a mouth end portion; and
an aerosol generating cartridge in fluid communication with the mouth end portion, and
comprising:
an enclosure configured to receive an aerosol precursor therein, the aerosol precursor being configured to generate an aerosol in response to heat, at least a portion of the enclosure being permeable such that the aerosol precursor is retained within the enclosure while the aerosol formed from the aerosol precursor is released from the enclosure through the permeable portion upon heating of the enclosure or the aerosol precursor therein, the enclosure further defining first and second end wall portions, wherein the second end wall portion is inset relative to the first end wall portion so as to define two or more pockets that are recessed with respect to an end plane of the cartridge, each pocket defining a void space that creates a convective air gap, wherein each of the two or more recessed pockets is positioned adjacent a first end wall portion.
