The sleeping bag does not restrict the baby’s movements and does not cause overheating and excessive sweating thanks to the free air circulation inside the sleeping bag. The child can move its legs freely and sleep well, even if it fidgets a lot. With the sleeping bag, the baby can “wander” around its cot, never throwing off the bedclothes. Zaffiro sleeping bags are made of “breathable” cotton exclusively. During sleep, your child should have a cover that enables natural temperature control.
