Our Jersey Sleeping Bags are made for sleep. Created from a luxuriously soft and stretchy, organic cotton, these sleep sacks are ideal for transiting from the ergoPouch Swaddle. These sleepers are a great way to ensure your little one is kept snug and cozy while sleeping. This product is suitable for babies 3-12 months and toddlers 8 months up to 24 months. It’s designed for children who are sleeping arms-free (not swaddled) and prefer to feel a stretchy fabric close to their bodies, similar to the ergoPouch Swaddle. This staple piece is made with a comfortable jersey cotton fabric with 4–way stretch, similar in texture to a soft t-shirt. All ergoPouch sleeping bags are made and filled with natural fibers. Natural fibers have been selected for maximum breathability and temperature regulation, also making them ideal for sensitive skins and babies with allergies. All ergoPouch sleeping bags come with a double ended zipper for easy diaper access. Sleeping with natural fibers can help your baby get a better night's sleep. Natural fibers disperse moisture from the skin, providing an even warmth and body temperature. ergoPouch sleeping bags are all highly breathable, keeping babies consistently warm without overheating.
