Abstract
A double-structure headwear and a manufacturing method thereof may provide improved productivity by easily forming the double-structure headwear and provide a shielding effect against external heat and wearing comfort. The double-structure headwear includes a first wearing portion, and a second wearing portion being disposed on an inner side of the first wearing portion. The first and second wearing portions have each lower portion sewed and folded to a predetermined height in a vertical direction, and the first wearing portion has a lower thermal conductivity and lower contact thermal sensation than that of the second wearing portion.
