Abstract
The present invention provides a body cooling garment to easily and effectively protect the human body in hot conditions. By suspending in vapor contact a cold surface with channels in it'"'"'s surface; moisture is evaporated from the body, condensed on the cold surface, and the body shielded from environmental heat. The condensed moisture is channeled from the garment.

5. A garment for cooling the body of a wearer fashioned of layered components into a generally rectangular garment having opposite end edges and opposite side edges, said garment having a head opening in a generally central location for accommodating head and neck of said wearer, front and rear panels, defined by said head opening, for overlaying chest and back of said wearer respectively, said garment having an inside surface being the surface closest to the body of said wearer, said front and rear panels comprising layers, presented here in an order starting with the claimed layer closest to said inside surface as follows:
- a spacer layer of a vapor permeable hydrophobic material on the inside of a heat absorbing layer having a temperature below the dew point of water with a substantially unrestricted vapor travel between the wearer and the heat absorbing layer.
