Why Merino?
A study done by University of Sydney, Australia has found that a better night's sleep is achieved when sleeping in or under wool. Significantly finer than other types of wool, merino is the perfect fiber to have next to child's sensitive skin. It breathes, regulates temperature, manages moisture, it is easy to care for, and durable. It is naturally perfect.

I bought this product for my son 6 months ago. He is taller than the 99th percentile and so when he turned 1, I found there were few options for him that were long enough. I had initially bought this product to accommodate his height because at 1 year, he wasn't ready for a blanket. After receiving the product and using it for a week, I bought a second.It is made of a higher quality material than any other sleep sack we have tried. It is thick and cozy, but my son doesnt overheat during the night. Your child can use this sleep sack winter, spring, summer, and fall. The sleep sack washes extremely well and after 6 months the material is as nice as when I initially purchased.The price point initially seemed high to me, but I gave it a try because it was not just so my son could be warm at night, but also so that he could sleep safely, and I could sleep knowing that he was warm and safe! Now that he cuddles up to it in the morning and we have used it every night for the last 6 months, I can emphatically say it is something that is more than worth the price and I highly recommend this product. I had an issue with the zipper and customer service stood by their product and helped me resolve. Its great to find a family business that makes a better product than its competitors.

Excellent sleep sack, we've used this company's sleep sacks for four years now and two children, can't recommend enough!Pros:Amazing qualityKeeps the kids comfortable, warm and cozy throughout the year.I love that it's heavy, as it makes the kids sleep better.Beautiful designs and colors, I have the blue stripes and would get the starry night if I had to buy another one.I love the seatbelt option though never used.Cons:Zipper is great quality, too bad it's not two sided zipper like the smaller sack.The only time we use a lighter weight sleep sack is on the days in spring and fall where it's too warm for a heavy sack but not hot enough to use AC.Overall amazing buy, keep up the good work woolino!

This is by far the best one I found. We moved from Canada to Europe and then to Asia and it is so good that it was suitable in all places.My cheeky second boy was able to wear it and learn to climb out of his crib. He also managed to navigate stairs while wearing it - it was so durable, built to last for sure! You may want to get two for when those diapers can’t hold all that night pee and it needs a wash!

We love the Woolino sleep sacks! I discovered them with my first, and have continued to use them with our second. I love how easy they are to wash and dry, how well they hold up after many, many washes, they’re easy to get on & off, even when your child is sleeping, they are warm enough in the winter, and not too warm in the summer, & they are soft and cozy. My kids have loved using them, and we have used both the sleeping bag style, and the style with legs.

I purchased the 2T-4T size for my 14 month old in the interest of extending its usefulness, and while it does look huge on her, it's been working out just fine with no modifications. I might add snaps under the arms because the openings are so wide, but right now I've been putting her to bed wearing a T-shirt to avoid a draft, and that's been working out just fine. The openings aren't big enough to go over her head.This sleep sack is very good quality, and my baby is very comfortable in it. The fabric feels smooth and heavy, but she does not get sweaty when she's wearing it the way she does when she wears her (lighter weight) fleece sleep sacks. She does not get up as quickly when she wakes up from her naps or in the morning, so she falls back asleep more often, and even when she doesn't fall back asleep she lays down in her crib playing or chatting happily for longer where before she used to stand right up and start trying to get our attention.The only thing I don't love is the zipper, it zips from under the right arm all the way around to the bottom left corner of the sleep sack. So unless you want to shimmy your baby in from the top without unzipping it, you have to open the entire thing. I prefer the style of zipper used on the Halo sleepsack where the zipper is straight down the middle, that way you can get your squirmy baby in the arms before zipping them up.

Our little guy has been using a Woolino sleep sack since he was 6 months old. I had a few Halo sacks and put off buying the Woolino because of the price. The Halo cotton sleep sacks were okay, but I really hated the sweaty, syrupy-smelling fleece sacks. I also hated having to constantly buy bigger Halo sacks every time I turned around. So after a month of pining for the Woolino, I broke down and bought it. A year later, I wish I hadn’t wasted my money on the Halo sacks.Inside and out, the sack is superb. It is so soft and the inner core of wool gives it a nicely weighted drape. It has quickly become our favorite --- so much so that if it gets soiled overnight, we make sure it is washed and dried by bedtime. (We only have one - but it is machine washable.)By the time our long and lean son was 14 months old, it was clear we needed a new Woolino with more length. Hooray for the size 2-4 years! While it looks ludicrously long on him now, it doesn’t overwhelm him. He can move about in his crib with ease and never be without a blanket. In the winter, he wears long pajamas under his Woolino never wakes up cold. (We don’t let his room get below 67 degrees.) In the summer, he keeps the Woolino but wears it with shorty pajamas underneath. Even when his west-facing room occasionally gets too warm, a balmy 77 degrees, he seems cool as a cucumber, never sweating in his sleep.If you are on the fence about purchasing this sleep sack… don’t fret a moment longer. Simply buy it and know you won’t regret it. It seems extravagant, but you can get by with only one, and it will quickly be your favorite too.

