It’s great!
AMBER J.
This is my second sack. I love the first one (winter sack in the color midnight), so I bought a second one. But this one seems to fit different. It’s tight under/around the arms. It also had the tags on the outside (just cut them off my big deal), but I’m beginning to wonder if it has a few manufacturing issues. Wish it fit like the other one I bought.
Maria B.
We love this brand! Our baby was 2 months + and we needed to get him out of the swaddle and tried different ways and other sleep sacks but he was sleeping in 2 hour intervals until finally, thank God, we remember one of our friends had given us a Nested Bean sleep sack! We tried it and after a week the baby started to sleep for longer hours!! I had to order more after I saw it worked for our baby. We ordered two of the winter ones since he likes to feel cozy at night and now he's sleeping like he used to with the swaddle thank God! We are very happy, love this brand.
Highly recommend it.
AMBER J.
Love love love!
Karen G.
I had the regular one that was passed down to us from family and he slept in it great but would get cold. So I decided to get the winter one and it’s been good.
Fabiola M.
easy to put and take off
Kira T.
My child named his sleep sack "waka" when he was 1 and his now almost 4. Waka is his most beloved possession. He is magical, can heal boo boos and is slept with every night. We had to buy a new one because he loved the old one to death.
Janki R.
Love the material and my 3 month old transfers from being held way better now.
Megan C.
The winter sleep sac is great. It keeps my baby warm during the cold winter nights.
Kat M.
Love this sleep sack! My son sleeps so much better with it.
Cody R.
Does the job well
Rachel K.
Helped great with my sleep training! Baby is sleeping through the night and is kept warm in the winter thick sleep sack! Love it!
Kayla K.
Absolutely love and highly recommend! I’ve always used the lightweight sack (name is slipping my mind) but my 14M old is still a big fan of his sleep sack and with the colder temps, needed something to keep him warm. It’s like he’s wearing a blanket! So soft, cozy, comfy, and warm without making him too hot. Went ahead and bought the next size up as he’ll be needing it within the month due to his growth spurt! Money well spent, every time.
John E.
This is user warm and cozy. My baby boy loves sucking on the beans; it helps him self-soothe!
Michelle F.
this sleep sack was a savior during the transition from swaddle to sleep sack. we got it as a gift and loved it so much we bought one as a gift for someone else! My daughters favorite

Great quality, I will need to size up. My baby has grown very quickly. Great company.
Melissa W.
My baby loves this sleep sack. We were previously using one where her arms were enclosed in the sleep sack and I was worried the transition to an arms free sleep sack would be difficult, but she took to it right away. Sleeping great and gets excited when she’s getting zipped in.
Courtney D.
It’s a lovely sleep sack and I love that it’s slightly weighted. It makes for an easy removal if needed.
Hailey D.
My baby LOVES his new sleep sack! He hated being in a swaddle and the first night he slept in the sleep sack he slept so much better. Also, I love that he has room to grow into it!
Stephanie C.
It’s great!
Jori C.
We love our little one's "bean sack". Just purchased the next size up for our 6-month-old after 3 months in his last one. It's a great design and a high-quality product. Highly recommend!
Avery S.
Our baby loves this sleep sack, and has been able to start falling asleep on her own with this! I love how cozy it is, so I feel like she’s staying warm through the night. It’s soft and easy to wash. Perfectly pleased with our purchase.
Avery S.
Baby sleeps through the night at 3 months with the help of this sleep sack! Had trouble with transferring her into her bassinet prior to utilizing this, and now she goes down without hassle.
Was a lot thicker than I expected. It's a comforter in a sack! It kept my baby warm enough to finally sleep in his room all night!
Alissa E.
We love ALL our Nested Bean purchases! The sleep sack has literally been heaven sent for us as our baby is a total contact sleeper and finds it super difficult to self soothe! We were so upset when we discovered we left ours in our hotel when we went on vacation recently, will definitely be adding another..or two or three to our closet soon.
Cassandra K.
My daughter loves this! She’s been in one every night since she about 2 weeks old!
Alexandra H B.
My baby seems to like it a lot
Paige D.
These sleep sacks are wonderful! So well made, easy to use and I swear it has helped my baby sleep so much better.
Amarpal K.
We have been using Nested Bean products since our twins were close to 2 months old. I like the product as it provides enough warmth and is cotton (as we try to stay away from synthetic products). I love the 2 zippers (we leave a little opening for better airflow just in case they get warm), especially since we are on the higher end of the reccommended temp.
The products feels as if it is 2 thick layers on the bottom and top.
Our sons hands would run cold and ever since we have been using the Winter Sack we do not notice his hands are cold. We were using the cotton and putting jammies underneath (thin to fleece). Our daughter runs warmer but has adjusted.
The Nested Bean product helped us get our 1st night of (overnight/longer streches) of sleep Night 1 of use and it was best thing ever.

