We do not recommend sizing up.The sleep bagshould be well-fitted around your child's upper body for a safe and secure fit. We suggest using our recommended sizing guidelines to find the correct size based on your child's age, height, and weight. Your baby should not be below the minimum recommended weight.
I bought this as a gift for a baby due any day now. I was disappointed that the package was smashed and the box was ripped since it looks beat up. No care in sending the package.
This sleep sack is a great option for us as we’re transitioning our 2 month old out of swaddling! She is showing some early signs of rolling already but loves being swaddled, so we needed something sleep safe but still cozy. We wanted to use a weighted sack but learned they are not considered sleep safe. This one is not weighted but has a nice natural thickness that makes it snuggly. We’ve been using it during day time naps to get her used to not being swaddled and so far she seems to love it! I do wish it had a sleeved option since she runs really cold. We have to make sure she has very warm pjs underneath but I know it’s better for her to be too cold than hot anyway, so we just dress her accordingly. I did wash it once on a delicate cycle and it already looks a little faded but it’s a great deal and doesn’t necessarily need to last a super long time. We will probably buy the next size when she outgrows this one. I would recommend it!
Nice, soft and lightweight summer sleep sack. She made the switch from the heavier weight wool one with no complaints at all. I’m happy that as the weather gets hot, I don’t have to worry about her getting sweaty overnight.
My toddler used to freak out multiple times midnight because she rolled over and her little blanket doesn’t cover her feet anymore. She will wake up screaming “toes! Blanket over toes!” Or “leg! Blanket over leg!” This sleep sack is suck a life saver, light yet soft. I’ll be getting the all season wool ones for winter for sure.
My first experience with the sleeping bag and I couldn’t choose better. I got both the Ecolino organic cotton basic baby sack (0-6m) for the day naps and the 4 Season Ultimate (2-24m) for the nights. Ready to order more 😊
The fabric is soft and luxurious. The arm holes are big enough to get into easily. The zipper function is smooth. Overall quality is excellent. It’s bigger than I expected, but that’s fine. My guy is a smallish 15 months, and I’m sure he’ll wear the 6-18mo size past 2 years old. I couldn’t imagine putting him in this when he was 6mo, though!! It would’ve drowned him. My only gripe so far is the asymmetric zipper. I find it difficult to situate him in, and it’s hard to orient myself to where the arms are. I’m sure we’ll get the hang of it, but a center zip would require less practice.
We absolutely love our Woolino sleepsack and we love that it grows with our son until he is 3! The quality is awesome and the pattern is so cute. We don't have any complaints!
My daughter sleeps well in this cotton blanket. Just perfect for summer season. It is quite long for her but that isn’t a problem since she’s going to be sleeping in it =)
I recently switched my son (just turned 18 months) from his Woolino 4 seasons sleep sack to his new Ecolino cotton sleep sack and, as with all his Woolino sleep sacks, he continues to have the best 12 hr sleeps at night, and epic 2-3 hr daily naps! I love that he is safe and cozy and that I don’t have to worry about him overheating or being irritated by the fabric. I was skeptical about paying so much for a sleep sack, but the design & size truly allows for the sleep sacks to be used for 2 yrs so it is money well spent.
We were hooked on Woolino with the 4 Season Ultimate Sleep Bag (best investment!) so when it came time to upgrade our “nap sleep sack”, we turned to Woolino. This is a great light/medium weight sleep bag. I trust the quality and the brand. Plus I am so grateful that this will last our daughter a long time as opposed to other sleep sacks that are only for a few months... what a waste. Thanks Woolino!
Our baby Alandra loves her woolino sleeping bag. She is now 6 months old and we are planning to order a bigger woolino sack for her that she could use for up to 2 years old. We just did a sleep training program using the sack from 0 to 6 months and that helped us a lot simply because we didn’t have to worry that our baby will be cold at night. The quality and durability of woolino sacks is amazing. Thank you for this great product.
I love Woolino! They have the best products and this is the fourth sleep sack I've purchased. I deducted one star because a huge hole developed after the second time washing on delicate and hang drying, but they have a great warranty program so they replaced it quickly. My kids sleep so much better in both the cotton and wool sleep sacks, and I couldn't imagine nights without them.
Ours second Woolino sleep sack. The zipper is to the side so it’s most comfortable. Cotton is super soft. The print stays in a good shape even after many washes
Love this sleep sack in cotton and love the woolen ones as well. My daughter is always the perfect temp at night and she finds them comforting—they’re soft and warm and cute! Highly recommend - quality is a lot higher than competitors.
I ordered the cotton sleep sack for my grandson ( still have some time before he gets to use it ). Just wanted to say that it is absolutely beautiful, very well made with meticulous finishing. The fabric is light and soft. The pattern is cheerful and soothing. I definitely recommend it! I am sure I’ll be buying more sizes pretty soon!
So bummed. This feels so nice and the zipper is very easy to use but the zipper pull is very large and when closed is right under my baby's chest. He sleeps on his stomach and this causes him to wake up more often and wake almost every time I put him down asleep.
I got the 18-36 month size and it was much bigger than I expected. Was worried she wouldn’t agree to go in it, but she loves it! Lightweight for summer.
I got it to discourage her trying to climb out of her crib.
Love this sleep sack! I needed something lighter weight in the summer for my sweaty babe. The material is perfect, organic, and the design is adorable! I really appreciate brands like this!
