An expandable and collapsible cooler includes: (a) a cooler wall defining an interior storage space of the cooler, the cooler wall including an inner collapsible wall and an outer collapsible wall each comprising a flexible elastomeric membrane that includes a plurality of hinge lines at which the membrane is configured to bend such that the membrane is transitional between a respective collapsed configuration and a respective expanded configuration by bending of the membrane along the hinge lines, each of the configurations corresponding to a stable configuration of the cooler; and (b) a bottom wall to which the collapsible inner and outer walls are joined and from which the collapsible inner and outer walls extend. The inner and outer collapsible walls define an intermediate space therebetween for insulating the interior storage space from an exterior of the cooler.
