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.
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!
Lindsay B.
I LOVE the winter Zen Sack. Our house gets pretty cold in the evening and it helps keep our little one warm and snuggled up. I love how thick and soft it is. Very comfy for our little girl.
Zorangel N.
I bought it for my daughter. I tried a classic swaddle but she doesn't like it, good customer service by the way. then, I got this one. She slept better but a little more problem with acid reflux
Laura L.
This product is great quality! I love the new way this is weighted. My daughter seems to enjoy it better!
Daniel R.
It definitely makes a difference! She goes to sleep much quicker than without it and it it keeps her warm!
Dacota C.
Our little man falls asleep faster and stays asleep longer with the winter zen sack! He couldn’t sleep without it!
Bridgette R.
Our sweet girl was waking several times through the night. Took a chance on Nested Bean and we haven’t looked back. She is now sleeping through the night every night and taking naps during the day, all while in her Nested Bean sack.
Justin w.
I absolutely love our nested bean! Baby sleeps SOOOO GOOD now!
Andrea B.
Oh wow. For weeks I have been enduring my daughter waking up every 60-90 minutes during the 4 month sleep regression. Last night I put her in this sleep sack for the first time. And she actually slept. She slept 9 hours in a row. 9 hours. In. A. Row. This sleepsack is life changing.
Donna A.
My son sleeps so well in this sack. We are so grateful!
Emily R.
I like the design and seems well-made, but unfortunately my daughter does not like it at all for night sleep (had TERRIBLE night of sleep that improved when went back to other style sleep sack - tried twice to make sure wasn't coincidence, and happened again). Daycare isn't allowed to use weighted sacks for naps, so it is not going to get used at all. I wish I hadn't washed/labeled both sacks before trying the first one and realizing it wouldn't work. I would've returned the unused one.
Monica R.
The winter sleep sack is truly like a sleeping bag. I was expecting more of a micro-fleece material. The material is nice but not what i expected. These sleep sacks are difficult for me to get on my incredibly active son. I don’t feel like the weighted option has made much of a difference in his sleeping habits either, unfortunately. I’m not sure I would spend as much money again, I would likely opt for a less pricey brand. I wish these would have worked for us. I would have bought stock if they improved our sleep!
Michelle S.
Now that it’s winter I noticed my son was chilly at night. Now since putting him in this he does wiggle around as much in the night. This weighted blanket is such a game changer, we love it!!
Becca S.
Our little guy loves his sleepsack. The Winter version is so nice because it keeps him warm. He sleeps for so much longer when he naps in this
Kayla H.
We have used the sleep sack for our first but now with our second, she is a stomach sleeper and this option was perfect. It is soft and seems very comfortable.
Florence A.
Nicely made. Thick, soft and cozy. My baby loves her sleep sack.
JORDAN S.
We started using the Zen Sack when we transitioned our two-month-old out of her swaddle and she has been sleeping in it every sense! The winter one keeps her nice and warm and she has been sleeping 6-8 hours stretches while it's on.
Ashley L.
I love how soft and plush this sleep sack is. My son also loves his new sleep sack. Definitely helps keep him warmer as well.
Melissa C.
We purchased the winter cotton a month ago and loved it so much purchased a second! It should be all season cotton because our little guy will use this all seasons! It is so comfy and soft I wish I had one for myself. Worth every penny!
Arianna L.
So far my baby is sleeping an extra two hours at night. I’ll take it!
Michelle P.
I accidentally bought purple thinking I had ordered gray. Their customer service was outstanding and sent me an exchange that day! It was my first time purchasing the thicker/winter sleep sac. Needless to say our transition from swaddle to arms out has been so easy! We love nested bean products! HIGHLY recommend to anyone with littles
Krista H.
Very nice material and nicely made! Live in southern Indiana where it’s usually colder here( cold weather coming) but afraid my 3 month old is too hot natured for it. Debated for a while on the winter or the cotton version…. The winter is definitely nice and cozy ❤️
Garland D.
