Love it! It’s very soft! Machine washable and dries well on delicate cycle. Don’t know if baby’s sleep depends on it. Some nights are better some are worse. I really don’t believe a sleep sack can make it or break it… but overall I love it that it’s soft for baby’a skin and warm enough for my baby to sleep without pants and socks (only a onesie and diaper underneath).

We have transitioned from the SNOO using sleep sacks . This is by far the best one for ages 6 months on. It allows easy turning over during sleep . We are now in the second size and will be ordering 7 more before December. Game changer !!
Sherry F.
Great product. My grandson sleeps great. He knows when sak goes on its time to sleep.
Luciana B.
My grandson loves the Zen Sack, he carries it around like his blankey when not sleeping in it. It however is already too short for him, he's a big boy for his 18 months. It would be great if there were Zen Sacks for toddlers. Nested Bean has a great product. Thanks
KRISTIN N.
Love the winter one, so warm!
Kelly C.
Within the first couple of nights, we saw a huge difference in sleep! 10/10. Amazing.
Vicki H.
Love everything about this sleep sack. Easy diaper changes
Susan D.
Ordered for my grandson for Christmas. My daughter loves these to hav him sleep in.
Mariha H.
My baby was waking up every two hours before I got the Zen Sleep Sack. No joke, the FIRST NIGHT I got this wonderfully soft, warm, wearable blanket, she slept 10 hours straight. No more kicking the blankets off and getting cold and the little weight on her chest must be really comforting. I'm still in awe at how much it has improved our sleep and will recommend this product as a NECESSITY to anyone I know who has an infant from here on out with. Do you and your baby the service of getting a slightly weighted sleep sack. It works like magic.
Kayla G.
Perfect for winter nights!
Heather P.
My twins like them, they are so soft, and I find they do sleep a little better since we started using them.
Carrie S.
The quality is top notch! Sooo soft and zips easily. Warm and cozy perfect for winter. My baby does sometimes fall asleep faster with it on but not everytime. And he did sleep 7 hours straight last night. So improvements!
Christine M.
Absolutely love nested bean! Was gifted our first by a friend and it really really helped the difficult transition from swaddle. The winter weight is perfect for chilly nights and babe is always nice and cozy!
jessica s.
We were transitioning from the Merlin Sleep Sack to this and couldn't be happier. By the second night she slept 12 hours straight. I was skeptical so it was a nice surprise that it actually worked! I ordered the two winter ones, just wish they came in the other fun colors like the classic one does. We now have two winter versions and one classic and will likely order one more classic one for when the weather gets warmer. Thank you!
Ashton S.
Bought these to help my twins transition from swaddling to hands out. They love these! They stay warm and the weighted portion seems to help them fall asleep faster. We will purchase again as they get bigger.
Kylee Q.
We've been using it for a couple weeks and I haven't seen a ton of change. Can't get much worse than we are experiencing so going to continue to use it. Worst off, it's just a warm safe blanket.
Jinxuan Y.
I love nested bean. I love the quality and how cute everything is! It is expensive but my baby sleeps so well in it and it’s just so cozy!
Jaclyn W.
So thick and warm!
Patrick J.
These are great! We really liked the zen swaddle and were hoping they came in larger sizes. This was a good alternative though
Stephanie R.
I was a little worried about the cotton being heavy enough, but was very surprised when I received it. This is perfect for colder nights/winter.
Lisa C.
The Zen winter sacks are soft and perfectly warm for our little one. He wakes up warm and toasty.
Stephanie C.
Little one loves this sleep sack! We were noticing that she seemed to be waking up at night because she was cold in the regular nested bean sleep sack so I picked up the winter ones. Problem solved!
Rachel T.
Our son is almost 4 months old. I sized up because our little man is growing so fast! I absolutely loooooooooooove the thickness of these winter sacks. It is perfect for this time of year. First night he slept soundly, but because he's not quite 4 months old yet he was still wiggling a bit. So I stopped using the sack. Regardless, I'll be using them as he gets older. ❤❤❤❤
Amy A.
We bought these for our babe after using the zen sleep sack. And I was so happy to have heavier sleep sack for him since we like to keep the house cooler at night. I love love love these products. Our babe was having such a hard time sleeping and soon after we switched to Nested Bean, he was sleeping through the night. I would recommend to anyone!
Kristopher I.
Our Little one loves these sleep sacks. Keeps him warm and snuggled at night.
Alexis G.
We have been using the Classic sleeps sacks and love them. We bought the winter sacks, and OMG, I want one for myself. They are great, and my kids love them. I highly recommend them for fantastic quality.
Diana K.
I really love the look and the quality of the sleep sack. It’s super cozy and warm but still breathable and very soft. It is a bit on the short side. I ordered the 6-15mo and even though my baby is 4months, it’s already snug with not much excess room at the bottom. I can’t imagine it fitting comfortably for more than 3 more months. As much as I wanted the weighted egg to work to help sooth our baby at night, we didn’t any difference in his sleep. I think there are just too many other factors that could be impacting his sleep that a bit of weight on the chest really won’t do much. However, I still think they are worth it just for the nice quality material.
