Winter weight TOG 2.5 Top reviews from the United States Like sleeping on Clouds This was the end of my very long search for a REAL winter sleep sack. Our house is old and very drafty so my baby would wake up cold.. not to mention she was very spoiled from hanging out on mommy & daddies comfy bed. Expecting her to sleep through the night on that hard as rock baby crib mattress was a joke. I bought all the big brand sacks that claimed to be "for winter" and they were literally a piece of cloth... When I bought this one I was soooo happy. Not only is the material very soft it's also very blanket/comforter like to the point I can be comfortable/confident with laying my baby in it with just a shirt and diaper on knowing she will be warm all night! She started sleeping through the night! I recommend this sleep sack to all my friends and family! She's 1 1/2 now and in the large size