We introduced the Zen Sack to our three month old and he started sleeping through the night immediately! He falls sleep quicker and gets more restful sleep. Will definitely be ordering more and recommending. 10/10!
Amanda L.
My babe didn’t like swaddles from pretty early on so we switched to the regular nested bean around 2 months. Now she’s 7 months and it’s winter and pretty cold. She loves the winter bean! It’s cozy like a comforter and she can still move around and kick her legs in it. We bought 2. These are our favorite sleep sacks by far.
Sara F.
Wonderful
Getsy C.
I've ordered from Nested Bean ever since I came across their ads. I have almost every item from their store but my favourites are the Zen sacks! This particular Winter Zen sack has a very soothing colour and keeps my son warm especially at night! I'm glad I got another colour too. Keep up the great word, Nested Bean :)
From a very satisfied mom of 1 :)
Makala J.
My son’s room always gets a bit colder than the rest of the house, and this blanket is the perfect weight. I rest a bit easier knowing he’s cozy and warm. He also sleeps really well in his nested bean sack. When I transitioned him out of the swaddle into this we only had about one night of fussing before he got used to it. Now, he loves having his arms free so he can stretch them out in all directions!
Linda T.
We bought this to help with the 4 month sleep regression our daughter is having. It hasn't helped at all so far but we are hopefully that once we get past this phase she will be able to sleep longer at night. Overall its a great product for what it is. we bought the winter version and keeps baby warm and toasty when its cold.
April U.
At first we were unsure if it was actually working but it was cold and I was glad baby had a safe way to keep warm anyway. Fast forward a couple weeks and it was laundry night and baby didn’t have a clean sleep sack to sleep in. We put her down without any sack and she woke up every 30-45 minutes. We finally realized it was likely due to her missing her sack! Once dry we put it on her during one of her wakings and she was out for the night!
Kathryn B.
We have used nested since my daughter was a newborn!! She loves it and sleeps like a champ! She is almost 2 and we still use it! I love the comforter one for winter!!!
Yvette S.
Great comfy fabric. Worth the money.
Rosie S.
My 5 week old baby is a Goliath and as much as I like the sleep sack, I mistakenly bought the 0-6 month zen sack assuming it would be appropriate. It will fit him for a pretty short period of time considering how the arm holes currently fit. He did sleep better the first night, had a rough night the second night and is doing pretty well thereafter. I may purchase more in the next size. Please advertise to check weights and length of infant as I assumed up to 6 months would fit a 5 week old longer than this will.
Stephanie P.
Fits great. Warm but not to heavy. The weighted tummy helps. My son is sleeping better and warm now that it’s winter
Kayla M.
Love this sleep sack for colder nights
Grace N.
Love the winter weight!
Chaya D.
Love the material and my daughter is sleeping beautifully since we got it.
Zoe M.
I’m in love with this new winter version! It helps keep my baby nice and warm & she sleeps a much longer stretch now!
Jessica H.
My daughter has been using the 0.5 TOG Zen Sleep Sack since she was 4 months old and we’ve loved it. Now that we’re in Winter (Coastal California) we realized the 0.5 was not cutting it at night. When this Winter one came it was so thick I was worried it would get her too hot at night. To my surprise it keeps her nice and warm, but not over heated. She’s been sleeping harder and falling asleep easier. Would definitely buy again!
Nicole M.
My 12 weeknight of loves the winter sleep sack! Whenever we put it on she starts going sleepy and knows it’s time for bed! She’s been sleeping 6-7 hour stretches with it!
Kelly V.
Our little guy seems so cozy in this!
Tiffany C.
This is perfect for winter. My baby transitioned to the crib and his room gets a little chilly at night. I can rest well knowing that this sleep blanket will not only keep him warm but give him comfort due to the weighted chest. He has been safely using it to sleep for a month. I'm not sure how he would sleep without it but I'm not willing to try it out. It has survived several washes already and the quality is great. I'd buy another one in a heartbeat.
