The Gots-certified muslin sleeping bag ensures that babies can move comfortably and safely in it. The sleeping bag should be worn over pyjamas and eliminates the need for unsafe blankets in the cot. It is made from breathable organic cotton muslin and allows air to circulate to reduce the risk of overheating. In cooler temperatures, the sleeping bag can be used with warmer pyjamas. The practical inverted zip makes it easier to change nappies at night or during a nap. The sleeping bags from aden + anais are designed for quality and durability and are manufactured to the highest ecological, social and processing standards.
