The zip-up ErgoCocoon Swaddle Sac by ErgoPouch makes swaddling a breeze! Made with stretchy organic cotton, it keeps little ones snug and secure without the hassle of wrapping. Snaps mean arms can either be free or stay tucked in, and the cocoon converts to a sleeping bag when it’s time to transition. The two-way zipper allows for quick and easy diaper changes, making sure baby stays comfortable all through the night. For a cozier night's sleep, this baby swaddle has an inner layer of soft, bamboo terry for extra warmth on cooler days and nights. Great for Spring or Fall babies.