Brittany B.
I had high hopes for this sleep sack, and was hoping it would solve all our sleep problems but, alas, it has not. It’s well made and warm (our bedroom where our son sleeps is a little chilly, so I do love this sleep sack for that reason), but I don’t think the weighted aspect does anything to make him sleep sooner or longer. He still cries every time we put him in it (like he did the others) so, at least in our experience, the beads don’t magically make him calm down or anything. He also isn’t sleeping longer or shorter in it — just about the same as the other sleep sacks. Like I said, it’s well made and warm but if you’re looking for a magic elixir, this isn’t it… at least it wasn’t for us.
Patricia P.
We love it
Sarah S.
Worked for better sleep for a few days now shes back to every 4 hours
Gabriela G.
Keeps my son warm at night and he sleeps longer when he wears it!!
Yoshee K.
This thing is like voodoo magic!! Lol
Samantha S.
I loved this when it arrived, soft and warm. However, I followed the washing instructions, I even washed on the hand wash cycle , and air dried in the dryer. It still got mis-shaped and seemed to have shrunk a tad. It also had a small hole by the seam, not sure if it was there beforehand. My 3 month old will only be able to wear this 3-5 more times, wish I had gotten the larger size.
Maureen S.
Great product ! It does promote warmth and helps baby sleep !
Emily L.
My kids loves it. It is so soft.
Nora
Nice product. Fabric is thick and soft.
Jacquelyn R.
My baby sleeps so much better with his nested bean on! Game changer!
Stefanie B.
Winter ones are amazing! Sooo thick! I didn’t expect them to be this thick so I ordered one in every color! Love them!
Stefanie B.
Our daughter will fall asleep in about 5 min max for her naps with her sleep sack on! Will not nap without it!!
Felicia R.
It is really well made and a is super comfy cozy for my baby. As he is a side sleeper the weighted chest doesn’t always work but I know he is warm and snug in it!
Hayley J.
My baby sleeps so much better with the sleep sack! 10/10 would recommend
Jessica S.
My baby LOVED IT! She sleeps longer!!
She would not sleep throughout the night without waking and now she sleeps through the entire night. 100% recommended!!! Don’t waste money on other sacks :)
Lyndsey P.
My son has sleep more then 8 hours each night with his sleep sack. I absolutely love this!
Erica B.
Material is super soft and the zipper is high quality. We love Nested Bean! Our daughter is in the largest size and our son in the smallest.
Courtney S.
Love Nested Bean! It’s so soft, easy to wash, and my son loves the comfort of the weight on his back (since he’s a tummy sleeper)!
Cynthia T.
My baby loves the nested bean sleep sack. We got the winter sack in addition to the regular ones, and it keeps our baby warm and cozy at night. Can’t recommend it enough!!!
Sarah S.
The winter sleep sacks are so thick and warm. I don’t worry about our little one being cold at night as the weather changes. I highly recommend!
Yulia A.
My baby loves it, he knows that it is time to go to bed when this sack is on him
Sasha T.
Amazing. Kid loves it. Highly recommend!
Amanda G.
My daughter outgrew her other sack, so had to get another one. She loves to be really warm and this one fits the bill.
RAyna K.
She immediately started sleeping better through the night!!! My 6 month old just needed that weight. So glad I made the purchase.
Laura L.
So great! Baby girl slept so great the first night we used it!
Whitney S.
So soft and cozy and I love the dark dusty blue color! Very happy with my purchase.
Andrea H.
Love this sleepsack! Have it in each size and almost every weight - heavy weight is perfect for winter!
Alexis R.
My son has used nested bean swaddles since 3 months old. I just bought the winter sleep sack and I’m obsessed!! It is sooo soft and I love that they have neutral colors. It keeps him soo warm! Definitely will buy again.
