Great sleeping bag! Solves all of the my “is he too hot/too cold” problems!
LOVE this sleeping bag! I’m all for Merino clothing for myself, but I had no idea they made a sleeping bag out of it until I came across woolino. All of my questions have been answered:”Is he too hot, too cold, should I use full length pyjamas, a diaper shirt, or something else?””What TOG is good for this season? What about in between seasons?””His room is warm in the evening when he goes to sleep but then it’s so cool in the morning because the open windows/AC kicks in, what if he gets too cool at night?”My son is 20 months old and this bag is AWESOME. Since getting this bag, I have snuck into his room a few times to check whether he’s too hot/too cold, and he’s always been just right. We live in a place where it’s 22C one day, and 2C the next with snow. This bag is good for all of those days!I think this bag is a no brainer. It does cost more than most, but it’s worth it. I wish I had found Woolino sooner!
Best sack we have
We have tried many sacks! This has a nice weight to it. It’s very soft, lightly layered This sack is rated 17 – 24C (Tog 0.7 on the lower end) but it’s much too warm for a 24C room (19C max high temp of room). If you live in a warmer climate, this isn’t the sack for you unless you live with A/C. This is a beautifully made garment, well worth the cost for us.
Best sleepsack that grows with my kid
Love the wool. Keeps my baby warm so that i dont need to worry. Comes with a cardboard thermometer that tells u what the baby should wear.
Excellent quality! Two considerations.
This sleep sack is very high quality. I had purchased several different Sacks and this one is the nicest! The zipper is excellent and I like that it goes around the sides of the sack rather than up the middle bc I find thatâs more comfortable for my baby. I only have two complaints:One is that because itâs so long my baby (6 months old) sometimes gets it twisted and wrapped around his body (it does not effect his safety in any way he is an excellent mover/roller)The second is that bc itâs wool, when it gets wet it has a weird smell… kind of smells like a barn or petting zoo when my baby chews and drools on the collar when teethingThe material is super soft and it is breathable so itâs great for all seasons. I feel this sleep sack will last us for the year!
Best natural fabric.
This sleep sack is a must. It’s soft, natural and made with a high quality zipper. The price is steep so i recommended getting a size bigger so you can get more use out of it. Worth every penny.
Best sleep sacks
I bought this size because my daughter outgrew the smaller one. My 2 year old wears this every night and I don’t have to worry about her being too cold. I check the guide and dress her accordingly and she’s set for the night. She loves the pattern as well. The only thing is that it takes awhile to dry after you wash it.. but then again you don’t need to wash too often since it is pure wool. Great product, would definitely recommend for infants and toddlers.
Woolino is the best!
Weâve used Woolino sleepsacks exclusively with our daughter since she was a few months old. They are the best! The quality is amazing and you never need to worry if your little one is too warm or too cold. She outgrew the 2-24 month size so we have now moved into this size, which is just as amazing as the others. You wonât regret your purchase.
Not warm enough for Canada
For $100 this sleep sack SHOULD keep my baby warm during the winter. I live in Canada so I was willing to spend the money to ensure my baby stayed cozy and warm. We keep his room at 70 degrees Fahrenheit the entire night, so it’s not even that cold in his room. I gave the Woolino a fair shot for a week. He was waking up an extra time at night than before wearing the Woolino, and every time he woke up he felt cold. The back of his neck was also cool to the touch. The Woolino did NOT keep him warm. Since this was my main reason for buying, I returned it. However I have listed several other pros and cons below.Pros:Very soft and comfortableAll naturalCons:Not warm enoughRequires special wool wash detergent, and can only be air dryed
Really nice sleeping bag, the fabric feels really nice and it fits my 8 week old very well.
I cannot rate or praise this sleep bag enough. So much so … I have bought another x3! One at the same size for my newborn (0-6 months), which he has been using since he was 1 week old.Whilst it is costly, it is worth the investment. It takes a massive weight off one as a new parent worrying about what tog. This is for all seasons. It comes with a handy thermometer which a guide re what clothes little one should wear underneath. The upfront cost will save purchasing several bags of different togs. So a saving in the long run.
Weich, warm, flexibel: mein Sohn macht darin immer seinen Mittagsschlaf, er schläft sehr gut darin und fühlt sich nie “gefangen”… Hinzu kommt, dass ich ihn viel seltener waschen muss als andere Schlafsäcke… Tolles Material, das man In vielen Fällen einfach nur auslüften kann.
Babt sleeps like a dream in it
Me ha encantado. Viene en una cajita muy mona donde te explica todos los beneficios de la lana merina (viene en inglés) aún no lo he usado pero se ve de buena calidad .Edito : después de usarla 10 dÃas le han salido pelotillas por dentro, y al lavarla sale con un olor raro, no se si será del material o de que.La parte positiva es que he observado una ligera mejora del sueño de mi bebé, la toma de las 4 am la hace a las 6 am. Veremos si es casualidad o se debe al saquito.Por otro lado yo he comprado el de 6 a 18 meses y mi bebe tiene 3 y medio, le va bien ( es un bebé con percentil 40)
