Es wonderful
Yesaida A.
I love the product but it’s too small for my baby I guess he’s a big boy and I was ok with the item at first but now it really too small
Ruben A.
My soon is just getting out of swaddle and this one was really great. He sleeps so many hours even without moving himself, very relaxing and the most amazing dream ever hehe. I would highly recommend it because it is warm (i got the winter one) and my heater is at 71.6 F, and we just use a single soft sheet around his feets.
I am buying the 6-15 months as it was a great purchase for us.

The best sack by far! My baby loves it and sleeps 10 hours.
Thouraya A.
My baby loves this sleeping bag❤️he enjoys sleeping time . I got the quilted 2.5 and wanna get a new one as well.
Isadora F.
The winter sack is the most needed for the season!!! Baby loved it!!!
Brittany G.
Seems very warm and well made. I do wish it was a little longer, my 3month old is already hitting the bottom with her feet.
Katie E.
I have used nested bean sleep sacks on both my children now. Swear by them!
Jamie B.
Love this sleep sack so much. A friend gave me one as a gift and I had to order two more. My son loves these sleep sacks and he is so cozy and warm at night. It was the perfect transition from swaddling too- we started using these at around 2 months and haven’t stopped since (our son is almost 6 months old now). Couldn’t recommend highly enough!! I’m now about to buy another one for a friend who is expecting….
Emilie B.
Awesome sleep sack! Still struggling with night sleep but does help. We got the winter one and it definitely keeps him warm!
Jesse J.
We just moved to this one from he new born zen one. I love this sleeper! It’s a must have! She sleeps all night!
Lizeth L.
My son sleeps through the night! We love Nested bean
Bethany W.
Nice and warm. Weighted spot seems to help keep my child asleep. Only thing is with the big size (15-24) it’s difficult to zip a wiggly child into. The zipper is on the side and it’s quite long so it’s lots of material to deal with. But it does the job well!
Brooke H.
Baby loves his sleep sack! Immediately got more sleep between the 12am-5am hours, when he used to wake up from being too cold. So glad to have this to keep our baby warm this winter.
Peggy J.
It is a gift for my grandson for Christmas so I don’t know what it’s like yet. But I’m sure he’ll like it. At least I hope so.
Barbara M.
Excellent
Maria R.
My 4 month old went from sleeping 4-5 hours restlessly to sleeping a full 8 soundly on the first night! Happy baby and happy Mama!
Lovely T.
My lil one been sleeping more than she normally does
Mikayla C.
My one month old can only be swaddled for so long. She loves her hands near her face. This sleep sack was super helpful for both me and her. She stays warm and asleep.
Amanda D.
Love it!! This is our fourth nested bean weighted sleep sack for our baby - it’s a MUST have for great sleep! We started with the 0-6 mos size and it made a huge difference in her sleep. Then when she was ready for the next size we got two bc we love them so much and always need to make sure we have one available (between spit up’s and daycare etc). Then when the weather changed this fall we invested in a winter weight one and she loves it too! She is 9 months old and has been sleeping 10-11 hrs straight each night since about 4/5 months old with with sleep sack! Expensive but worth it.
Taylor L.
This is perfect for keeping our little one warm and snuggly for a full nights sleep!
Yarely A.
I love how thick and warm it is..
Alexandria W.
The material is really soft and comfortable. I also really like that it washes well.
Emily P.
She “sleeps like a baby” should with room to grow.
Erica F.
Amazing and safe product!
Nicole P.
Their winter zen sack is the best!
Mackenzie R.
Nice sleep sack. Heavy for the cooler temps!
Winnie N.
We had the Classic sleep sack so we had to get the winter blanket for the cold months ahead
Leslie C.
Baby slept so well on night two in the nestedbean sleep sack. She’s 4months old and is only waking once in the night to feed. I can tell she is getting a better, deeper sleep weary by the sleep sack. Going to buy another when she outgrows her current one.
Breanna P.
The winter weighted sleep sack has helped so much for our little guy to sleep thru the night! Highly recommend
Heather B.
I wish you had a bigger one. My babe is tall and will outgrow this soon. She actually sleeps in this!!
Taylor R.
Only sleep sack my baby would sleep in after transitioning from Merlin’s magic sleep suit!
Alexandra S.
Loved it
Monica G.
We have thoroughly enjoyed this zen sack! My girl goes to sleep so quickly and is content throughout the night. And, I am so assured that she is cozy and warm. I was thrilled to see this winter option because it can be so stressful to think about how to ensure warmth overnight!
Brianna F.
This is the first sleep sack I’ve gotten for my kids that’s considered “winter” and isn’t just fleece and fleece can be so hot. This sleep sack seems like a little comforter for your baby and looks SO cozy and is super soft. I love the weight distribution for the 15-24 month. It was definitely a little heavy overall for my son on the first night but after that he adjusted and sleeps well with it now. Definitely a high quality product for sure.
