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 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. The ergonomically designed sack features a bell-shaped bottom to promote healthy hip joint development and is approved by the International Hip Dysplasia Institute, and the material is stretchy to allow baby to move more freely and stay comfortable while they sleep.

  • Many appreciate practical design features like easy diaper access, arm openings for developmental freedom, and extended sizing across growth stages
  • Most customers view the sleep sacks as excellent long-term value, with families repurchasing for multiple children or planning to resell
  • A few mention rare minor issues like occasional pilling or fit concerns, but these are isolated and do not affect overall satisfaction

Amazing Sleeping bag

All sleeping bags we have from ergoPouch are amazing. The fabric is so soft and washes well. We have them in all the different tog ratings and it’s so nice knowing our daughter is at the right temperature over night. Highly recommend ergoPouch!

Perfect size for our newborn

So easy to use and fits our newborn perfectly - turns out she’s an arms up sleeper so great to be able to use this with her arms out after swaddling for the first few days.
