A configurable storage container system for storing items includes a tote, an insulated shell with a lid, and an insulated divider configured to divide the internal cavity of the tote into two sections. The insulated shell is configured for receiving the tote. The insulated shell includes a base and a plurality of side walls and is foldable between an expanded configuration and a collapsed configuration such that the tote fits inside the insulated shell when the insulated shell is in the expanded configuration. The lid is configured for closing the tote inside the insulated shell when the insulated shell is in the expanded configuration.
