1. A tubular collar, comprising:
a first sheet with a first curvilinear concave top, a first curvilinear convex bottom, and first and second tapered ends, the first sheet comprising an opening positioned between the first and second tapered ends, and the first sheet comprising a first fastener positioned on the first tapered end or the second tapered end, wherein the first and second tapered ends are tapered in a direction away from the opening; and
a second sheet with a second curvilinear concave top affixed to the first curvilinear concave top, a second curvilinear convex bottom affixed to the first curvilinear convex bottom, a third tapered end affixed to the first tapered end, and a fourth tapered end affixed to the second tapered end, a second fastener positioned on the third tapered end or the fourth tapered end, wherein the third and fourth tapered ends are tapered in a direction away from a mid-point of the second sheet,
wherein at across-section of the tubular collar where the first sheet is affixed to the second sheet, a length of the first sheet between the first curvilinear concave top and the first curvilinear convex bottom is greater than a length of the second sheet between the second curvilinear concave top and the second curvilinear convex bottom, thereby forming an enclosed cavity, wherein the opening provides access to the enclosed cavity through the first sheet, wherein the tubular collar is adapted to receive and maintain a heat transfer medium in the enclosed cavity via the opening, wherein a cross-sectional area of the enclosed cavity is tapered in a direction away from the opening,
wherein the first fastener is releasably attachable to the second fastener such that the tubular collar is configurable between an open configuration and a closed configuration, and wherein in the closed configuration, the first fastener is attached to the second fastener and the tubular collar forms a loop sized to be placed around the neck of an individual.
