Ergo Pouch Jersey Sleeping Bag is an organic baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age). The Jersey 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. The safe-sleep approved design is made from soft, stretchy GOTS certified organic cotton that is non-toxic and gentle on baby's skin.
