The best sleep sacks!!
This is now the 3rd time I’ve bought these sleep sacks! Every time my son grows out of them I buy the next size up. They are such good quality and so soft! Easy to clean, cute designs, lightweight and thin, and having double zippers (that actually WORK) makes it so easy. He sleeps so well in them, and seems so comfy. The fold over mittens come in handy because he has an NG tube and he used to pull it out at night and he doesn’t anymore, it’s so hard to find sleep sacks in larger sizes with them. If you’re looking for a good quality sleep sack this is the one. They’re easily worth the money. 10000% recommend!!

Sleep sacks
Ordered these sleep sacks for my 5mth old as something that can be used year around and love them already. The fabric is soft and breathable & isn’t too thin so perfect for a mild spring- fall night. Haven’t used it during the winter yet but I imagine I can easily put a long sleeve onesie under (instead of a short sleeve onesie) for really cold nights as our room can get a bit drafty.I appreciate the 2 way zippers and both sleep sacks had good seams and functional zippers. Additionally, the designs are the cutest. I washed it prior to using it and had no problem with shrinking. I expect to be able to use it for a long time as it seems pretty durable.

Good quality & replaced our Swaddle
We were ready to transition our little one out of a swaddle and into a sleep sack. My little one loves to be warm, so I wanted a sleep sack with sleeves which aren’t as popular as the sleeveless one. I have a bigger baby. My LO is almost 4 months old and in the 80-90 percentile in weight and height since birth. I’m glad I read the reviews and went with the Small anyway. It fits just fine with some room to grow, which is awesome. It is very comfortable. The patterns and colors are cute. I love that they have mittens option on the sleeves.

Best sleep sacks for cooler bedrooms
These were perfect for my second child. I wish I had known about these with my first. These helped my infant feel snuggly and warmer in the WI her season. Her bedroom stays cooler than the rest of our home and I didn’t have to worry about her being cold. They have been washed lots and still look new. No zipper issues and good color choices.

My daughter loves them
My daughter has worn these sleep sacks since she was about 4 months old. We’ve come back and bought the next size up every time and now she’s almost 2 and still sleeps in them. She loves it and calls it her “seep sack”. Soft, keeps her warm, and I love that it has the two-way zipper for diaper changes.

Great but runs large
l wanted something that could still fold over and cover my babies hands so he didn’t scratch himself when he was transferring from swaddles to sleep sacks, however i did have to end up waiting a little bit to wear them due to the size. I will say, like most of the other reviews say, these do run very large. My baby, who is average size, is now 9 months old and still fits perfectly in the 0-6m and probably will for another 2 months. Attached is an image of my baby at 6.5 months and you can still see that the sleeves are very long. He has been wearing them since 5 months so i would say they are more of a 4/5m-10m size lol. Anyway, they are soft and comfortable and i do really like them now!

Great buy
Love these for my 6 month old. We keep our house cold, so we got the the fleece ones and it works great. Don’t have to worry about a blanket going over his face or him not being covered and getting cold. They are very soft and cozy. Definitely recommend. Will probably try the cotton ones as well.

Muy buena calidad, si muy grueso ni muy delgado. Los cierres funcionan muy bien

Perfectos para noches de 20-23 grados C en conjunto con pijama con piecito. Super suaves y cómodos para bebé.

-Calientitos para el LEVE frÃo de la madrugada. -Mi bebé lo ha utilizado por 3 meses y aún le queda mucho espacio en las piernitas.-Por tener doble cierre, los cambios de pañal son súper sencillos.-Si ocurren accidentes, la tela exterior aguanta muchÃsimo y casi no deja pasar nada a la sábana o el colchón.