Alison S.
We love our nested bean. My guy sleeps so well in it and stays warm. My only complaint is that it seemed to shrink quite a bit after washing and probably won’t last much longer. I bought a medium, he is 5 months, but I should have maybe ordered the large.
Cathy K.
So cozy for the winter months!
Tammy H.
Great quality!
Donna H.
We have tried this multiple times and so far are not seeing any different results. In fact my son has slept worse.
Josefina J.
We love our sleep sacks! Our now 6 month old has been sleeping 8+ hours at night since using them! We will definitely continue to use with him and our future babies!
Breanna G.
My daughter was up 4-6 times a night. After 2 nights in this, she finally slept through the night and has since. I forgot what sleep felt like, no joke.
Shahad J.
Love this one
Shahad J.
Love this sack, nice warm and soft
Jessica R.
Love this sleep bag ! The shipping however was VERY long. I waited about a month just to receive it
Patricia L.
My new Nephew will be snug as a bug in this. He will be born late fall so this will be perfect.
Samantha G.
This was perfect for the few cold winter months in our home. We found baby’s room got the coldest and we needed the winter sack after using the classic for a few months. I found it quite a bit warmer and thicker than the classic. Baby’s legs and body were always warm and body heat was kept in the winter sack. It was just what we needed!
Paige C.
Baby slept comfy and cozy all winter!
Joanne D.
Fantastic for restless toddlers!
Christine O.
Sydney LOVES this sleep sack. We got the winter one, because i wanted something a little thicker (even tho it is spring time) our house tends to be cold. It is super functional between the shoulder snaps and the bottom zipper up the side.
Monica H.
She loves it . I lay her down awake give her the paci and in 10 minutes she’s asleep.
Esmerelda L.
Soft and warm, and calming for my little one. I recommend it to every new parent I know! Love it!
Dariela S.
Very good, I love it ❤️
Anastasia Z.
Didn’t work for my child
Rebecca P.
It’s a nicely made sleep sack, but unfortunately it made no difference in our little girls sleep pattern
Denise D.
I have ordered a total of 7 assorted sacks. We love them all and send one to daycare . It’s part of her sleep training.
Christina N.
At first transitioning my 4 month out of swaddling into a sleep sack was hard. Starling reflexes took awhile to go away. It did take some time for my little one to adjust to this sleep sack. When she did get use to i, I use it every single night. It’s probably top 5 best investments I made for my infant! Considering purchasing another one!
Haikuhy K.
I love these sleep sacks! Especially this winter version. My son kept waking up in the middle of the night because he was cold and once I switched over to the winter sack he sleeps soundly again! Highly recommend
Elizabeth P.
I love this sleep sack and plan on buying another one. My babe is 7 weeks old and was waking every 2 hours. By night 3 of wearing this sleep sack she was sleeping 4-5 hour stretches! I was skeptical but it works!!
Joanna L.
We like this sleep sack. The fabric is soft and smooth and a nice weight and overall much nicer than other brands. I also like the blue color a lot. Our baby moves a lot in her sleep and I think the egg must be a tad uncomfortable when she sleeps on it but it is hard to tell since she's a baby.
Karen J.
This is the best sack for our baby. She loves it and allow her to move when she sleeps
Brandy S.
I really love this! I feel as though it has made falling back to sleep much easier for my baby. The fabric is very thick and warm, perfect for the winter time.
Delta P.
Very easy to use! A little snug around the arms but doesn’t seem to bother baby.
Allyson T.
Love nested bean!
Morgan S.
We love the winter sleep sack! Stays warm and cozy all night!
Tiffany J.
Works great!! My daughter loves and has been sleeping through the night with this sack
Allyson T.
Love nested bean!
Danielle M.
I love the thickness of this sack. We use it with a bamboo bodysuit and it’s been perfect. So snuggly !
Kristy S.
My daughter refused to sleep anywhere other than on our chests. If we put her down, she would only sleep 30minutes max. We tried every sleep sack and swaddle. Nothing helped until we tried nestedbean. Now she sleeps in her own bed for 3-4 hour increments.
Stacy F.
Love how warm and cozy they are! Wish there were more options in colors- the white stains easily
Katelyn S.
Bought this for my grandson. My daughter says he sleeps better when he wears it!
Rosa A.
I had try the swaddle before but did not work for us. Then i return it and got this one and my baby loves it! He has been sleeping through the night (started by waking up 2 times instead of 3 times). My baby is 6 months old. Thank you , can't wait to buy more later ! Highly recommended! Try it and find the one that works for you guys
Hossien K.
Great for the colder months!
Trisha L.