This is the 4th Nested Bean sleep sack I’ve purchased. I purchased the first one for my son when he was about 8 weeks old. These had him sleeping longer stretches by night 4 or 5. By about 12 weeks, he was sleeping through the night! My son is now 17 months and he’s in the 15-24 month size. I will never recommend this sleep sack enough!!
Marissa E.
Love it so much! My husband and i want one for ourselves. We bought our daughter two just so we have a back up. So worth it!
Bethany T.
We have now transition to the sleep sack and LO loves it. We have used 3 different ones for the last year and have loved all of them.
Grace G.
Amazing, one night she didn’t use it because it was dirty and she literally was up all night. Ordering more because I do not want to go without it again for night time.
Peace
Love
Nazli B.
Amazing product, great soft quality and cozy for children. My daughter loves hers. Highly recommended.
Leslie B.
Used these with my oldest so I had to try them on the new baby and they didn’t disappoint. I got the thick cotton winter one because I like to keep it kinda chilly in the house and it works perfect. He only wakes up once a night to eat now, if that!
Camille B.
Best nights sleep with our Zen Sack Winter Hands down the best sleep sack!
Jennifer B.
I have an almost one year old who still wasn’t sleeping through the night. Apart from sleep training and the wildly expensive snoos, we had been trying all of the things, and to no avail. Then we tried this weighted sleep sack, and it was the golden ticket! 3 nights into using it, he started sleeping through the night and has continued to ever since. We are so thrilled and grateful!
Yue W.
Took long to get the sleep sack. Does not look like a completely new item. Two out of the three seals on the original packaging were torn. The sleep sack seems ok, but does not improve baby’s sleep as advertised.
Jada
I’m able to put my baby down to sleep now! I love it!
Kayla D.
Lifesaver!
My second child is such a light sleeper, and putting her down after rocking or nursing to sleep was impossible before I purchased this sleep sack. Swaddles, blankets, and regular sleep sacks were not working for us. My girl has slept so much better since the first night she wore this. I’m afraid to go a night without it! The weighted portion is just enough to mimic a hand placed on baby. We got the thicker material for winter, and it’s perfect for cool nights. She doesn’t get cold, and we don’t have to layer tons of clothes on her, just a simple sleeper underneath. So good, I will buy them in every size and TOG!
Kacey T.

Taylor E.
My baby went from not sleeping to sleeping through the night in her nested bean!!

First one was lost but the customer service answered really good and they send a replacement really quick!

So incredibly soft and cozy. Worth every penny!
Mrs S.
Love it! My baby would wake up every single time i put him down before we got it. It keeps him warm and cozy now and I don’t worry about blankets in order to keep him warm. So far he is still waking up as much as before but I hope it will help him as we transition out of co sleeping. I wish there was an option to have the weight evenly distributed for sizes 6/12 months.
Lauren E.

The reason that I didn't like this sack as much as the other products (Swaddle and Neo) is because it lacks the inner strap which holds the sack in place.

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.

Product is really good. My baby is warm and sleeping way much better.

This is so perfect. It’s big, and I thought it wouldn’t work at first. But my son loves it.
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.