Melissa S.
Baby is sleeping so much better!!!
Sasi W.
It’s not work for my baby! So sad
Margaret A.
LOVE LOVE LOVE! We’ve been believers of these products for the past two years with our first born. Now with babe number two, we needed the winter sacks. We received them and started using them during the 4 month sleep regression, and as always, A MIRACLE! Babe sleeps soundly all night, waking once for a quick feeding and right back to sleep. SWEAR by these awesome sleep sacks! Just buy them!!
Jennifer C.
I started using Nested Bean Sleep Sacks since my son was about 4 months old! So soft and easy to manage! I love the adjustable straps at the top on his shoulders and the two way zipper is perfect! He is now 18 months old and still wears them. My friend just had twin girls so when she asked my opinion, I bought her two to try on her own! I bet she will love them for her babies.
Katelyn T.
It was given as a gift and the recipient was thrilled.
Michelle D.
I bought this when my baby was 4 months old and starting to flip over and sleep on his stomach. He wears it backwards so the little break filled comfort thing is on his back. He sleep well with it. No miracle 'now sleeps through the night!' story here, but he falls asleep faster, and sleeps a little longer.
And the material itself is lovely and warm and just feels good quality - which I was happy to find after having a little buyers remorse after spending so much on these.
I would recommend to anyone. Love them.
D M.
Great quality. The sleep sack feels like I blanket I would throw over myself.
Ling C.
It's good material but unfortunately doesn't work for my baby.
Plamena M.
It is starting to get cold where we live and the winter sleep sack definitely keeps my 11 month old cozy at night, he actually sleeps better since we got them.
Erica B.
The material is very soft and the warmth of it is perfect for cold fall/winter nights. The zipper is also a very nice quality which I found to be an issue with other sleep sacks.
Elisabeth H.
Our babe started rolling very early and was too small for other sleep things to help transition out of a swaddle. These sleep sacks were super helpful! We have the regular ones and also these warmer ones for winter - they’re definitely warm. They feel like a duvet almost. We put our babe in a light jammy and this sleep sack and she’s great. We really like them!!
Paulette B.
The sleep sack did the trick. My almost one-year-old grandson was waking up frequently during the night and it was a lot of rocking and soothing to get him back down. Te sleep sack eliminated most of the soothing and rocking. He goes back down quickly and right back to sleep: a sleep-saver for us!
Allyse H.
We got this option because my 8 month old daughter’s room is cooler than the rest and we wanted a TOG that would keep her warm. She also has been waking up a lot at night so we thought we would give it a try. It keeps her warm and she has been sleeping better. While I appreciate the thought of the snaps and zipper, I am still getting used to it as she is a wiggle worm and likes to roll onto her side when she sleeps...so we are still figuring out the best sleep routine with it. I am satisfied overall!
Eileen S.
The material is good quality
Lacey L.
My son loves the weighted sleepers! He started sleeping better the first night! The winter ones are thick and cozy, like climbing into a warm comforter
Charles R.
All Star Swaddle this is perfect for the independent baby that needs the weighted comfort and free arm space
Cheree F.
I love how snug these are like a sleeping bag. Super cozy and warm. My son has been sleeping through the night since he was 2 months because of your sleep sacks. I reverse mine because my little is a stomach sleeper.
Thank you for creating these!!
Dragana P.
We are totally un Love with the Nested Bean Sleepsack Already ordered the second time! If your baby needs sleep and you as well, I can only recommend it! It literally saved us
Patricia M.
These came highly recommended from a mother who used them with their child.
So thrilled with the two pack because we are expecting two grandchildren in our extended family and love getting gifts for both of them at the same time. I will purchase the next size as they grow.
Many thanks for an excellent product that arrived very quickly!
Destiny D.
We’ve been using the swaddles/sleep sacks since she was born (she’s 13 months now), and she loves them. She will pull one out of the drawer and cuddle up with it when she’s ready for a nap!
Joseph B.
I absolutely love this product. It is easy to put on and take off, and my baby girl sleeps through the night. My baby girl had started rolling over when she was 6-7 weeks, so we had to stop swaddling early, but she still had her Moro reflex, so we got the Zen One first and we loved it. We used it as a transition tool for a couple weeks, and then we decided to get the sacks. They are great! We got the winter version and we expect to continue using them during summers with AC. My baby girl has been sleeping 9pm-7am since 2 months old!
Nathalie H.
Very good quality! I love it
Beth M.
Bought these as baby shower gifts for my sister and also my daughter.. Both babies are due Feb/March.. My sister received hers and was very excited to receive it... We will have to wait until the babies arrive to see how or if they work.....
Alyssa M.
Absolutely love these sleep sacks. They are so warm and soft. My daughter has been sleeping alot better.
Jon C.
Great product. Wanted a smaller size because the ones I ordered are big. It is a bit complicated to exchange it, which with a baby in hand you just decide to keep it even if you have to wait an entire year.
Hana W.
This sleep sack is the BEST quality and Nice and snuggly warm for winter! It’s also so easy to get on and off with the shoulder snaps! The best!
