Great sleep sak
This sleep sack rivals all those expensive ones. Not only is it cute but it’s very soft and warm. Perfect weight that breathable for those cold night. Great quality and looks like new after several washings. Must purchase several!!!

The BEST Sleepsack by a Hardcore Critic!
I’m typically pretty hard on baby products as far as critiques. Especially things I’ve purchased on Amazon because you can’t see or feel them in person. HOWEVER! This sleep sack is simply amazing! We live in mid-Michigan where the temps have gotten down to -10 at night. But even on a typical winter night where it is in the 20’s or teens, it gets down to 65° in our house. She has slept SO soundly with this sleep sack because she’s stayed nice and warm. The sleep sack itself is BUTTERY SOFT ORGANIC COTTON!!! I’m fairly certain the inner lining is cotton as well. It’s definitely filled with fluffy, plush, comfy polyester. The zippers are good quality and strong, never get stuck or caught. Overall, FIVE stars!! (My sister just had a baby a few days ago and I even bought one for my new nephew so he can wear it this coming fall/winter) Super soft, super warm and thick, great quality! If you live where it’s cold, don’t hesitate. Look no further! This is an amazing sleep sack!

Thick, cozy sleepsack
I love how thick and cozy this cotton sleepsack is. Perfect for winter. The material is soft, and ours haven’t clumped up after washing. I also love the double zipper for easy diaper changes or just to crack open for extra breathability on warmer nights.

Warm like a comforter, safe sleep, easy diaper changes
These are a bit flat right out of the package, but once you wash it puffs up a bit and is almost like a thin comforter for your little one. Keeps them nice and warm/toasty while allowing for safe hands free sleep for when they start to move/roll around at night. Definitely recommend for colder climates. Plus easy diaper changes without disturbing your sleeping baby.

Fluffy, soft, and warm!
Really nice material, its light and fluffy - seems warm tools! It does shrink a bit in the wash/dryer. Zipper design makes it easier to take on and off during those middle of the night diaper changes!

The Best Sleep Sack for Growing Babies!
We LOVE our Mosebears Sleep Sacks! As our little chunk outgrew his swaddles and needed free arms, as well as some more leg room, we looked all over to find a great transition sleep sack. Once we started using our first Mosebears, we knew we'd found the right one! What's been great is that they're: 1) SUPER soft, like ridiculously so. I wish they came in adult sizes. And 2) they flare out so there's plenty of legroom. And finally, 3) because of the extra weight and impaired mobility, it really helps our little guy sleep better. We got the first one when little man was just over 9 months old, and was really running out of room in his old sleep sack. For the first several weeks, he couldn't even sit up in it (which was great). Now, at just over a year, he can definitely sit, and even stand up in them (he's standing/cruising during the day, but is not a walker). So, it's definitely possible for them to move around in the crib, and even fall over if they're super active. But it's cozy enough, and just bulky/weighty enough that it slows him down and encourages him to sleep in a way that pajamas alone definitely don't! Anyway, we ordered our second one 2 weeks after the first, and we don't put him down without it!

True to size. Thick warm sleep sacks
Love it my daughter fits so well into it. This is the second time we bout one the first one was 12-18 moth now we have 18-24. It’s thick and nice and warm. Honestly you should make more sizes my son in 2T and 3T and not a lot of people sell sleep sacks his size. He should be using a blanket but he kicks them off at night. If yall make a size bigger in the future I’ll definitely purchase again.

Perfectly cozy
These are great sleepsacks. They're so cozy and soft and warm. Our room usually sits between 17 and 19 degrees and with a footed cotton sleeper my baby seems very cozy. They wash and dry very well, no twisting or shrinking, zipper doesn't catch. This is the second one I've purchased and I'll be buying more.

Muy recomendable
Me encantó llegó muy sellado, al lavarlo no sentí que ocurriera alguna malformación del material, lo que sí es que sentí que este modelo viene muy grande para que lo consideren por si lo requieren solo para el momento, en mi caso aunque fue grande considero que me va a servir para mucho tiempo más, es muy calientito y suavecito

Amazing quality! Thick, warm and soft
This sleep sack is so cozy I wish I could sleep in it! It's thick like a comforter, and both inside and outside it is SO SOFT! Could be coincidence, but my baby has been sleeping way better since using this. Amazing quality, I absolutely love it, will be buying many more