Angela F.
My 2 year old has had this for over a year now and we love it
Shannon H.
Listen...I was skeptical but let me tell you, this works! The first night my 6 month old son used this, he slept from 8:30 p.m. to 4:46 a.m. My husband and I were shocked! Although he hasn't slept this long since, we have been getting 5 to 6 hour stretches in the last week or so since we have been using this...so now he only wakes once at night for a feeding. I will be ordering more. Trust me, just try it. Nothing to lose, but a wealth of sleep and comfort to gain for you and baby.
Jenny D.
Super soft and a nice thicker feel. Temperatures have cooled but this really seems to help keep my little one warmer at night. Love this style blanket and arrived fast. I am happy with my nested bean blankets and wish I had purchased these for my first child. Will definitely recommend these wearable blankets to others.
Allison H.
Great quality, warm, cute, and works well. My baby went from waking 5-6 times each night to 2.
Calen P.
I have used the regular sleep sack and it helped my baby sleep some, but I just purchased the winter sleep sack and the first night using it my 5 month old slept 8 1/2 hours straight!
ashley W.
My son sleeps in this most nights. Sadly, it hasn’t extended his sleep any. Still only about 3 hours at a time, but this keeps him warm and has established a bit of a night time routine for him. When it goes on, it’s time to sleep. We will definitely be getting the next size up when it’s time!
Diane D.
The nested bean sleep sack is a MUST! Our son slept through the night at 2 months old. It’s seriously such an amazing purchase. Highly highly recommend!
Laura S.
3 months old and it gets chilly in the baby’s room. This sleep sack keeps her snuggly warm and she seems to appreciate the weight on her chest. She starts getting sleepy eyes as soon as we lay her down and snap on the shoulders.
Rachel L.
Love this thing! I won't make any miracle claims about all my babies sleep problems being solved, but I will say I have been sleeping a lot better knowing my baby is nice and warm without being tangled in blankets from rolling around in his crib.
My baby like to roll from his back to tummy and "gets stuck" and will start to cry. I have been placing him on his back (per usual) in his new sleep sack and while he still rolls from side to side, he is definitely less inclined to make full rolls during bed time. He just tends to hang out on his back until he falls now. I love it so far.
Laura M.
Super comfortable and warm for my little one as the season changes. Nested bean has become our most preferred sleep sack.
Carol B.
My new great grandson and his mom love the Zen sleep sack. The baby is sleeping much better which makes everyone happy.
Hillary P.
Must buy!!! I mean it, my baby was a good sleeper before I bought this, she would wake up once a night but after a few nights of using it she sleeps through the night!! I couldn’t be more happy. I love it so much I’d like to buy another one. Makes me sleep better too knowing she is staying warm as well
Kendall H.
Our little guy was doing consistent 11-12 hour sleeps through the night until one day he just...wasn't. We thought we had made it through the 4 month sleep regression because this didn't kick up until right at 4.5-5 months. After weeks of adjusting wake windows, trying to improve naps for better night sleep, doing larger feedings, etc we wondered if he could be cold and also having a hard time getting himself back to sleep after jerking awake several times.
The first night with the Nested Bean winter (TOG 2.5) Sack, we saw an improvement of about an hour of total night sleep. We haven't unfortunately seen consistent improvement in night sleep duration but what we have seen is a reduction in the amount of times he's fully waking up (and then crying) between sleep cycles throughout the night. Which is a help! I wish it had helped his overall duration of night sleep but I'll take less crying any day!
Rebecca G.
We love this product!
Nichole C.
All babies are different, with that we haven’t seen a HUGE difference in sleep. Some nights are better than others. Overall, I think this will work better each night.
Johnny R.
Love it!! Free one please
Johnny R.
Love it please a free one!!!
Cloe U.
My daughter didn't seem to mind it does keep her nice and warm.
Jenna Z.