We absolutely love this! Thick and warm, perfect for layering during the cold months. Incredibly easy to put on and easy access diaper changes. I’ll be getting many more of these.
Whitley D.
He sleeps 7 to 7. Amazing!! We love all of the sacks, but our favorite is defiantly the winter one.
Megan M.
Since using our nested bean, our little one has been able to sleep 4-5 hours overnight! She used to be so restless and hasn’t been able to be swaddled with her arms in since about 2 weeks old! We’re all sleeping a bit easier thanks to this sleep sack!
Miriam H.
My baby loves it!!
Rebecca G.
We love the nested bean products
Alina H.
Absolutely love everything from this company.
Kristin P.
I have a 5 month old who has had a hard time getting longer stretches of sleep at night despite some well researched, logical approaches (routine during the day, increasing daytime feeds, sleep cues, etc...). I didn't expect a new sleep sack to be a miracle fix, but I did hope that maybe it would improve things a little. Overall, it is a well made, warm, sleep sack. But it definitely has not made any difference at all in my baby's sleep. And because of this, it was not worth the high price. But I am happy for those who have found it helpful!
Amber A.
Great quality, comfy and thick perfect for colder nights. As far as my child sleeping better I have not seen any changes in the past month with the sleep sack. It is my favorite sack to wear on my son though, my other sleep sacks are not as good quality.
Rebecca S.
This works really well for our daughter. She knows when she gets in her sack it’s bedtime. This is a must for our bedtime routine.
Angela K.
My grandson loves his sleep sack!!!!
Sarah P.
Baby likes it. It’s warm which is also great but I feel like it’s a little short to fit size 15 month
Britnii D.
Absolutely love this product! Definitely going to buy more, has helped my daughter sleep for 8-10 hours a night!
Vanessa P.
Love it! Baby sleep better since we got it!!!
Lisa S.
My 4 month old started rolling but is still learning, so at night he would roll on his belly then wake him screaming. The only things that has stopped him from going completely on his belly is this sleep sack! It has given me and my baby more than 2 hours of sleep again! The bags under my eyes thank you, nested bean!!!
Lauren S.
We love this sleep sack! The weighted penguin is a life saver and helps so much. We chose the winter one because we keep our home pretty cool and she hasn’t woke up sweaty or too hot at all even having a full fleece footie pajama on too! Amazing!
Elizabeth P.
The sleep sack is lovely and snuggly for my little one and I like the simple white design. Unfortunately her sleep has been no better when wearing it but at least she is cosy and warm!
Natalia F.
I found this sleep sack with my second. He is a lot more challenged with sleep than my first, I think this cozy sleep sack helps us just a bit more. I would recommend the thicker sack for a new born. We skipped swaddling and went straight to this.
Laura S.
Noticed a difference in sleep by night 2 - he is now sleeping most of the night :)
Lily S.
We love the bean sacks for our little baby bean. She had a regular weight and winter weight one in the 0-6 size but was starting to out grow them, so we got the next sizes up and they are still great. They are soft and warm and the little bean weight seems to help (and we have tried other sacks).
Nilam R.
We absolutely love this winter sleep sack! My son looks comfy, warm, and has been sleeping peacefully through the night!
Logan K.
My baby sleeps like an angel in this sleep sack. It has been a great transition from the swaddle
Kristina N.
I love this, my baby was already a great sleeper, but I was looking for a safe way to keep her warm and the winter weight cotton is wonderful.
Alyson W.
We love the 2.5 tog sack! Gives her the perfect amount of warmth without over heating and without the use of the blanket! I purchased a second one to switch out when one needs to be washed. I wish they made them for adults cause the fabric is so soft and comfy!
Linda H.
This was bought as a gift, Therefore I do not have the info to share.
At the time I purchased it, I indicated it was a gift. I know they were happy to receive it, and tried it, however from what was shared, I do not believe it made a difference.
Kaleb A.
My daughter had just became 4 months old in late December and a week or so goes by to where she had started waking up constantly throughout the night. Every so often my wife would nurse her back to sleep depending on how long ago she was nursed prior. Other times, I’d have to rock her back to sleep. Even these methods would work occasionally they wouldn’t thanks to her sleep regression. Bought the winter Zen Sack, put her to bed and she’s finally getting back to her normal 8-10hr stretches of sleep. Highly recommend! Don’t buy off Amazon - could have knock off items compared to the original manufacturer.
Robin N.
LOVE THIS! MY BABY SLEEPS COMFORTABLY AND HAD A SOLID NIGHT SLEEP!
Sarah D.
Wonderful! My son had trouble sleeping through the night so we got him the Zen Winter Sleep Sack and he’s slept through the night ever since, the whole family appreciates it! Nested Bean for the win!

