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 |

My 4 month old loves sleeping in her ergopouch sleeping bag. It keeps her warm but lets her have her arms free

Our little one was waking in the night a lot more before we got this. Keeps her snug all night through.

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.