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.
Julie
Great bargain!
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!

This is so perfect. It’s big, and I thought it wouldn’t work at first. But my son loves it.

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….

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!

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.

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.

Great bargain!
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!

How much weight is in the Zen Sack® Winter sleep sack?
The Zen Sack® Winter sleep sack features a built-in Cuddle Pad™, which weighs just 30 grams (Small size) 60 grams (Medium size) and 90 grams (Large size and distributed across the chest). Our winter sleep sacks are safely weighted in key areas, as opposed to all-weighted sleep sacks or weighted blankets, which the American Academy of Pediatrics has deemed unsafe for infants.
-
What’s the difference between the Zen Sack® Winter and Nested Bean’s other sleep sacks?
Nested Bean offers a variety of weighted sleep sacks, all of which are designed to calm like your embrace: Zen Sack® Classic, Zen Sack® Premier, Zen Sack® Winter and Zen Sack® Quilted. The difference between our weighted sleep sacks is the fabric used for construction. Zen Sack® Classic is made from 100% breathable cotton, and is perfect for year-round use. Zen Sack® Premier ,made from 70% rayon from bamboo for luxurious softness and 30% cotton for strength, is lightweight for warmer temps. Zen Sack® Quilted is a cozy transitional sleep sack, for when temps start to drop. And Zen Sack® Winter is made from 100% cotton, with a 2.5 TOG and heavy poly-fiber filling—the perfect winter sleep sack.
-
Are Nested Bean winter sleep sacks safe for babies who roll over?
Like all our sleep sacks, the Zen Sack® Winter was designed for rollers and tummy sleepers; The Zen Sack® Winter helps babies get longer, more peaceful sleep through all growth stages. The Small and Medium size winter sleep sacks have a gently weighted Cuddle Pad™ on the front that is so light and flexible, it nearly flattens when baby rolls to their tummy. The winter sleep sack can also be reversed and worn backwards for tummy sleepers who roll independently, placing the weighted center on baby's back for uninterrupted comfort all night.
-
What is the Cuddle Effect™—and how does the Zen Sack® Winter trigger it?
The Cuddle Effect is a proven metabolic response that babies experience when they are held, that triggers relaxation and well-being, improves sleep and promotes healthy development. Research on Deep Touch Pressure (DTP) shows that babies experience the Cuddle Effect when they feel gentle pressure in the places you naturally hold them. The Zen Sack® Winter is designed with gently weighted Cuddle Pads™ that calm like your embrace and trigger the Cuddle Effect for longer sleep.
-
Do Nested Bean winter sleep sacks meet industry safety standards?
The Zen Sack® Winter adheres to all Consumer Product Safety Commission guidelines around product construction, flammability and more. The Cuddle Pad™ in our sleep sacks is self-contained and cannot cause overheating, and the gentle weight does not restrict movement: For example, the Zen Sack™ Winter sleep sack is safe for tummy sleepers, rollers and side sleepers.
-
How long does it take the Zen Sack® Winter to work?
As with all our gently weighted Zen Sleepwear™, most parents report that our winter sleep sacks improve their baby’s sleep in 1 to 3 nights.
-
What is the Grow-with-Me feature of Nested Ben winter sleep sacks?
Nested Bean winter sleep sacks contain 2 sets of snaps on the shoulders. The bottom snap offers a snug fit, while the top snap offers more room as your baby grows.
-
How do Nested Bean winter sleep sacks hold up in the washing machine?
the Zen Sack™ Winter is made of the highest quality cottons, and is designed to withstand multiple washings. To protect the fabric quality, we recommend washing our winter sleep sacks in cold water, on a gentle cycle and tumble dry on low heat.
-
What is TOG—and how does it apply to winter sleep sacks?
TOG is a measure of thermal insulation. It is a commonly used term the textile industry to indicate how warm clothing is. The higher the TOG, the better thermal insulation it provides and the warmer it is. For example, the Zen Sack® Winter sleep sack has a cozy TOG of 2.5, just right for chilly nights.
