Size Guide
Jersey Sleep Sack
Our Jersey Sleep Sack is a baby and toddler Sleep Sack designed for arms-out sleepers (usually from around 3 months of age). The Jersey Sleep Sack has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'First Sleep Sack' after the swaddling phase is over. Please use your child's weight to find the most appropriate and safe size for them. A sleep sack should be well fitted around the neck and the armholes to avoid your baby slipping through. It should also be bell shaped in the bottom to allow for easy leg movement. Please do not size up to the next size until your child meets the weight requirement, for safety reasons.| ergoPouch size | 3-12M | 8-24M | 2-4Y |

This is my first time shopping from Ergo. I was looking for a sleeping bag that was made from 100% cotton without any synthetic materials and so far I am very please with the quality! I would definitely recommend this brand for anyone who is looking to invest in their baby’s sleep. I also like the fact that the design has been made to last up to 12 months.

I had my son in LTD and begun my daughter in LTD also, then I got gifted an Ergo Pouch and I had to have more. They’re easy to use, I love that the swaddles are transitional straight away, a very handy option for if you have an early roller like I did. They’re soft and gentle, wash and dry wonderfully and come in very cute designs. I love that there is enough hip wiggle room for my daughter and am always satisfied that she is warm or cool enough for her sleeps. Each pouch came with a room temperature monitor and guide chart to assist you in what to dress baby in before adding the swaddle. It’s super handy to know these things as babies cannot regulate their temperature for quite some time. Such a handy freebie to add.