The sleep sack is lovely and snuggly for my little one and I like the simple white design. Unfortunately her sleep has been no better when wearing it but at least she is cosy and warm!

I found this sleep sack with my second. He is a lot more challenged with sleep than my first, I think this cozy sleep sack helps us just a bit more. I would recommend the thicker sack for a new born. We skipped swaddling and went straight to this.

We love the bean sacks for our little baby bean. She had a regular weight and winter weight one in the 0-6 size but was starting to out grow them, so we got the next sizes up and they are still great. They are soft and warm and the little bean weight seems to help (and we have tried other sacks).

My baby sleeps like an angel in this sleep sack. It has been a great transition from the swaddle

I love this, my baby was already a great sleeper, but I was looking for a safe way to keep her warm and the winter weight cotton is wonderful.

We love the 2.5 tog sack! Gives her the perfect amount of warmth without over heating and without the use of the blanket! I purchased a second one to switch out when one needs to be washed. I wish they made them for adults cause the fabric is so soft and comfy!

This was bought as a gift, Therefore I do not have the info to share.
At the time I purchased it, I indicated it was a gift. I know they were happy to receive it, and tried it, however from what was shared, I do not believe it made a difference.

My daughter had just became 4 months old in late December and a week or so goes by to where she had started waking up constantly throughout the night. Every so often my wife would nurse her back to sleep depending on how long ago she was nursed prior. Other times, I’d have to rock her back to sleep. Even these methods would work occasionally they wouldn’t thanks to her sleep regression. Bought the winter Zen Sack, put her to bed and she’s finally getting back to her normal 8-10hr stretches of sleep. Highly recommend! Don’t buy off Amazon - could have knock off items compared to the original manufacturer.
