A compact shoulder bag, padded with filling, which protects various objects from mechanical damage or keeps your electronics e.g. your cell phone warm inside on cold days: the air trapped in the filling delays the flow of heat to the outside, so that the warmth stays in the bag longer.
Due to the elastic cord attachment, the strap can move easily and adapts flexibly to the way you carry it, ensuring a comfortable fit without creases on the body but with direct force distribution.