My only regret is not getting this sooner. My five month old would not nap anywhere but in my arms and at night would wake up every 45 minutes to an hour wanting held, after a week in the sleep sack she sleeps ~4hrs at a time at night waking only to eat, and is napping in her bassinet like a pro.
Joanna C.
This is SO COZY! Usually my baby wakes up with cold toes even though the room isn't all that cold. With the winter sack, she's been sleeping more sounding and with her toes all nice and warm. We've been using the Nest Bean since 2 months and we haven't dared to swap her out of it.
Johana B.
Love it
Rachel B.
Bought this as a baby shower gift for my newest granddaughter, so it has not yet been tried. Can't wait to see her in it when she's born!!
Grace V.
I gave it as a gift.
Kristin H.
So warm and so soft! My little guy loves it and I feel better knowing he is warm at night when our house is cold!
Alicia V.
My baby loves her Nested Bean sleep sacks!
Kisha D.
My 6 month old went from waking every 2 hours at night to waking once a night since wearing his sleep sac! Definitely recommend
Robyn G.
We love our next bean, I wish we could buy a bunch more! My daughter only wakes once or twice per night and goes back to sleep, allowing me to get some rest myself. The sack is soft and warm and I can be sure that she is comfortable when she sleeps!
Victoria C.
Too small . Baby is average 13m old and can hardly fit in it. Too expensive to order another. If it fitted well it would be perfect they're lovely and soft and the soft weight is great

It’s well made and warm (our bedroom where our son sleeps is a little chilly, so I do love this sleep sack for that reason), but I don’t think the weighted aspect does anything to make him sleep sooner or longer. He still cries every time we put him in it (like he did the others) so, at least in our experience, the beads don’t magically make him calm down or anything. He also isn’t sleeping longer or shorter in it — just about the same as the other sleep sacks. Like I said, it’s well made and warm but if you’re looking for a magic elixir, this isn’t it… at least it wasn’t for us.

I loved this when it arrived, soft and warm. However, I followed the washing instructions, I even washed on the hand wash cycle , and air dried in the dryer. It still got mis-shaped and seemed to have shrunk a tad. It also had a small hole by the seam, not sure if it was there beforehand. My 3 month old will only be able to wear this 3-5 more times, wish I had gotten the larger size.

My baby sleeps so much better with his nested bean on! Game changer!
Stefanie B.
Winter ones are amazing! Sooo thick! I didn’t expect them to be this thick so I ordered one in every color! Love them!
Stefanie B.
Our daughter will fall asleep in about 5 min max for her naps with her sleep sack on! Will not nap without it!!
Felicia R.
It is really well made and a is super comfy cozy for my baby. As he is a side sleeper the weighted chest doesn’t always work but I know he is warm and snug in it!
Hayley J.
My baby sleeps so much better with the sleep sack! 10/10 would recommend
Jessica S.
My baby LOVED IT! She sleeps longer!!
She would not sleep throughout the night without waking and now she sleeps through the entire night. 100% recommended!!! Don’t waste money on other sacks :)
Lyndsey P.
My son has sleep more then 8 hours each night with his sleep sack. I absolutely love this!
Erica B.
Material is super soft and the zipper is high quality. We love Nested Bean! Our daughter is in the largest size and our son in the smallest.
Courtney S.
Love Nested Bean! It’s so soft, easy to wash, and my son loves the comfort of the weight on his back (since he’s a tummy sleeper)!
Cynthia T.
My baby loves the nested bean sleep sack. We got the winter sack in addition to the regular ones, and it keeps our baby warm and cozy at night. Can’t recommend it enough!!!
Sarah S.
The winter sleep sacks are so thick and warm. I don’t worry about our little one being cold at night as the weather changes. I highly recommend!
Yulia A.
My baby loves it, he knows that it is time to go to bed when this sack is on him
Sasha T.
Amazing. Kid loves it. Highly recommend!
