Must buy (:
My daughter, at 6 months of age still was not sleeping through the night, she always seemed cold and somewhat restless. I purchased these sleep sacks and the first night putting her in them, she slept 12 hours!!! She is now 8 months old and is still on average sleeping about 12 hours at night when wearing her sleep sack. These sleep sacks are warm and comfortable for my sweet girl, are soft to the touch, fit well and so far have been able to stand many of washes- great quality!

Amazing
This sleep sack is perfect for colder weather! It’s cozy and warm, but not too warm! I especially like that I don’t have to layer up in the sleep sack, which makes it harder at night when having to change the diaper! It’s super soft and cozy, too. My husband even said “I wish I had one for myself”. I love the ease of the zipper and temperature sticker is super helpful. Amazing quality, perfect thickness and it’s the perfect length for my baby to grow into.

Can comfortably set night temperature lower.
Before our little one arrived, we always slept best at a cool 65°F. Once the baby was born, we bumped the heat up to 70–72°F to keep them warm, but the dry air led to restless nights for us adults.This sleep sack has been a game-changer for our toddler. The material is cozy, and the temperature-sensing fabric gives me such peace of mind knowing they’re comfortable. We’ve finally been able to drop the thermostat back to 66°F, and now the whole family is sleeping soundly. While it’s a bit of an investment, the quality and the savings on our heating bill make it well worth the price.

Coziest Sleep Sack We Own!
The coziest, softest, and most luxurious sleep sack that we own! I am beyond impressed by both the feel and quality of this- I am completely blown away! I also feel incredibly at ease by the temperature gauge along the zipper. No more wondering if baby is too hot or too cold at night! Absolutely worth the money. I would say it runs on the larger size- my guy is four months and wearing a 0-6 month sleep sack. I rolled the sleeves and it seems to help 🙂 I was also impressed by the packaging!! Very clean and neat!

Unisex sleeping bag for babies and toddlers review
We loveee this sleep sack for camping! I was really nervous about taking my infant out camping in the PNW because it gets pretty cold at night. It kept her warm the whole night, and it’s well worth the money. It’s easy to wash and dry, and the style is really cute. The thing I most appreciated was the temperature gauge just inside the zipper, that gave me the most peace of mind. She was not quite 1 year when we used this a couple of times. It fits well with room to grow!

Warm but slight defect in filling color
Love these sleepsacks but I washed this the first time before using and the color of the wool bled and now there’s a stain on the front. It was definitely from the sack as no other items in the wash have this. Reached out to merchant for a resolution. Its very warm otherwise and perfect for winter nights.

Cute and durable.
I really want to give this sleeper a five stars because it’s so perfect for winter. However, I kept noticing cotton all over my baby’s feet in the morning whenever he’s wearing this sleeper. The length and thickness were great for my 7 months old baby though.