These are my favourite sleep sack of all. I have researched so much about other brands such as merino etc and tried a few but still went back to these sleep bag. It is pricey compare to the most sleep sack on the market but worth every penny. You don't need to wash it so often since it is wool and is naturally antimicrobial. I have one for two years and my son used to wear it when he was only 4 months, he still use it and the size still good enough for him, however I have ordered one size larger too since he will outgrown it very soon. I do recommend purchasing two so you don't need to wait for laundry time etc when one is dirty.I have used it in high humidity, hot weather, cold weather, camping at winter etc and they are absolutely fine. There is a temp guide indicator card which is included in every package and shows you what is the temperature now and tells you what you should wear underneath this sleep sack for this temp. I did follow that guide and I was happy. they are snapped on the top and a zipper goes all around. The underarm snaps allows it to be fitted on younger babies and I don't use it now. You don't need to remove the sleep sack when using carseat since it can pass through the fabric and perfectly buckled. The waist is not too loose or too tight compare to most brands that I used such as Merino, Halo or Grobag. It is perfectly tailored. It is not so thick but so warm. In summer time I put on a very thin layer underneath and he is not overheating at all. In winter depends on the weather I need a long sleeve bodysuit under or pajamas(like for camping).Strongly recommend it.

Mio figlio ha sempre dormito nel sacco nanna, dal suo primo inverno.Per lui, che si muove molto di notte, è la soluzione migliore, perché rimane sempre coperto e non prende freddo.Il sacco che aveva in precedenza prevedeva che indossasse solamente una maglietta sopra l’intimo. Questo sacco nanna, invece, per la temperatura di casa nostra, sui 20 gradi, prevede l’utilizzo del pigiama a maniche lunghe.I primi tempi dopo il cambio dal sacco nanna precedente (del tipo classico, di cotone con imbottitura), mio figlio aveva freddo e dovevo lasciargli le calze e aggiungergli una coperta leggera. Ora lo indossa senza calze e la copertina non serve più. Non so se questo sia dovuto ad un rialzo della temperatura in casa o all’abitudine, vedremo cosa succederà il prossimo inverno!Per il resto, ritengo che sia di ottima fattura e mio figlio lo indossa volentieri, fa parte del suo rituale per la nanna.Ero indecisa se acquistare il modello con i “piediâ€, ma poi ho deciso di seguire i consigli di alcune delle recensioni, che dicevano che i bimbi riescono comunque a camminare con il sacco “chiuso†ed effettivamente è così!È di dimensioni generose, quindi credo che lo potrà utilizzare ancora per molto tempo.Da tenere presente la gestione del lavaggio: dato che ha la lana il produttore consiglia il ciclo delicati con centrifuga blanda, che lascia il sacco molto bagnato, il che richiede tempi di asciugatura lunghi e in orizzontale. Sempre secondo le raccomandazioni del produttore, può essere asciugato asciugatrice con il ciclo “senza caloreâ€, che, ignoranza mia, non ho mai sentito nominare e che la mia asciugatrice non ha.Nel complesso abbastanza soddisfatta. Per il secondo sacco nanna, devo ancora decidere se acquistare un Woolino, oppure un sacco nanna classico.

I was unsure about buying this product because of the price really.. I have purchased similar items in the past when my child was a baby and he used to find them too hot and didn't like his feet covered. However, for the past year (he is almost 4) he has been waking up in the night because he has kicked off his blanket.. prior to this he had not slept through the night for 2.5 years... So when he slept through it was amazing..to then revert back was really tough.. in a desperate attempt to find a solution I purchased bigger blankets, hooks to tie the duvet to the bed, wrapping the covers and he still kicked them all off and I ended up putting him in bed with me..which helped him, but I still woke up several times to cover him up and then he sleeps sideways, I get kicked.. you get the picture.. with hesitation I went for this sleep bag - I did show my son and asked whether he wanted the feet out or in and let him choose the colour. I can not tell you how pleased I am, he loves it and just sleeps for hours and hours.. 12 hours.. I'll have to see how it goes as it gets colder but I am pretty amazed considering previous attempts.. I just need to work on having him fall asleep back in his own bed!!
