Absolutely adorable
We love this sleep sack! The material is incredibly soft and the quality is excellent. The stitching feels durable and well-made, and the zipper is smooth and easy to use for nighttime diaper changes. The fabric weight is perfect not too heavy but still warm enough. We keep our house around 68°F and layered over footed pajamas it keeps our baby perfectly cozy all night. The design is also so cute and looks just like the photos. Overall this sleep sack feels high quality, comfortable, and thoughtfully made. Definitely one of our favorite sleep sacks we’ve tried!

Soft and warm; great quality
I’m really happy with this sleep sack. The material feels soft and comfortable, and it seems warm without being too heavy. The two-way zipper makes diaper changes easier at night. My baby sleeps well in it and we’ve used it every day since it arrived. It also washes well and hasn’t lost shape or softness. A great basic sleep sack that does exactly what we needed.

Soft, well made, and very comfortable sleep sack
This is a really great sleep sack. We had a different brand before, so I took my time choosing a new one and I’m glad I went with this. The quality is excellent. The fabric is 100% cotton inside and out, very soft and comfortable, while still being warm enough. The stitching is neat and well done throughout. The print is beautiful and looks very gentle in real life. The zipper works smoothly, and I really like that it opens from both directions, which makes it much more convenient. I got size 18–24 months for my 17-month-old daughter. There is a little room to grow, and it fits nicely. We’ve already washed it a couple of times, and it still looks great. Definitely recommend.

Great sleep sack at a great price
I've purchased cotton sleep sacks from Amazon that seemed great, but shrunk 2 sizes in the dryer. Purchased yet another and the neck and arm holes were huge. Unsafe huge. I bought these as a last attempt before I went with a big known brand and I'm really glad I did. No massive arm and leg holes, great length, double zipper, and soft material. They did shrink in the dryer, but not too terribly. You can always hang dry them. Will purchase again!

Cute and simple sleep sack!
Very cute sleep sack and the designs are lovely. The fabric is soft and thin, but it doesn't feel cheap - it can provide some warmth.If your baby needs something thicker or warmer, I would get a different sleep sack. My baby is a little over 2 feet and fits well with room to spare so they can stretch out their legs. The zippers are decent and I don't have any issues with them getting stuck.

Good for Summer or Spring
Good quality and comfortable to wear for summer. Not appropriate for winter weather or room temperature less than 70 degrees. True to size and Price is good too.

My baby loves these
My baby loves these sleep sacks. Lightweight and love how the zipper goes from top to bottom and a second one from bottom to top. Makes it easy to change a diaper in the middle of the night. We have had this size since my baby was 4 months and now is 8 months and fits the best now. It seems to keep him warm through the night and during nap time. It’s soft and cozy. Washes well. We will definitely keep getting more of these. My baby sleeps so good in them.

No fue exactamente lo que yo quería. Me di cuenta que necesitaba unos mas calientitos. Pero estos serian buenos si hace un poco de calor donde duerme tu bebe. La material es muy suave y me gustan los patrones de la tela. El cierre que se puede abrir por los dos lados tambien es util para cambiar pañales.
