Size Guide
Sleep Sack (formerly known as the Jersey Sleep Sack)
Our 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 sleepingbag is so nice and warm, and soft. It’s very easy to put the little bay arms through the sleeves.
I really recommend!!
- Victoria M.Verified Buyer12/11/25ReviewingSleep Sack 2.5 TOG WillowRated 5 out of 5 starsBaby loves it
I needed a sleep slack to replace his favorite which didn’t come in a bigger size (he got too tall). He loves this one and the switch was super easy! It’s so soft and nice and thick, he’s a happy baby.
