Each layer may be inserted into, and removed from, the interior chamber individually. The components include a solid-state gel layer that stores thermal energy, a first radiant energy barrier that prevents the transfer of thermal energy radiating from an exterior of the gel-pack into the solid-state gel layer, and a second radiant energy barrier that reflects the thermal energy radiating from the user's body into the solid-state gel layer. ## Claims ### Claim 1 A multi-layer gel-pack for regulating a core body temperature of a user, the gel-pack comprising: a casing having a first surface configured to face towards a user and an opposing second surface configured to face away from the user; and a plurality of components disposed as layers within the casing and comprising: a thermal energy storage component configured to store thermal energy radiating from a user's body; a first radiant energy barrier disposed between the thermal energy storage component and the second surface of the casing, and configured to prevent the transfer of thermal energy radiating from an exterior of the casing into the thermal energy storage component; and a second radiant energy barrier disposed between the thermal energy storage component and the first radiant energy barrier, and configured to reflect the thermal energy radiating from the user's body into the thermal energy storage component; a first semi-solid gel component disposed between the first surface of the casing and the thermal energy storage component; and a second semi-solid gel component disposed between the first semi-solid gel component and the thermal energy storage component; and wherein each component is a stand-alone component configured to be inserted into the casing, and removed from the casing, independently of the other components. ### Claim 2 (depends on 1) The multi-layer gel-pack of claim 1 wherein the plurality of components further comprises a thermal insulation component disposed between the first and second radiant energy barriers, and wherein the thermal insulation component is configured to prevent the transfer of thermal energy that radiates through the first radiant energy barrier into the thermal energy storage component. ### Claim 3 (depends on 1) The multi-layer gel-pack of claim 1 wherein the first and second semi-solid gel components are configured to transfer the thermal energy radiating from the user's body into the thermal energy storage component. ### Claim 4 (depends on 1) The multi-layer gel-pack of claim 1 wherein one or both of the first and second semi-solid gel components are configured to store thermal energy radiated by the thermal energy storage layer. ### Claim 5 (depends on 1) The multi-layer gel-pack of claim 1 wherein the first semi-solid gel component is attached to an interior surface of the casing. ### Claim 6 (depends on 1) The multi-layer gel-pack of claim 1 wherein one or both of the first and second semi-solid gel components comprise a peripheral wall forming a recess configured to contain the semi-solid gel. ### Claim 7 (depends on 1) The multi-layer gel-pack of claim 1 wherein the first and second surfaces of the casing comprise, respectively, first and second shell layers affixed to each other at peripheral edges to form a pouch into which the plurality of components are removably disposed. ### Claim 8 (depends on 7) The multi-layer gel-pack of claim 7 wherein: the first shell layer is configured to be positioned nearest the user's body and to allow vapor molecules to move outwardly away from the user's body; and the second shell layer is configured to be positioned farthest from the user's body and to allow the vapor molecules to move outwardly away from an interior of the casing, and to prevent moisture from entering the casing. ### Claim 9 (depends on 7) The multi-layer gel-pack of claim 7 wherein the casing further comprises an opening formed by the first and second shell layers, and wherein the opening is configured such that selected components are inserted into the pouch, and removed from the pouch, through the opening. ### Claim 10 (depends on 1) The multi-layer gel-pack of claim 1 wherein the thermal energy storage component comprises a gel configured to store the thermal energy emitted by a user's body. ### Claim 11 (depends on 10) The multi-layer gel-pack of claim 10 wherein the thermal energy storage component comprises a plurality of individual compartments, with each compartment configured to hold a portion of the gel. ### Claim 12 (depends on 1) The multi-layer gel-pack of claim 1 wherein the second radiant energy barrier comprises a peripheral wall forming a recess sized to receive the thermal energy storage component, and is configured to focus the thermal energy radiated by the user's body into the thermal energy storage component. ### Claim 13 A multi-layer gel-pack for regulating a core body temperature of a user, the gel-pack comprising: a casing comprising an interior chamber formed between first and second exterior surfaces, wherein the first exterior surface is configured to face towards the user and wherein the second exterior surface is configured to face away from the user; a high thermal capacity (HTC) layer disposed within the interior chamber, wherein the HTC layer comprises one or more individual compartments with each compartment comprising a gel configured to store thermal energy radiated by the user's body; a first metallized reflective layer disposed within the interior chamber between the HTC layer and the casing, wherein the first metallized reflective layer reflects ambient thermal energy away from the HTC layer; a second metallized reflective layer disposed within the interior chamber between the HTC layer and the first metallized reflective layer, and configured to focus the thermal energy radiated by the user's body into the one or more individual compartments of the HTC layer; and first and second semi-solid gel layers disposed between the first exterior surface and the HTC layer. ### Claim 14 (depends on 13) The multi-layer gel-pack of claim 13 wherein one or more of the HTC layer, the first metallized reflective layer, and the second metallized reflective layer is a stand-alone component. ### Claim 15 (depends on 14) The multi-layer gel-pack of claim 14 wherein the one or more of the HTC layer, the first metallized reflective layer, and the second metallized reflective layer is configured to be inserted into, and removed from, the interior chamber by the user. ### Claim 16 (depends on 13) The multi-layer gel-pack of claim 13 wherein the second metallized reflective layer is configured to receive at least a portion of the HTC layer, and comprises a shape that focuses the thermal energy radiated by the user's body into the HTC layer. ### Claim 17 A method of assembling a multi-layer gel-pack for regulating a core body temperature of a user, the method comprising: inserting a thermal energy storage component into an interior of a casing, wherein the thermal energy storage component is configured to store thermal energy that radiates from the user; inserting a first radiant energy barrier into the interior of the casing between the thermal energy storage component and the casing, wherein the first radiant energy barrier prevents the transfer of ambient thermal energy into the thermal energy storage component; and inserting a second radiant energy barrier into the interior of the casing between the thermal energy storage component and the first radiant energy barrier, wherein the second radiant energy barrier reflects the thermal energy radiating from the user's into the thermal energy storage component; inserting first and second semi-solid gel layers between an exterior surface of the casing and the thermal energy storage component; and wherein each of the thermal energy storage component and the first and second radiant energy barriers are stand-alone components configured to be inserted into the interior of the casing independently of each other.
