Amazing Sleeping bag
All sleeping bags we have from ergoPouch are amazing. The fabric is so soft and washes well. We have them in all the different tog ratings and it’s so nice knowing our daughter is at the right temperature over night. Highly recommend ergoPouch!

Perfect size for our newborn
So easy to use and fits our newborn perfectly - turns out she’s an arms up sleeper so great to be able to use this with her arms out after swaddling for the first few days.

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).