Amanda G.
My daughter outgrew her other sack, so had to get another one. She loves to be really warm and this one fits the bill.
RAyna K.
She immediately started sleeping better through the night!!! My 6 month old just needed that weight. So glad I made the purchase.
Laura L.
So great! Baby girl slept so great the first night we used it!
Whitney S.
So soft and cozy and I love the dark dusty blue color! Very happy with my purchase.
Andrea H.
Love this sleepsack! Have it in each size and almost every weight - heavy weight is perfect for winter!
Alexis R.
My son has used nested bean swaddles since 3 months old. I just bought the winter sleep sack and I’m obsessed!! It is sooo soft and I love that they have neutral colors. It keeps him soo warm! Definitely will buy again.
Angela F.
My 2 year old has had this for over a year now and we love it
Shannon H.
Listen...I was skeptical but let me tell you, this works! The first night my 6 month old son used this, he slept from 8:30 p.m. to 4:46 a.m. My husband and I were shocked! Although he hasn't slept this long since, we have been getting 5 to 6 hour stretches in the last week or so since we have been using this...so now he only wakes once at night for a feeding. I will be ordering more. Trust me, just try it. Nothing to lose, but a wealth of sleep and comfort to gain for you and baby.
Jenny D.
Super soft and a nice thicker feel. Temperatures have cooled but this really seems to help keep my little one warmer at night. Love this style blanket and arrived fast. I am happy with my nested bean blankets and wish I had purchased these for my first child. Will definitely recommend these wearable blankets to others.
Allison H.
Great quality, warm, cute, and works well. My baby went from waking 5-6 times each night to 2.
Calen P.
I have used the regular sleep sack and it helped my baby sleep some, but I just purchased the winter sleep sack and the first night using it my 5 month old slept 8 1/2 hours straight!
ashley W.
My son sleeps in this most nights. Sadly, it hasn’t extended his sleep any. Still only about 3 hours at a time, but this keeps him warm and has established a bit of a night time routine for him. When it goes on, it’s time to sleep. We will definitely be getting the next size up when it’s time!
Diane D.
The nested bean sleep sack is a MUST! Our son slept through the night at 2 months old. It’s seriously such an amazing purchase. Highly highly recommend!
Laura S.
3 months old and it gets chilly in the baby’s room. This sleep sack keeps her snuggly warm and she seems to appreciate the weight on her chest. She starts getting sleepy eyes as soon as we lay her down and snap on the shoulders.
Rachel L.
Love this thing! I won't make any miracle claims about all my babies sleep problems being solved, but I will say I have been sleeping a lot better knowing my baby is nice and warm without being tangled in blankets from rolling around in his crib.
My baby like to roll from his back to tummy and "gets stuck" and will start to cry. I have been placing him on his back (per usual) in his new sleep sack and while he still rolls from side to side, he is definitely less inclined to make full rolls during bed time. He just tends to hang out on his back until he falls now. I love it so far.
Laura M.
Super comfortable and warm for my little one as the season changes. Nested bean has become our most preferred sleep sack.
Carol B.
My new great grandson and his mom love the Zen sleep sack. The baby is sleeping much better which makes everyone happy.
Hillary P.
Must buy!!! I mean it, my baby was a good sleeper before I bought this, she would wake up once a night but after a few nights of using it she sleeps through the night!! I couldn’t be more happy. I love it so much I’d like to buy another one. Makes me sleep better too knowing she is staying warm as well

Our little guy was doing consistent 11-12 hour sleeps through the night until one day he just...wasn't. We thought we had made it through the 4 month sleep regression because this didn't kick up until right at 4.5-5 months. After weeks of adjusting wake windows, trying to improve naps for better night sleep, doing larger feedings, etc we wondered if he could be cold and also having a hard time getting himself back to sleep after jerking awake several times.
