The Little Dutch winter sleeping bags with zip-off sleeves are ideal during the cold winter days. A winter sleeping bag ensures that your child can sleep comfortably and safely. A sleeping bag makes it harder for your child to roll over from back to stomach, to climb out of bed and to wriggle around. The winter sleeping bag has a front zip that opens from the bottom to the top. This prevents your child from taking off the sleeping bag by himself. The outer fabric of sleeping bag Pure Olive is made of cotton and polyester and the lining is made of 100% polyester. The sleeping bag is available in 70 cm, 90 cm and 110 cm.
