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 |

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.
- Zoe T.Verified Buyer6/17/25ReviewingSleep Sack 2.5 TOG Sleeved DaisiesRated 5 out of 5 starsMy baby sleeps better in this
I had the 0-3 month sleeping bag which doesn’t have sleeves and, once winter set in, my baby kept waking up in the night. I ended up changing to this one. It has significantly more padding, and is also padded in the chest area. The sleeves are nice and thick too, and fold at the wrists keeps her hands warm. She went from waking every hour or two back to sleeping 3-5 hour stretches.
