; due to wear and tear, and outgrowing them. I did some research on sleepsacks and came upon Woolino. Read the reviews on how they’re made, I made the decision to purchase the Utimate 4 Season, & Ecolino. My daughter was a little apprehensive of the word “wool.” After using them she absolutely “loves” the quality and not having to frequently replace them as the child grows. She really likes the idea that the word “wool” doesn’t represent “itchy”🤣. She lets all her friend know about them and they are worth the dollars. I wish I’d known about these prior to my first grandchild. Love Woolino line.
Sincerely,
Nana

We love the organic cotton sleep sack! We have both the wool liner and the cotton one and they’re both made so well! We love this one for year round- it’s a thick and soft cotton!
Jaclyn H.5/5Verified
The sleep sack is soft, easy for diaper changes and most important to us, organic cotton. It’s got a clever snap under the arms that doesn’t allow the neck to ride up onto our baby’s face- so it’s also safe.

I was so excited to see Woolino come out with an Ecolino 1 tog cotton sleep bag in 2-4y sizing and it has exceeded my expectations (like all Woolino products do!) I have the .5 tog Ecolino sleep bag in 18-36 month sizing and love it but also needed a 1 tog. I searched for a long time for a 1 tog cotton sleep bag that came in a toddler size (most 1 togs seem to be made of micro fleece, or are cotton/bamboo but have a filling, or only came in footed versions, or just weren't long enough.) 2 layers of cotton are perfect for 1 tog. The fabric is wonderfully smooth and soft. It feels so soft, breathable, and snuggly. Beautiful stitching, amazing print, and the temperature range is perfect and very accurate. My 16mo has been sleeping in this with a long sleeve cotton onesie underneath, and his room is around 71 degrees F in the summer (air conditioned with a fan on low on the other side of his room.) This sleep bag is truly unique. You will love it!

My baby rolls around in his crib all night and wakes up when his legs get caught between the rails. At my 9 month check up, my dr suggested a sleep sack. Even if you get mesh bumpers, she said babies can still get caught and tangled, especially when they start to climb. After a Google search, I noticed cheaper ones were not made as nicely. I love that Woolino has sacks that can grow with the baby so you don’t have to buy multiple sizes. It’s a nice weight. Made well. GOTS certified which is important, especially since he has excema. Isn’t to hot for my babe in the summer as I just have him in a diaper when he wears it. Definitely recommend, worth the price!

I just bought this and let me tell you my son really likes it! The smile on his face shows it! We have yet to sleep in it due to we just got it today but I just had to come on here until everyone how great it is! Because they have so many different options to choose from I wasn't sure which one to get miss one or their basic sleep Sack or the footed sleep sack I really wanted the Merino wool sleep sack but I wasn't sure on the quality and the fit and if my son would like it so I decided to go the cheaper route and just by the cotton one to try out I can only imagine how nice the marina wolf would be! So I definitely will be buying the two other versions in Merino wool! I would order them right this second if my fiance would let me LOL I wish they made them for adults really I wish that they made the Merino wool toddler blanket in a adult size I really do believe they would make a killing. I would give this 20 Stars if I could

Soft and breathable. My baby loves nap time in this. The color way is great too.
Liz T.5/5Verified
We purchased the desert color infant-24 months cotton woolino (with snaps). It was not nearly as soft as the regular cotton zip up striped blue and white one. I am not sure if the material is changed for the ones that adapt for older babies.
Orli H.4/5Verified
We have a tough time keeping the nursery cool. The ecolino keeps the kids much cooler overnight. They are so happy in them!
Conor W.5/5
My baby love this product. Is super soft and great quality. A must have for sure.
Grace T.5/5Verified
Just got this for my 4 month old baby. I love it!! It is long to grow into which will save money in the long run not having to buy multiple sleep sacks. The snaps also help her fit into it comfortably now. The organic cotton was important to me and why I found the product - it is not too thick & not too thin and I think it’ll provide year-round comfort. It is also very soft - softer than I was expecting. I would definitely buy this again and recommend to others!
Carly R.5/5Verified
We keep our house pretty cold at night and our baby always seems so comfortable and cozy in the sleep sacks without getting too warm. I tried one and we loved it so I have since bought more.
Michelle K.5/5Verified
My little one has been using woolino sleep sack for over a year. It's the only one that he really liked and I love that it is made with non toxic materials. He outgrew the initial one I purchased so i just purchased a second one for his next growth stage bc we love it so much. Thanks for an incredible product.
Jamie H.5/5Verified
That was the best purchase for my baby. He really enjoys his sleep in this bag. Very soft and comfortable fabric and beautiful desighn.
Hripsime C.5/5Verified
The blanket is phenomenal. The quality is great and it is just light enough to be used through the summer since our upstairs gets a bit warm. Great product and well worth it.
Sajawal S.5/5Verified
I love the woolino sleep sacks! My baby is super comfortable while she sleeps and stays warm and cozy. One of the things I love the most about them as a mom is that I don’t have to worry about her chewing on a zipper because the zipper is on the side, not up by her mouth like most other sleeps sacks. That gives me peace of mind while her and I both sleep.
Kristen V.5/5Verified
No blowout stains visible with this color! We keep our house within the temp range year round, so we didn’t need to get the 4 season version. We love that this one has more relaxed care instructions, and it’ll last til she’s 2! The sleep sack feels well made, so I expect it’ll last until she’s 2 and can the be used by her next sibling!
Heather G.5/5Verified
I love the Ecolino sleep sack. It washes well and my baby seems to enjoy sleeping in it. I ordered the Woolino too, and I regret it. We only use the Ecolino and it was half the price! I wish I would've just ordered 2 of these instead.
Lisa L.5/5Verified
I love this pattern. It’s so cute! I got two of these sleep sacks so when one is dirty the other is available. Just the right thickness and warmth!
Elisa H.5/5Verified
Love these sleep sacks. My baby sleeps comfortably without getting too hot or cold and we keep our home between 68-72 degrees. It’s very soft and 100% cotton which I love.
Elisa H.5/5Verified
Super soft and cute and easy to get on and off of my baby!
Danielle R.5/5Verified
We loved the all seasons sleep sack and now are very happy with our new sleep sack for 2-4 year olds now that my younger daughter is 2.
Ally T.5/5Verified
Ich bin sehr zufrieden , sehr schöner Schlafsack für unseren kleinen.
Hatte schon den, bis 2 Jahre ….
Immer wieder gern .
Melanie G.5/5Verified
Soft, high quality, and does exactly what it’s supposed to! Our little one transitioned out of her swaddle to this wearable blanket with ease. She’s four months, and we plan to keep using it as long as she fits. We bought two so we could rotate them.
Hannah O.5/5Verified
Love this sleep sack! The material is soft and warm, yet breathable. As my baby is growing so fast, I appreciate that he will be able to use this for quite a while.
Merry H.5/5Verified
Awesome
Rayza Z.5/5Verified
This sleep sack is probably similar quality to most sleeping sacks on the market. It’s on the thinner side. It isn’t a good substitute for the wool sleeping sack. I’d say invest in the 4 season one for peace of mind that baby is warm in cooler months.
Tamia M.4/5Verified
So soft and love the adjustable sizing!
Sima S.5/5Verified
Great sleeping bags with great quality. I would recommend them!
