A portable insulated container is formed of an inner shell and an outer shell connected together to form the container with a space between the inner shell and the outer shell for an insulting material. An insulation material fills at least a part of the space between the inner and outer shells with at least part of the outer shell being formed of a transparent material so that the insulation material in the space is visible through the outer shell. The insulation material is formed of a naturally occurring material such as straw or a recycled material such as paper, the nature of which can be visibly determined by viewing of the insulation material in the space through the outer shell.
