Cozy and warm
I’m absolutely loving this baby sleep sack! It’s super cozy, incredibly soft, and very warm – perfect for the chilly winter months. The 100% cotton fabric is gentle on my little one’s skin, and the 2-way zipper makes it easy to get them in and out. The quilted design adds an extra layer of warmth and comfort. Highly recommend this sleep sack for any parent looking to keep their baby warm and snug during the winter!
Perfect
Have only been using this sleep sack for about a week now but I’m super happy with it! I ended up purchasing a second one just a couple days after the first one arrived. The fabric is so soft, the stitching is good quality, the 2-way zipper is smooth and strong. It’s the proper TOG for fall/winter weather here in Alberta. Comfortable, safe, and warm for my little guy! He is already sleeping better at night with this on. Highly recommend.
Great quality
Really great quality, but it shrinks a lot upon washing. Bought 0-6m for my 2m old and his feet are just at the end now with no further room to grow, and heâs an average sized baby. I also noticed his hands get quite cold so I have taken to adding layers for him. He seems quite content to wear it and sleeps well(for a newborn/young infant). I think itâs worth the cost, just ensure your baby is warm enough and remember to size up.
Perfect for Canada weather!
Size: I bought Large for my 5 month old baby. He is 97 percentile for height and weight, I wanted to make sure that he has lots of leg room. I was worried that the sack would be too large on the chest that would roll up to his face but it didnât, the sizing was perfect. Iâd recommend buying as per your babyâs height plus 7-10cm so they have room to kick and move around. I already bought XL as well so he can wear them when large is too tight in coming months.Quality: It feels so soft, has perfect thickness, warmth and shape. My baby has been rolling, crawling in it in his crib, it still maintains the shape which is important as it prevents his limbs getting caught.My baby sleeps longer in it, he is so happy when he wears for every nap/sleep. His room is between 19-21 Celsius and he wears long sleeve bodysuit without socks. I highly recommend this product. I can see the usage from October to May in the Alberta weather.
Super good quality
Very warm and of very good quality, baby loves it
Size up!
I have a 6-12 month sleep sack that my 14 month old is just growing out of so I ordered a 12-18 and itâs the same size .. so basically too small now. Seems to be really warm though and soft but like still go up a size
Not 100% cotton
This is a good product, but I was a little sad to see that the lining is 100% polyester, and just the outer material is cotton. Perhaps I mis-read the description when I bought it. If you want your baby in 100% cotton, keep looking.
Great quality
Very thick and soft, baby loves it!
The sleep sack is perfect for these cold winter nights, I do not allow my baby to sleep with a blanket so keeping him warm can be difficult without a good sleep sack. This one is really great I like the thoughtful design with the double zippers and it keeps him warm and safe all night
This baby sleep sack is warm and cozy for the infants like my sisterâs new born. Itâs perfect for winter to keep her baby warm.The 100% cotton fabric is soft and gentle on the babyâs skin and wrap her up perfectly and stably. The 2-way zipper is super convenient for diaper changes quickly or taking it off quickly.Just wish it was a little thicker then it would be more perfect
This sleep sack is definitely thick and warm for winter. It fits my 2 year old well. Because of the filling and the material it does feel kind of bulky and restrictive. Iâll probably only use it for really cold nights.
The Unnivoll Baby Sleep Sack 6-12 Months TOG 2.5 Winter Baby Wearable Blanket is currently my favorite sleep sack as we approach colder weather. Its basically a wearable quilt. Its also a little more spacious than some of the others, so I sometimes layer it with an additional, smaller fleece sleep sack for extra warmth. I highly recommend this product to anyone looking to keep the baby warm.
I took off one star because it is smaller than I would like. I have a very tiny 10-month old, and she basically out-grew this already. The material is very soft, and warm, and I do love that aspect. I just wish it were a little bit longer. Other sleep sacks I have for the 6-12 month range are much larger. I suggest sizing up if you go with this.
