The ergoPouch Jersey Sleeping Bag is a baby and toddler sleeping bag designed for infants who are rolling and sitting. The ideal first sleeping bag after swaddling phase is over. 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 of baby's skin. The ergonomically designed bag 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. The 2.5 TOG Jersey Sleeping Bag is perfect for keeping a child warm overnight in rooms 17-23°C. The TOG rating means that there is no need for additional blankets in the cot when using this product, making it a safe-sleep option. Parents can be rest assured that the breathable organic, natural fibres will help regulate their child's temperature and prevent overheating. Parents can follow the FREE room thermometer and What to Wear guide provided with the product, to layer appropriately underneath to keep their child warm.
