A method of making an insulated garment (1300, 1500, 1600), the method comprising: providing a first panel of material having a first surface area, wherein the first panel of material is defined by perimeter edges (1352, 1354, 1356, 1358); providing a second panel of material having a second surface area, wherein the first surface area is less than the second surface area; characterized by providing a section of thermally insulating fill material; positioning the section of thermally insulating fill material on the first panel of material; positioning the second panel of material such that the section of thermally insulating fill material is interposed between the first panel of material and the second panel of material; securing the first panel of material to the second panel of material at one or more areas adjacent to the section of thermally insulating fill material, wherein the first panel of material is secured to the second panel of material at a first seam and a second seam; wherein the securing step comprises applying an adhesive (1124, 1126) to an inner-facing surface of at least one of the first panel of material or the second panel of material at the one or more areas adjacent to the section of thermally insulating fill material, wherein the first seam is spaced apart from and unconnected to the second seam, the first seam corresponding to the second adhesive material and the second seam corresponding to the first adhesive material and defining an open-ended chamber containing the section of thermally insulating fill material; and forming the insulated garment (1300, 1500, 1600) using at least the first panel of material and the second panel of material, wherein when the insulated garment (1300, 1500, 1600) is formed, the first panel of material is positioned on an inner-facing surface of the insulated garment (1300, 1500, 1600). providing a first panel of material having a first surface area, wherein the first panel of material is defined by perimeter edges (1352, 1354, 1356, 1358); providing a second panel of material having a second surface area, wherein the first surface area is less than the second surface area; characterized by providing a section of thermally insulating fill material; positioning the section of thermally insulating fill material on the first panel of material; positioning the second panel of material such that the section of thermally insulating fill material is interposed between the first panel of material and the second panel of material; securing the first panel of material to the second panel of material at one or more areas adjacent to the section of thermally insulating fill material, wherein the first panel of material is secured to the second panel of material at a first seam and a second seam; wherein the securing step comprises applying an adhesive (1124, 1126) to an inner-facing surface of at least one of the first panel of material or the second panel of material at the one or more areas adjacent to the section of thermally insulating fill material, wherein the first seam is spaced apart from and unconnected to the second seam, the first seam corresponding to the second adhesive material and the second seam corresponding to the first adhesive material and defining an open-ended chamber containing the section of thermally insulating fill material; and forming the insulated garment (1300, 1500, 1600) using at least the first panel of material and the second panel of material, wherein when the insulated garment (1300, 1500, 1600) is formed, the first panel of material is positioned on an inner-facing surface of the insulated garment (1300, 1500, 1600).
