Cosy and warm.

My favourite sleeping bags
I have always bought ergo pouch because of the quality natural fabrics & the quality of the make. You can wash these time and time again and never have any shrinkage
Sleeves too short
We have a couple of these sleep sacks that were gifted to us for Christmas and love how warm they have keep my baby during this winter in a house without great heat. However the sleeves are just too short, so his hands are always popping out of the hand covers and get super cold unfortunately. I don’t know if my son has long arms relative to other babies (he seems pretty proportional to me, he’s in the 60% for height) but the sleeves have been too short the entire time we’ve had these sleep sacks (from 5m until now 8months).
Great sleep pouch
Warm, sleeves are like a sweat shirt material. Washes and drys well.
3.5 TOG!
3.5 TOG sleep sacks is the reason we found ergoPouch, and 2 years into using them we are still happy customers. My toddler loves his blue dragonfly sleeping bag.
Love the sleep sack
Two babies in and all I use is ergopouch. The best sleep sack.
Sleep Sack 3.5
Absolutely love the ergoPouch sleep sacks in general and the 3.5 TOG for the colder nights!!!
Highly Recommend!
We live in a place where it is not unsurprising when it gets to -40o F, and our winters are loooong. We have had these sleep sacks for 2 winters now, sizing up when our little dude outgrows, and they keep him sleeping soundly.
So cosy and great quality
We bought two of these for our twin girls and they seem to really love them. They are a really good quality material, nice and thick, and keep them really warm and cosy. The fact they are much longer than the standard 0-6 month sleeping bags is also great as our girls are on the longer side and were finding the shorter bags annoying. We'll definitely buy again.
Keeps her warm and safe.
I just wish they had a smaller size. My baby rolled over very early, and is in the 2nd percentile- so small. This was the smallest 3.5 tog u found that had sleeves for a two month old.
Super snug
Our little one was waking in the night a lot more before we got this. Keeps her snug all night through.
3.5 TOG Sleep Sack
We purchased this sleep sack in hopes that it would help baby sleep better overnight and it did just that. The sleep sack itself is well made. I was worried the zipper being front and center would be an issue because our baby likes to sleep on his stomach but no issues! He's never slept better.
Always reliable
Baby has never had any issues with the products, this is his third sleep sack and we never have any concerns. Wish it was slightly cheaper so I could stock up more.
Great
Great item, only complaint is the tag is in a spot on the neck where it could get itchy. Would make more sense to put it inside the body of the pouch.
Very soft & warm, and a beautiful print
This sleepingbag is so nice and warm, and soft. It’s very easy to put the little bay arms through the sleeves.I really recommend!!
