Abstract: A thermally protective composite material is provided, which can be used in making garments. The thermally protective composite material includes an outer layer of fabric/textile, an adhesive layer applied to the outer layer of fabric in a geometric pattern, and an elastic inner layer of fabric/textile, adhered in a stretched state, to the outer layer via the adhesive layer. The elastic inner layer, when in a relaxed state, causes the adhered outer layer to vault/bubble forming raised cavities according to the geometric pattern of the adhesive. When constructed into garments the thermally protective composite material can stretch between the relaxed state and the stretched state of the elastic inner layer.
