Review: Cozy and soft - Great sleep sack, runs a little large but that’s better than running too small. And at first I thought it was too big to where she couldn’t wear it yet, but when I put it on her it wasn’t too bad. Good quality, nice cotton. I ended up ordering another pair cause my daughter wears them for her naps too. I didn’t notice shrinkage when washing them. They feel very soft, the colors are pretty and I haven’t found my baby sweating while she sleeps like she used to prior to these sleep sacks. They are not super thin and not too thick either. We live in Texas and keep our AC running all day. Her room tends to stay at 72-74 degrees and she wear her normal clothes underneath during her naps and at night she has a long sleeve/legs onesie underneath her sleep sack.
Review: Good sleep sack - Good quality, perfect thickness for summer time and it should work year round just by adding clothes to baby. Soft. They run a tad large though so keep that in mind. I like that it’s slightly big so baby will be able to use it longer. Definitely recommend. Good quality for the price

## Features

- Cotton

- Premium Fabric: Considering your baby's delicate skin, this sleep sack is made with pure breathable, soft cotton. We use a pre-shrinking process to minimize fabric shrinkage, so that the sleep sack for 0-3 and 3-6 months could stay cozy, warm, and soft after every wash.

Let your baby move freely with the mittens folded down during playtime, or flip them up on cooler nights for extra warmth. The cover helps prevent your baby from scrathcing and keep your little one cozy without restricting their tiny hands.

The thoughtful design is benefit for baby's healthy growth by minimizing sleep disturbance. Besides, our premium zippers won’t snag or get stuck, so you can avoid those frustrating mid-night struggles.
- Four Sizes: With a roomy design, this sleepsack provides your baby more convenience for standing, crawling, playing or sitting, etc. With 4 sizes, it provides a lot room for baby's growth. It’s wonderful for newborns up to toddlers over 2 years old.

### ⭐⭐⭐⭐⭐ Our daughter loves her dino jammies!
*by C***A on August 14, 2026*

Runs a bit large- she typically wears 12-18m clothing and this is a good fit. Soft and similar thickness to a nice t shirt, weight is appropriate for daytime naps and summer nighttime
