## Description

desertcart.com: Unnivoll Baby Sleep Sack 18-24 Months 100% Cotton Long Sleeve Wearable Blanket Baby Sleep Bag with 2-Way Zipper 2 Pack 0.5 Tog Sleeping Sack for Newborn Infant : Baby

Review: Great Sleep Sack - I ordered these sleeps sacks for my son's sleep study as a two way zipper was required. The quality of these sleep sacks is great with a super soft and comfortable material, lightweight for warmer months, and great zipper quality. The color in person are slightly darker than the pictures shown, however the style is adorable. The sleep sacks have now been worn and washed a few times, and hold up great! Defiantly good value for money.
Review: Great sleep sack for babies that run warm. - My daughter loves her sleep sacks, but she runs warm/hot, so I am transitioning her clothing/sheets to as much cotton as possible. The material is a light enough for it to be breathable, yet warm enough to soothe her. It has a double zipper that makes changing her diaper convenient and the mitten cuffs are easy to fold over. I washed it in a delicate cycle and tumble dried it. It was still damp when it was done, but it air dried well when I hung it up for the night and was able to put it on her this morning. Sizing was interesting. She is currently 26" long and ~13lb, putting her in-between the small (0-6 months) and the medium (6-12months). I ordered the medium first, and it was way too big. The small fits her just right and has plenty of room to spare. I would not recommend this for a newborn as it would be way too big. Overall, I think this is worth the price and she seems to be sleeping in it well. If something changes I will update my review.

### ⭐⭐⭐⭐⭐ Sleep sack with sleeves LOVE!
*by N***Z on May 22, 2024*

Cute print and well made cotton outfit. I love the long sleeves and mitten hands! Material is soft and a good weight to be warm without being too much bulk. Washes easily and the zipper makes diaper changes hassle free. Runs big but that’s ok will get lots of use out of it.
