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.

Great Quality!
These sleep sacks are great! The zipper works well and they are roomy. They are great for babies or toddlers that should not have blankets with them yet. They kept my baby nice and comfortable. I loved all the colors as well.

Breathable, soft, and perfect for warm nights
I ordered the Unnivoll sleep sack in the 6â12â¯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 babyâs skin. I was reassured to learn it has a 0.5â¯TOG rating, making it ideal for room temperatures around 75â80°F and summer nights.The twoâway zipper is a gameâchanger 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 preâwashed 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.

Great Halo Dupe
These sleep sacks are quite similar to the Halo ones but you get 3 for the price of 1! The fabric is comfortable and seems thick but not hot. The length is true to size and fits our 5 month old perfectly with room to grow. The patterns are very cute and the two way zipper makes changing easy! My baby seems to sleep really well in them so far.

Great sleep sacks; cautious of zippers
Soft and lightweight sleep sack perfect for spring and summer. Only complaint is that the zippers don’t feel like the best quality, so i am cautious when using to not break them. But overall not too bad given the price for 3!
