1. A garment comprising:
a main body configured to cover at least a portion of a body of a wearer of the garment; and
a heat insulation material (i) configured to cover at least a part of the portion of the body and (ii) having a known insulating capability,
wherein:
the main body includes (i) an outer fabric having an attachment hole configured to receive and retain a blower device and (ii) an inner fabric attached to an inner surface of the outer fabric along an edge part of the inner fabric;
the main body is configured such that the inner fabric is closer to the body of the wearer than the outer fabric when the garment is worn by the wearer;
an internal space is defined by the outer fabric, the inner fabric and the edge part of the inner fabric;
the internal space is configured such that, when the blower device is attached to the garment and operating, the internal space (i) receives air from an outlet of the blower and (ii) allows the air to flow throughout the internal space;
the heat insulation material is a separate member from the outer fabric and the inner fabric;
the main body and the heat insulation material are configured such that the heat insulation material is removably attachable to the main body in the internal space; and
the heat insulation material has a positioning part configured to (i) be received through the attachment hole and (ii) engage the outer fabric adjacent to the attachment hole to hold the heat insulation material at a predetermined position relative to the main body.
