My baby absolutely loves this sleep sack. Every other sleep sack before this he woke up with a sweaty back, so we switched to Woolino and he no longer is sweating all night long. The size range and four season wearability makes it well worth the money and I will be purchasing more!

Love the fabric, pattern and softness of the sleep walker. I just wish the legs were slightly tighter so they didn’t fall off all the time when she’s walking and trip

We love it and so does our baby! Takes the stress away from figuring out what TOG to use depending on weather / room temperature.

We love our Woolino sheepskin! We use it for play time and nap time and my son loves the soft touch. He has sensitive skin and does really well being bare skin on his rug. It is incredibly soft!

Love!!!! We have two and they are amazing. Very nice quality and keep our baby warm but never too warm. Definitely worth the money since they can be used for so long and year around! It keeps sleep sacks simple and not complicated to figure out (temperature and sizes).

Love the Woolino sleep sack! It’s soft, well-made, and keeps my baby comfortable without overheating. Expensive upfront, but worth it since it lasts for years.

Woolino offers the perfect sleep sack. We were gifted one, and I ended up purchasing another because our son loves them so much. We tried a few other sleep sacks, and this is the only one he always seems comfortable in. I wouldn't recommend another sleep sack besides this one. It's worth the price.

We love the woolino! The shoulder snaps are super convenient and we love how long our baby will be able to wear it. We will definitely be investing in another.

It is really well made and she seems to sleep really well in it!

Our baby loves the Woolino sleep sack! So cozy, but not too warm on summer nights either. The hot air balloon print is adorable too!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Hot Air Balloon
This sleep sack is amazing!! We love the seat belt slots because a lot of times our kids know it’s time to sleep when their sleep sack goes on, and since we travel a lot, it’s nice to be able to have them wear it on long car rides. I also love the extra space in the arm holes. It’s so nice to only have to buy one sleep sack for ages 2-24 months. We bought way too many for our first son!

My baby loves this sleep sac. It seems to keep him comfortable no matter the weather and the quality is amazing ! It is really big but also that is great as it will allow us to use it for the 2 years it’s states
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Sun
We love it! The materials are so soft and you can tell it regulates their temperature! He sleeps very comfy. The only thing that could be better are the leg opening…they should be tighter…his feet get trapped inside the sleep sack while he’s still running around and he usually falls or gets upset about it! Other than that, it’s a great item!

Love how easy this sleep sack is and how versatile and comfy it is too! Little one slept for 40 minutes on the play mat for the first time
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Birch Gray
The sleep sack is buttery soft, very functional and well-made. We just transited her out from swaddle up. We were a bit concerned that she would not sleep well and mentally prepared that it would take couple of nights for her to get used to the sleep sack. But I think she loves it and she slept through the night even the very first night without a swaddle. The design is super cute. We are first time parents and probably wasted some money here and there buying unnecessary stuff. However, we think the sleep sack is totally worth it. We just bought another one with the snowboarder print per Dad’s request. Hoping the one with universe print for 2 month-2 year will eventually be back in stock ( per Dad’s request too)
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Kitten
We are a very active family and my daughter who is turning two years old soon, can get sweaty feet. I wanted her to have cozy, natural socks on her feet and these are wonderful. After a wash, the color fades slightly - they maintain their integrity and they just become softer. I really recommend these for children, especially if you are often out and about and you want their little feet in natural fiber instead of synthetic.
We love it! At first, I was hesitant to purchase because of the price. But, my baby runs very hot and this sleep sack is always the perfect temperature for him.

This sleep suit is worth the price tag! I appreciate the natural fibers and that this is the only sleep suit I will need to buy for my daughter. It saves me money in the end! I also appreciate the room thermometer that came with the sleep suit, it helps me know the temperature of her room and how to dress her accordingly.
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Lilac
This is our go-to outfit for sleeping! Super soft and breathable with temperature regulation.
I and my daughter have loved this sleep sack! I have noticed that she sleeps much more comfortably and it gives me peace of mind to know that she will not be too hot or too cold! After a month or two some of the stitching started coming apart (as shown in the photos) and got worse as time went on with the seam binding ripping off. It was so easy to file a warranty claim and I got a replacement quickly! I would highly recommend going with Woolino when choosing a sleep sack for the top tier quality and the amazing customer service! I will be recommending them to everyone!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Rainbow
I’ve got a tall baby and I also value natural fibers, so this is the perfect sleep sack for my little guy. He was growing out of other brands, so I am happy to invest in these knowing they will be the only sleep sacks I will need for a long time. They are super soft, and I love that they came with a thermometer card and advice on what to put underneath them. Very helpful! Would highly recommend and will likely buy more!

