## Description

desertcart.com: Unnivoll Baby Sleep Sack 6-12 Months 3 Pack 100% Cotton Lightweight 0.5 TOG Wearable Blanket Baby Sleep Bag with 2-Way Zipper for Newborn Infant Blue : Baby

Review: 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.
Review: 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
*by J***Y on July 30, 2025*

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.