The first night with the Nested Bean winter (TOG 2.5) Sack, we saw an improvement of about an hour of total night sleep. We haven't unfortunately seen consistent improvement in night sleep duration but what we have seen is a reduction in the amount of times he's fully waking up (and then crying) between sleep cycles throughout the night. Which is a help! I wish it had helped his overall duration of night sleep but I'll take less crying any day!
Rebecca G.
We love this product!
Nichole C.
All babies are different, with that we haven’t seen a HUGE difference in sleep. Some nights are better than others. Overall, I think this will work better each night.
Johnny R.
Love it!! Free one please
Johnny R.
Love it please a free one!!!
Cloe U.
My daughter didn't seem to mind it does keep her nice and warm.
Jenna Z.
My only regret is not getting this sooner. My five month old would not nap anywhere but in my arms and at night would wake up every 45 minutes to an hour wanting held, after a week in the sleep sack she sleeps ~4hrs at a time at night waking only to eat, and is napping in her bassinet like a pro.
Joanna C.
This is SO COZY! Usually my baby wakes up with cold toes even though the room isn't all that cold. With the winter sack, she's been sleeping more sounding and with her toes all nice and warm. We've been using the Nest Bean since 2 months and we haven't dared to swap her out of it.
Johana B.
Love it
Rachel B.
Bought this as a baby shower gift for my newest granddaughter, so it has not yet been tried. Can't wait to see her in it when she's born!!
Grace V.
I gave it as a gift.
Kristin H.
So warm and so soft! My little guy loves it and I feel better knowing he is warm at night when our house is cold!
Alicia V.
My baby loves her Nested Bean sleep sacks!
Kisha D.
My 6 month old went from waking every 2 hours at night to waking once a night since wearing his sleep sac! Definitely recommend
Robyn G.
We love our next bean, I wish we could buy a bunch more! My daughter only wakes once or twice per night and goes back to sleep, allowing me to get some rest myself. The sack is soft and warm and I can be sure that she is comfortable when she sleeps!
Victoria C.
Too small . Baby is average 13m old and can hardly fit in it. Too expensive to order another. If it fitted well it would be perfect they're lovely and soft and the soft weight is great

How much weight is in the Zen Sack™?
The Zen Sack features a self-contained Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our products adhere to American Academy of Pediatrics (AAP) physiotherapy standards and Guidelines for Safe Sleep, which recommends a weight-to-body ratio of 1:10.

What’s the difference between Classic, Premier, and Winter Zen Sack™ products?
The only difference between these Zen Sack products is the fabric used for construction. Classic Cotton is made from 100% breathable cotton. The Premier Bamboo is made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength. Light-weight fabric, perfect for warmer climates. Bamboo is naturally anti-microbial and moisture wicking for dry, clean comfort. The Winter Cotton is made from 100% cotton and heavy poly-fiber filling. Our warmest option is perfect for cooler rooms or colder weather.

Is the Zen Sack safe for babies who roll over?
The Zen Sack was designed for rollers and tummy sleepers. It helps babies get longer, more peaceful sleep through all growth stages. The Cuddle Pad™ on the front of the Zen Sack is so light and flexible, it nearly flattens when baby rolls to their tummy. The sleep sack can also be reversed and worn backwards for tummy sleepers who roll independently, placing the gently weighted center on baby's back for continuous comfort through the night.
Put sleep disruptions to bed with the Zen Sack™
Seamlessly transition from swaddling
When rolling starts, swaddling stops—and some babies miss their cozy swaddle. Prevent wakeups with the gently weighted Zen Sack: So soothing, but tummy sleeper safe.
Stop sleep regressions
Rolling, sitting up, teething: New milestones can mean sleep regressions. Add the gently weighted Zen Sack to your sleep routine to help create positive associations with bedtime.
Help baby sleep through the night
Nighttime wakeups? The gently weighted Zen Sack is so comforting, it helps babies self-soothe—so they fall back to sleep on their own.
