hello! my belly is filled with a pillow out of dinkel fur - you can take this pillow out with the zipper, warm it up in the oven or just keep it inside my belly. it will work like a very thick blanket and will warm very precise. my head and feet are filled with lambswool and my skin is made from cotton.
