1-30. (canceled)
An insulating garment apparatus comprising:
- a first liquid impermeable layer;
- a second liquid impermeable sheet overlaying and bonded to the first layer, the first and second layers forming a reservoir;
- a liquid composition comprising a halocarbon oil, an emulsifying agent, and a plurality of microcapsules;
- wherein the liquid composition is disposed between the first liquid impermeable layer and the second liquid impermeable layer.
A glove apparatus for providing insulation to a wearer, the glove comprising:
- an outer layer comprising a first and second surface;
- an inner layer comprising a third and fourth surface, the inner layer adapted to be oriented to the hand of the wearer, the inner layer being coupled in part to said outer layer;
- and
- a liquid composition disposed between the outer layer and the inner layer, the liquid composition comprising a halocarbon oil, an emulsifying agent, and a plurality of microcapsules.
A method for making an insulating garment, the method comprising:
- providing a first liquid impermeable layer;
- providing a second liquid impermeable layer;
- bonding the first layer and the second layer so as to form a reservoir;
- disposing a liquid composition in the reservoir, the liquid composition comprising a halocarbon oil, an emulsifying agent, and a plurality of microcapsules.
