## Description

desertcart.com: Woolino Merino Wool and Organic Cotton Baby Sleeping Bag - 4 Season Classic Sleep Sack - Two-Way Zipper Sleeping Bag for Baby and Toddler - 0-6 Months - Butterfly : Baby

Review: Best money I've spent on baby sleep sack! - When our son started to roll over, we began to look for a good sleep sack to replace his Magic Merlin's sleepsuit; and boy it was quite the search! I ordered multiple different ones from cheap to expensive on desertcart (Tommy Tippee, Gunamuna, Kyte Baby, Burt's bees, Halo, and some other random brands that had great reviews) until I stumbled on to the Woolino sleep sack randomly. They all came in the mail and even though some were soft and light, fluffy- the quality just wasn't there and most were made out of synthetic material with cotton shell for softness or like Kyte baby for example- great material, breathable, but made with multiple layers and when my son moved around the one night we used it, it bunched up all around his waist and legs with these different layers twisting around him. Most were not breathable and baby is either sweating or too cold in it. Woolino is by far the best: breathable, temp regulating for colder or warmer nights, very well put together with a heavy duty zipper that opens from the top and the bottom for easy diaper changes, size that it comes in will last a long time with room for baby to grow and still use it for a while, and lastly my baby boy never gets tangled up in it. Anyone who wore merino wool socks in the winter knows how amazing the material is and that it keeps feet warm and dry; this is the same quality merino wool if not better with same advantages. These sacks are not cheap by any means and I understand the hesitation most people have, I did too...but you do get what you pay for I believe. Instead of buying multiple ones over the next couple years due to sizing or wear due to quality of other cheaper ones, I feel that with Woolino sacks it may save money in the long run. I did ended up buying another one, so I have two and had an issue with the zipper catching a little. I emailed the company through desertcart and Elizabeth from Woolino emailed me within hours and replaced the sack without any issues or time wasted. I am truly blown away by the service they provide and the 1 year warranty. Good customer service is very hard to come by nowadays and I will definitely support their company not just because of the great product they provide, but because of the amazing service.
Review: Best sleep sack - Top tier sleep sack. Temperature regulating, well made. The material is thick but very soft and breathable. My baby sleeps the best in these sacks. Pricey but worth it. They last a long time and are roomy to allow for growth. You can feel the quality of the material. The sturdy dual zipper makes changing a breeze.

## Questions & Answers

**Q: Is there much difference in the amount of extra fabric at the bottom of the 6-18 month and universal size sacks?**
A: I bought size 6-18 months for my kid since he was 2 months old and then I got 18-36 months when he turned 12 months.  He is almost 18 months now, still using it fits well.  There are enough extra farbric at the bottom for him to turn around if that's what you were asking.

**Q: What size should i get for a 14 months in early October? Baby is 30 inches, 26 lbs. Ideally we could get two winters use from one item.**
A: Woolino 4 Season BASIC sleep bags (standard sizes) - THIS LISTINGSize                           height                 weight  0 - 6 months;  22-27"  (56-69cm);  10-18lb (4.5-8kg)6 - 18 months;  26-33"  (66-84cm);  16-27lb (7-12kg)18 - 36 months;  32-39"  (81-99cm);  25-36lb (11-16.5kg)Woolino 4 Season Sleep Bags (universal sizes)Size                               height                     weight2 months -2 years;  23-35" (58-89cm);  10-32lb (4.5-14.5kg)2 - 4 years;   34-42"  (86-107cm);  26-42lb (12-19kg)Universal size listing link:http://www.amazon.com/Woolino-Season-Sleep-Merino-2mo-2yrs/dp/B004FJL92K

**Q: What is the actual length of the fabric for each size sack? Not the length of the baby, but the length of the sack?**
A: Woolino 4 Season BASIC Sleep Bag Lengths (standard sizes)Size			Length 0 - 6 months; 	27" (69cm)6 - 18 months; 34" (86cm)18-36 months; 40" (102cm)

**Q: Baby is waking up multiple times legs/feet as well as arms are cold to touch. Room is 69/70, should I be using wool pjs underneath as well?**
A: Yes, at 69f you may dress your child with long sleeve pajamas, wool or cotton. Here are the dressing suggestions on the back of paper thermometer that came with your sleep bag.Touching hands or arms is usually not a good indication of a child being cold. Touching their belly or behind their neck while they sleep will indicate better if the child is hot or cold. Also, please note to place the room thermometer in nursery on the crib level to make sure you're getting the correct readings. I hope this helps.

### ⭐⭐⭐⭐⭐ Best money I've spent on baby sleep sack!

### ⭐⭐⭐⭐⭐ Best sleep sack
*by J***E on July 20, 2025*

Top tier sleep sack. Temperature regulating, well made. The material is thick but very soft and breathable. My baby sleeps the best in these sacks. Pricey but worth it. They last a long time and are roomy to allow for growth. You can feel the quality of the material. The sturdy dual zipper makes changing a breeze.

### ⭐⭐⭐⭐⭐ Awesome sleep sack
*by N***R on June 21, 2016*

I was very hopeful of this sleep bag based on the reviews and I am pleased to say it does not disappoint. The quality is top notch and it looks awesome on our little man. He is three weeks and close to 8 lbs and he has some room to grow into the length. It fits him well in the shoulders and neck and doesn't ride up above his face, which is great because I don't have to worry about him when he sleeps. I love the double zipper, which makes it easy to take him out and out him back in without too much disruption during late night feedings. The material is very soft and washes well too. He has spit up on it a few times and it wiped up well and I don't have to throw it in the wash frequently. I will definitely be purchasing more of these as he grows; they make a 2 month - 2 years version that will definitely become part of his wardrobe. I may splurge and get another one of these so we have a backup since it will be good up to 6 mos, depending on how long he is at that time. Plenty of room in it, but not so much that he swims. Seems to really help him regulate his body temperature very well. It is summer time in Denver and we either have the A/C on or the attic fan if it is cool enough outside at night. He does well in this and we don't need a blanket, which is another plus and one less thing to worry about as he sleeps. I highly recommend this sleep sack to anyone looking for a high quality product. Piece of mind for safe sleeping and helps regulate body temperature naturally.
