Great quality, comfy!
Cute design, and so soft! Lots of room to kick, but snug enough that it doesn’t ride up. Perfect thickness for warmer nights. My little boy sleeps really well in these (as well as a 5 month old is able to sleep)!

Great sleeper sacks
These are not only adorable patterns but lightweight and breathable which is perfect for the warmer summer nights. They fit my little man perfectly, and he seems to like them and sleeps very comfortably in them. I absolutely love the double zipper so if I need to change him at night I don’t have to completely unzip him. Another feature I love as well is that it zips from bottom to top so I don’t ever have to try to get the zipper started and have to try getting it to hook with my squirmy little guy who’s always trying to get away and be on the move (moms I’m sure you know what I mean). I would definitely recommend and purchase again

Wearable Blanket
I absolutely love these! They are so great and light in the warmer months, but keep baby nice and cozy. I don’t have to worry about my daughter overheating, and love all of the options and colors. My daughter has been using these from 6-12 months and now I bought more for 12-18 months. I am not comfortable with giving her a blanket, so this is a safe way to keep her warm at night! Highly recommend.

Breathable, soft, and perfect for warm nights
I ordered the Unnivoll sleep sack in the 6–12 month size and was pleasantly surprised by how light it feels while still maintaining a secure fit. The fabric is pure combed cotton and noticeably soft against the baby’s skin. I was reassured to learn it has a 0.5 TOG rating, making it ideal for room temperatures around 75–80°F and summer nights.The two‑way zipper is a game‑changer during diaper changes. I was able to access without fully unwrapping the sleep sack and waking up the baby. A zipper guard at the top effectively prevents scratching the chin or neck. I also appreciate that the fabric is pre‑washed and shrinks very little even after repeated washes at low heat.The design is roomy around the hips to support healthy movement while still keeping the upper body snug. My baby seemed more comfortable and slept more soundly compared to swaddle blankets. After weeks of use, the sleep sack looks almost as crisp as day one and remains breathable even on hot evenings.

Cute and comfortable
My son loves these. Soft, comfortable, he can easily crawl and walk in them. Cute designs. Fits him well. Perfect to wear all year round. Keeps him warm, even on -40° nights.

Wonderful sleep sacks!
I bought these sleep sacks for my now 9 month old son. I waited until I had them for a month to write a review. I have had zero issues with them. The zippers are great, they hold up in the washer and dryer, and the colors stay vibrant! The only problem there has been was they did shrink 1 1/2 to 2 inches after being washed and dried. See pictures. This wasn’t a problem for me because I have a little guy. For reference he is 9 months old, just now getting into 6/9 month clothing, he is 18.4 pounds and 21 1/2 inches long. I bought the 6/12 month sacks. They are pretty big on him but not to where they are a safety hazard. He absolutely loves them and uses them every night! They are a bit on the thinner side which I prefer. We live in Texas and it is super hot right now. He sleeps in these and a onesie with the AC on, and he is very comfortable. I highly recommend these sleep sacks for the quality and price!

Quality fabric and great design
We use a short or long sleeve onesie under these depending on temp and to keep the zipper from rubbing against the belly. These are soft, not too thick or thin in my opinion and pair well with onesies. They wash well and retain shape, have had no issues with zippers. I have bought multiple sizes, always good results. They also zip from each side, which is great for diapers changes, just unzip the bottom portion.

Nice sleep sack, crazy shrinkage
I have liked these so much I’ve gotten 2 sizes so my son can keep wearing them. I dropped a star because it should be known that these shrink severely the first use and are really a basically a size smaller than they say. My son (normal size baby) moved into the 6-12 month sleep sack at 3 months old. I didn’t realize how much the first set shrank before they were used so I was in for a surprise when the 6-12 month sacks arrived looking enormous. Lucky for me they shrank right down to the size we needed and have been working for a couple months. Nice and soft and pretty light which was nice for summer.
