b) at least one thermally conductive component,
i. wherein the at least one thermally conductive component is in temperature communication with the thermal reservoir and is positioned between the thermal reservoir and the skin,
ii. wherein the at least one thermally conductive component has at least a portion of its surface raised above a plane of the thermal reservoir and through a portion of an interior of the enclosure that forms an exterior surface of the portable thermal device,
iii. wherein the at least one thermally conductive component has an interior cavity created by a raised portion of the thermally conductive component that is filled with a substance capable of retaining or absorbing heat,
iv. wherein the at least one thermally conductive component has thermal conductivity of about 10 W/mK to about 250 W/mK;
v. wherein the at least one thermally conductive component has a width from about 5 millimeters to about 50 millimeters and a height from about 5 millimeters to about 50 millimeters; and
vi. wherein the at least one thermally conductive component provides a temperature change sensation and a massaging sensation when placed in close proximity to said skin.
2. A therapeutic device comprising a portable thermal device according to claim 1 and a wearable garment having at least one pocket for holding the portable thermal device.
3. The therapeutic device of claim 2 wherein the shape(s) of the pockets are substantially the same shape as the corresponding portable thermal device.