The gown is very soft and color is as-expected. I washed it once and air dried it... All seems good! Have not used it on baby yet... :)
The Woolino Ultimate 4 Season Baby Sleep Sack has been one of my favorite baby essentials! The merino wool and organic cotton feel incredibly soft, and I love that it helps keep baby comfortable without constantly worrying about overheating or getting too cold. The two-way zipper makes nighttime diaper changes so much easier, and the quality is outstanding. I also have to mention their customer service—it was absolutely exceptional. I had a delivery issue, and their team responded quickly and resolved it immediately with no hassle at all. Best of all, it’s a long-lasting investment that works year-round and grows with your little one. Absolutely worth every penny for better sleep and true peace of mind! I absolutely would recommend and will (very soon) be repurchasing!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Sage
We got a hand me down Woolino from a friend and had to buy a back up. She used it for 2 kids and you would never know. These hold up so well and are extremely comfortable. I wish I knew about these with my other 3 kids. My son loves this sleep sack he grabs the extra material and cuddles it, but safely since it can not get close to his face.
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Navy Blue
Love it! We used the 4 season classic with our first baby and the ultimate sleep bag with this baby. I think I prefer the ease and quickness of the classic. This feels nice and secure and fit to our baby but it's annoying to have to do all the buttons every time I put it on. It's beautiful though and I love the print. It's so so soft. Love our woolinos!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Whales
This has been the first and only sleep sack that my baby has been able to successfully fall asleep in and stay asleep independently in her own crib. We will be purchasing another just to have on rotation. Well worth the price considering she will be able to use them until she is 2. We will also use these for our next child as well.
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Sage
Woolino is one of my best purchases. We live in a rather hot climate but our house temperature fluctuates a lot during the night and I always had trouble on what was the best pyjamas or sleep sack. Now I am care free even if its 16 or 22 celcius🙏
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Star Gray
My daughter moves a lot in her sleep so the traditional sleep sack was no longer working for her. She absolutely loves this! She will even ask for her strawberry suit before nap and bedtime. It has improved her sleep so much and I’m no longer worrying about her temperature every night.

My 13 month old loves this sleep sack. It gives him more freedom to move while he is sleeping and has given us more hours of sleep!
4 Season® Baby Sleep Bag with Feet, Merino Wool & Organic Cotton, Puppy
The temperature of our house fluctuates a lot! I love knowing that my baby will stay comfortable all night. It’s also a relief knowing that he can wear this until he grows out of a sleep sack! No need to keep purchasing larger sizes or different TOGs. It’s so soft to the touch. Ive found it really easy to undo for middle of the night diaper changes.
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Teddy Bear
Very soft. Will order more.
4 Season® Baby Sleep Bag with Feet, Merino Wool & Organic Cotton, Teddy Bear
These fare great, they come up on their legs and they stay there!
Our daughter is so comfy and happy in this sleep sack. She tends to run hot and she never gets overheated in it!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Terracotta
These are the perfect sleep sacks!!! Hot or cold it adjusts to keep baby comfortable. The sacks are lightweight and don’t feel bulky like some and still comfortable to burp babies in the middle of the night or to change diapers, the zipper goes all around the bottom also, easy to put on and allows babies to move freely. 🩵🩵
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Panda
LOVE Woolino’s products! My 3rd time purchasing items for my son! Wool works magic for him from birth! He has slept in cotton once in 5.5 month when all his wool pajamas were dirty but never again. Worst night sleep, sweating and uncomfortable.
4 Season® Baby Sleep Bag with Feet, Merino Wool & Organic Cotton, Space - GLOW IN THE DARK
My girl is SUPER tall and we have gone through sleep sacks like it’s nothing because of it!! This one is perfect for her and for my wallet because she has so much room to grow into!! Her room doesn’t hold a lot of heat which has made me panic each night since she’s born on if she’s cold, but she has slept soundly and I have to with the peace of knowing she’s ok either way! We love it!!!
4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Rose

4 Season® Ultimate Baby Sleep Bag, Merino Wool & Organic Cotton, Sheep
I love the fabric. I had to order 2 sizes up. I am usually a medium, but since the reviews said that they run tight, I sized up. Feels good at size XL.
