Patent number: 7716940Abstract: A garment for cooling the body of a wearer is described which comprises a substantially gas impermeable first substrate and a gas-permeable second substrate attached to form a cavity. At least one spacer element is provided between the first and second substrates to maintain gas flow in regions likely to be subjected to compression, e.g. by the body of a wear. At least one of the first and second substrates preferably comprises a plurality of raised protrusions on a surface within the cavity, and the gas permeable second substrate comprises a plurality of raised protrusions on the surface external to the cavity and proximate to the body of the wearer. The cavity is adapted to be connected to a gas supply such that the gas flows into the cavity and exits the cavity through the gas permeable second substrate. The cooling garment is light weight and conformable, and may be non-tethered for portability.Type: GrantFiled: February 3, 2006Date of Patent: May 18, 2010Assignee: Gore Enterprise Holdings, Inc.Inventors: Brian Farnworth, Paul Dacey
