1. A cartridge for a vapor provision system, comprising:
a reservoir for aerosolizable substrate material, the reservoir defined by a housing;
an atomizer for aerosolizing the aerosolizable substrate material from the reservoir, the atomizer located externally to outer dimensions of the reservoir; and
an enclosure at least partially surrounding the atomizer to define an aerosol chamber around the atomizer, the enclosure comprising:
at least one wall defining the aerosol chamber, the at least one wall including a side wall defining a central space that creates the aerosol chamber outside the outer dimensions of the reservoir;
a joining portion by which the enclosure is coupled to the housing so as to extend outwardly from the housing;
an opening in the at least one wall to allow aerosolizable substrate material to enter the aerosol chamber from the reservoir and aerosol to exit the aerosol chamber; and
one or more apertures in the at least one wall to allow air to enter the aerosol chamber.
