Our baby sleep bag will keep the baby cosy in room temperatures of between 16°c-20°c. Designed as an alternative to traditional sheets and blankets, this structured design ensures babies can’t kick off covers in the night, but the double popper system for extra security means they can’t slip down inside either. All the zips and enclosed seams are tailored to avoid contact with babies’ delicate skin, and zip heads feature a protective fabric cover. Always ensure you use the correct size baby sleep bag for your baby. Please check the babies's weight as that will determine the correct 'size' to use. Never use a baby sleep bag that is too big for your baby.
