A smoking article (2, 32, 34, 36, 38, 42, 56) comprises: a combustible heat source (4, 40)with opposed front and rear faces; an aerosol-forming substrate (6) downstream of the rear face of the combustible heat source (4, 40); an outer wrapper (12) circumscribing the aerosol- forming substrate and at least a rear portion of the combustible heat source;and one or more airflow pathways along which air may be drawn through the smoking article (2, 32, 34, 36, 38, 42, 56) for inhalation by a user. The combustible heat source (4, 40) is isolated from the one or more airflow pathways such that air drawn through the smoking article (2, 32, 34, 36, 38, 42, 56) along the one or more airflow pathways does not directly contact the combustible heat source (4, 40). |
