The inner sleeping bag from Träumeland is simply pulled under a normal sleeping bag when the temperatures require it. So the baby or toddler is well protected even on cold days and can sleep in peace. The sleeping bag is made of 100% cotton jersey. The material has been tested for harmful substances and no optical brighteners have been used. The use of ribbons was also avoided in the production process to ensure maximum safety for the baby. A circumferential zipper facilitates diapering during the night. Towards the bottom, the sleeping bag becomes wider, so that the baby has plenty of freedom to romp around. The inner sleeping bag can be washed at 60 ° in the washing machine.
