Size Guide
Jersey Sleeping Bag
Our Jersey Sleeping Bag is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Jersey Sleeping Bag has a slim-fit, stretchy design similar to that of a swaddle and is recommended as baby's 'first sleeping bag' after the swaddling phase is over. Please use your child's weight to find the most appropriate and safe size for them. A sleeping bag 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 |

- Melinda V.Verified Buyer7/9/25ReviewingSleeping Bag 3.5 TOG Sleeved WillowRated 4 out of 5 starsSnug alpine weather sleeping bag
The little one is much warmer now in a 3.5 TOG as the temps in our house can drop down to 14 degrees overnight in the alpine climate.

We love our ergo pouch super cute and snug and bub sleeps well in it! Not as narrow as other brands and fits our little (big) guy better.
