Lightweight summer sleeping bag made from soft cotton muslin is perfect for warm summer nights. The breathable material keeps the baby comfortably warm while preventing sweating or chilling. The concealed zipper not only looks great but also protects against cold and is gentle on the skin. The baby sleeping bag should fit snugly and have a good fit around the shoulders. There should be no less than 10 cm of space between the feet and the bottom edge of the sleeping bag.
