This product is perfect!
This product is such great quality! Itâs lightweight but also still acts like the wearable blanket itâs supposed to be so itâs still warm and not see through at all. It had the double zipper for easy access to that dirty diaper while your little one is sleeping. Not to mention the super cute prints the sleep sacks come in. Definitely recommend for you toddler or baby especially in the warm seasons! Your baby will be sleeping soundly in this soft sleep sack!

Super soft and perfect for Toddlers
I bought these in the largest size for my 3 year old who wasnât ready to have just a blanket yet, and they worked great as they are longer than a lot of other options! Very soft and cute prints too, and wash very well.

Perfect Sleep Sack
Our 8 month old boy LOVES his sleep sack, he doesnât get a good night sleep without it. He is a chunk weighing at 28lbs at 8 months and is also very tall. It fits perfectly with room to grow but not loose where itâs dangerous. I love the two way zip for night time diaper changes. I wash it very frequently, and its quality is still outstanding. Itâs on the thinner side so I layer accordingly.

Comfortable sleepwear
I had previously purchased the lightweight cotton Elys and Co. sleep sacks for my baby, but needed a larger size than what they offered. While this sleep sack isnât as thick, it is made with equally high quality cotton. It is perfect for the summer months when not as many layers are necessary.I also like the zipper on this sleep sack better than the other brand because it is stronger. Since there are two zippers on this design and my baby has figured out how to unzip them, I did have to sew down the bottom one to keep her from unzipping it.

Exactly what i needed
Easy to use, so soft, not too thick, its bigger than i expect but good for growth and the zipper has a cover over it so it wont hurt your baby.

Runs small
I purchased this sleep sack for my 3 month old at the time. She is in the 50th percentile for height and weight so sheâs not a particularly large baby- but I found the small size to be too small for her. She should have been well within the limit for at least 1-2 months longer and it already got a bit too snug. I went up to the next size and that suited her much better. If you have a baby on the upper end of their weight recommendations and want this to last for a bit- consider going up a size. Other than that- this are thin, very lightweight and perfect for the socal summer nights,

Must know how to sew! EDITED!
Edit to add:The seller contacted me and apologized for how the sleep sacks arrived. They sent new ones, which arrived about 2 days after they first contacted me. The new ones appear to be in great condition! No loose threads, no zipper issues! Great customer service and attention to their product.**The only reason I had not reached out to the seller myself was because the only return option that Amazon offered was if I returned the sleep sacks in their original packaging to a drop point. Since I had already washed and fixed the sleep sacks, I no longer had the original packaging. No other options were offered by Amazon and so I (wrongly) assumed that I had no other options.Very thankful the seller reached out and fixed the issue!Original post:The blue one came basically unfinished with strings hanging out all over the top of the zipper area and the zipper cover itself. Currently, it all appears still attached, but there are some loose threads. So I imagine I’ll have to fix the zipper cover portion in the near future.The white base with dinosaurs appeared to be intact. However, when I washed it (as I do with all fabric that is going to touch my child’s skin) the top of the zipper came completely away from the hem of the sleep sack. I did a gentle wash cycle and low heat tumble, per the tags instructions. So that I will have to fix before it can be used.I do appreciate that the tag is on the outside of the sleep sack, so it can’t irritate.I do not appreciate having to finish the sleep sacks myself.
