The quality is great and it's pretty stretchy. I'm able to put my son in pajamas and the sleep sack without worrying if he'll be too warm. I also love how it has hand covers, my son soothes himself to sleep by rubbing his head and the covers prevent him from scratching himself. The only downside I found is the sleepsack seems to run big. My son is 6m,19lbs and 29in I ordered the 6-12m. I recommend this and in my opinion it was worth the money.

I think some people writing these reviews don’t understand how sleep sacks work. They are supposed to be a little bit big and not be snug. They are supposed to be able to move a bit in the sleep sack. Think of it as a blanket. Would you want to be held still under your blanket? No. Neither does your baby. This is meant for them to still be able to sit in, crawl, roll, etc.This sleep sack is amazing and I highly recommend it to everyone. I’ve even let my friends use it for a night or two to test it before they bought it. My girl is warm and cozy in it. I bought this when she was 6 months old and she is now 8 months and we still love them. The zippers are good and it DOES NOT shrink in the wash. The little mitts don’t stay over the hands but outside of that it’s great!

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.

Love the weight of these and that they are cotton. Easy to do diaper change. The hands don’t stay completely covered but it was a good transition for him. Also had to put a bandaid on the bottom zipper pull because it kept clicking against the crib slats while he rolled around.

Nice fabric, strong Zipper. Don't worry if they look like they would fit a two of your children inside because it shrinks a lot after the first wash lol. The ratio of arm length to sleep sack length is a little off meaning the arms are big but other than that these are a great deal

These sleepers arrived and they look great. We haven't used them yet but they seem warm and soft.

Sleep sacks are fine & just right for our purposes but the arms are so long. The 24 month was comically huge for my 12-month-old who wears size 18 month clothing otherwise. I exchanged the 24 for 12-18 and the sleeves are still long to hat we need to roll them up.

Nice material but sizing is terrible. I ordered a medium for my child baby based on size and when it came it was WAY too big so reordered the small and it was the EXACT same size as the medium when I held them up next to each other and so my baby can't wear these until he is much larger.
