Kept our tiny baby warm and she still loves it a year later!
When our tiny daughter was only a few months old we found she was getting really cold at night, dropping her body temp. We were so worried and no pajama or swaddle was helping. We bought this and it turned everything around and now, at 13 months, she loves getting "snuggly wuggly" in her sleep sack ready for bed. It's beautiful quality, smooth texture and enough room for her to grow. Easy to wash. I wish we'd known about it sooner. Would highly recommend.

HIGHLY RECOMMEND
I absolutely love this sleeping bag and so does my little girl. It was recommended to me by a safe sleep group who are super vigilant and fussy with their recommendations. The fabric is very very soft but not flimsy. The zip is strong and well made. It is covered at the ends so its comfortable for little one. It's got two strong press studs at each shoulder and one under each armpit to make it fit well for little babies. It comes with a thermometer so you can check the room temperature so you can dress baby according to the heat. The thermometer isnt the greatest for getting a precise temperature. It comes with a clothing guide too so you know what to dress your baby in for the right temperature so this helps reduce the risk of SIDS it is a bit more expensive than other sleep suits however your paying for absolute quality and more importantly safety. VERY HIGHLY RECOMMEND.

Love it! Warm and comforting.
Feels and looks great! Our little boy wouldn’t sleep for more than 2 hours throughout the night and as soon as we put him in his Woolino sleeping bag, he slept for 5 hours! He was a little bit sick around the collar area but the sleeping bag was quick to dry and it didn’t soak through to his clothes. He also leaked through his nappy and sleep suit but the sleeping bag didn’t absorb anything or smell. I would definitely purchase another one, no need to worry about togs or that I have to keep buying another sleeping bag as every 6 months as he grows.

Soft, comfy and warm without the ticknes and bulkiness
It's a pricy, but works well, is very soft and comfy. After my five months old granddaughter cached a cold & runny nose, I decided to purchase a wool sleeping bag. It is worth the money.

Quality sleep sack for regulating temperature and room to grow into
My 8 month old gets very warm and the house is very well insulated, his room is always about 25 degrees celsius. It has been hard to find a comfy sleep sack that will regulate his temperature appropriately and after a few wears he really seems to like this sleep sack. A bit of a splurge at the price but saying that we will get the value from it as jt can be used year round and should last him until he is 2. Will be saving up to buy another!

four seasons sleeping item.
Baby sleeping bag for ages 2 months till 24months old . It's so worth the price. Soft well made and versatile a perfect gift. By time he's 2 months he'll be ready for this four seasons sleeping bag. I love that it can be applied for use in a pushchair pram or cot. Brought as a newborn baby gift for my new grandson his mom loves it

Great for warmer weather
It is very overpriced because it doesn’t do what it says “regulates body temperature” it feels like a luxury 1,5tog sleep sack. I would not recommend for a cold weather or cold nursery. It’s soft and snug, very handy with the holes for the car seat or pram straps. It keeps my baby cool and comfy when it’s 24-25 degrees but he is freezing in a 22 degree room.

I'm so glad I invested in a Woolino sleep sack that lasts from 2 months to 2 years, as opposed to buying one for 0-3 months, 3-6 months, 6-12 months, 12-18 months, and so on. Do the calculation because in the long run, you'll save money with one of these instead. As soon as your baby is done with the swaddle, you can use this exclusively going forward. I know it's a lot to pay upfront but if you buy 2, you get 10% off. I've also seen them on eBay for slightly less. They're luxuriously soft and have held up to many washes/dryer cycles so far. I really commend Woolino for including so many functional features: snaps at the top (who wants to wriggle their baby's arms through holes), additional snaps to close up the arm hole (for the tiny babies), and easy two-way zippers (for diapers changes). There's also a hole in the middle of the front and back so you can transport them to the car seat/swing but I wouldn't leave this on them if they were in those items. They claim to be all season and there's a chart that tells you how to dress your baby based on the temperature (really hot temps would just require them in a diaper and this), but you still have to use your own judgment. On blistering hot days (100+ degree F), I could use this but only if I had the a/c running.

Um ótimo saco de dormir. Serve para todo o ano o que evita comprar vários sacos com tog diferentes. O caro sai barato. Pena não haver na Amazon as outras opções:dos 0-6 meses, dos 6-18.

After trying many sleep sacks, I was tired of constantly thinking about TOG values, size/length, and having back ups for washing. I bought a Woolino and haven't looked back. They are roomy but customizable to fit baby. They have snap closures at the shoulders so if you have a baby that hates putting their arm through the armhole, these are great. The extra room for growth also means room for movement when my baby is settling and self soothing with some wild movements in the crib. He never gets tangled in it and hasn't seemed too hot, though we haven't used this in the summer yet. I've washed a few times and it has held up well. Dryer with no heat only, and once in desperation to get the laundry done quickly I did a moderate spin cycle instead of gentle, and it stood up fine. I compared it to a new one that I had bought as a backup and didn't see any shrinkage after washing in this manner. We had some spit up/throw up/drooling mishaps and there was no staining, but I did wash promptly following any breast milk debris being on it. Very high quality feel. The merino wool has withstood a lot of kicking and pulling from my baby getting his feet up and pulling down on it, stretching and causing friction to the layers. You would never know. Zippers never catch or get caught on the material. Snaps never feel weak or weaken the fabric they are attached to. FYI had it for 3 months and my son is 6 months old. Used swaddle Up, ergo pouch, and halo sleep sacks previously.
