Durable, Warm, and Worth the Investment
We’ve been using this wool wearable blanket for nearly two years, and it has been fantastic. The material is soft and breathable, keeping my child perfectly warm during the winter and even on camping trips. It fits well and is flexible enough to accommodate a wide range of ages. One of the best features is that it allows my child to walk comfortably while wearing it, which was a major factor in choosing this product. After many washes in the washing machine (we hung it to dry), the blanket has held up remarkably well. There’s only one small hole, likely from a toenail, but considering how long we’ve used it, I’d say the durability is excellent. Although it is on the expensive side, we’ve definitely gotten our money’s worth, and it’s now being used by our second child. Highly recommend it for anyone looking for a long-lasting, high-quality wearable blanket.

Great quality!
Do it! This sleep sack has been a game changer! We got it in the summer this past year and it has been great for our 1 year old as he was standing and walking. I was always worried he would faceplant in the sleep sacks, so this puts my mind at easy since it has leg holes. In the warmer weather, we use normal footie PJs or throw on a pair of socks. In the fall and winter he wears fleece footie PJs and is very comfortable. I love that it has grown well with him and we look forward to using it for the rest of this year (or longer). Easy to care for, zipper is sturdy and my baby likes to chew on it, it has a great zipper cover, looks cute, easy to wash, and fits great. It's got a great amount of weight to it. He sometimes carries it around like a blanket because he loves it so much. I wish I bought one sooner and saved money on buying sleep sacks every couple of months

LOVE IT
THE perfect sleep sack for my toddler. She loves it! Im thinking of ordering another one. The quality of the fabric is amazing, it washes great, and the material is just right, not too hot but cozy enough for year round use. I love it.

Phenomenal quality! So glad I splurged
I cannot say enough positive things about this sleep sack. I bought the size 18-36 months with feet, and my 7 month old fits the guidelines for it being safe to wear (his head does not fit through the neck hole, he’s a big boy) and the roominess is amazing. No more kicked off blankets. No more chilled baby toes. I love that it comes with a dressing guide and thermometer! What an awesome feature. I hung the thermometer on a door handle by my diaper changer and can easily see what temperature it is, flip it over, and get suggestions for what layers to put on my baby so he doesn’t get too warm or too cool underneath this sleep sack! It is lightweight, but heavy enough to feel robust and comforting. The cotton and wool blend is nothing less than luxurious. I’ve had multiples times I had to wash this sleep sack, as my little one still spits up quite regularly. It was daunting at first, but really cleaned up perfectly. I used 1 Tbsp of eucalan’s jasmine scented wool wash called “wrapture” and put it in my washing machine for a cold rinse and spin cycle on delicate and then hung to dry. It is such a perfect weight, it dries quickly without being cumbersome. I gave it a quick 10 minute fluff in the dryer and it was back to cuddly super soft and ready to go again the same day. I cannot day enough wonderful things about this sleep sack! It’s definitely a keeper!

You need this, no matter what the climate is where you are!
The best! Anyone with a toddler should own one of these when transitioning from 'bag'. I'd wondered how it'd fit/work d/t the harem sort of cut. It works great, once on it looks like the kid is wearing a long skirt with little feet poking out. Can we say adorable?? This was for a grandkid visiting Vermont; warm enough with regular pjs underneath. Once he returns to Hawaii he will still be able to use it with less or nothing but a diaper underneath. About the weight of a merino kids basel-layer, soft, zipper great.

High quality
I’m so glad I found this baby sleeping bag! The quality is excellent—soft, breathable fabric that keeps my baby cozy without overheating. My little one used to kick off blankets constantly, but since switching to this sleeping bag, he’s been sleeping more soundly and safely.

Best of both worlds, benefits of woolino sleep bag with added ease of movement, but not without flaws.
Update: Daughter is now 18 months and 96th percentile for height (almost 34 inches) and it's still large on her, lengthwise. Or rather it's just the issue of the cuffs, which are loose and not stretchy, so I have to roll them up if she wants to walk around in this thing. They don't stay rolled up very well though so I have to keep an eye out to make sure they don't unroll and trip her up. I might take the cuffs off and sew new ones on. If the cuffs would just stay around her ankles, it'd be fine, since the actual blanket part if a couple of inches off the ground. That said, I think it's the best option out there. My daughter hates hates hates regular blankets but often refuses to be changed out of this thing in the mornings. Original review: So happy that Woolino started making sleep bags with foot holes! It's the only reason I wasn't buying a sleep sack before. My daughter has a floor bed and thus has access to her room if she gets up and wants to play. Now I know she's nice and warm but also has the option to walk/crawl around without tripping. She's almost 11 months (85th percentile for weight and height) and I do think it's a bit large, considering it's sized for 6-18. I have to hike up the leg cuffs, roll them a few times, and then secure them by rolling her pajama pant legs up over all of that. Seems to work okay for now. I wish the leg cuffs were not so loose though so that they would stay above her feet. As it is now, they slide down and she would definitely trip (hence the elaborate cuffing). Other than that, I love it! And I guess it'll probaby last us a while. Im guessing past 18 months. Our heating is a bit inconsistent and I was actually afraid she was going to be too hot in this (with woolino pajamas underneath) but she seemed very comfortable in the morning, not cold and not sweaty at all. Worth the money!

Es un producto de primera calidad, por lo tanto es caro pero me parece una inversión que vale la pena sobre todo en tallas de 6-12 y más. Vienen amplios por lo que les duran a los bebés y mi chiquita no pasa frío. Tengo dos por el momento y me parecen excelentes, tengo otro bebé chiquito y compraré dos mas cuando los necesite.

magari il prodotto è molto buono, pero sinceramente non vedo tanta differenza della utilità con il sacco nanna comprato da ikea...

This sack is perfect! I bought it for my 2 yr old for camping. They’re huge and by reading the measurements listed I sized down. I’m glad I did! Worth the money for sure

ウールとは思えないような肌触りで驚きました。 (個人的にはスーピマコットンを連想させるような柔らかさ) あまりこういったタイプの寝具を着せたことがありませんでしたが、足先が出るからか本人も嫌がらずに着用してくれました。 うちの子は足が強く布団を蹴飛ばしてしまうので、このタイプは寝冷えさせずに済んでとても助かっています。 スリーピングバッグの中に着るものを調節すれば布団も要らず、オールシーズン着用できるというところもとても好ポイントです これから長く愛用させて頂きます
