Insulated shipping container systems, kits and methods

A containment sleeve comprising:

• a sleeve configured in size and shape to separate a payload container from inside walls of an insulated shipping container;
• said insulated shipping container being configured to receive the payload container therein;
• wherein the payload container is configured in size and shape such that said payload container may be positioned within and spaced from inside sidewalls of the insulated shipping container,
• wherein the sleeve is configured to be positioned around and spaced away from outer walls of the payload container;
• and
• wherein the sleeve is further configured to allow airflow between inside walls of the insulated shipping container and outer walls of the containment sleeve such that air is free to flow between outside sidewalls of the payload container and the inside sidewalls of the insulated shipping container.

A container, comprising:

• a container body having an inner wall configured and arranged to receive a payload and a heat transfer element therein;
• a containment sleeve configured and arranged to space the payload from the inner wall thereby defining an air-filled space between the payload and the inner wall over a portion of a surface area of the payload;
• and
• a spacer configured and arranged to space the heat transfer element from the inner wall thereby defining an air-filled space between the heat transfer element and the inner wall over a portion of a surf ace area of the heat transfer element;
• the air-filled space between the inner wall and the payload surface area and the air-filled space between the inner wall and the heat transfer element surface area in fluid communication to facilitate heat transfer therethrough.
