The present invention relates to a cooling garment, comprising: a moisture-wicking under layer; and an impermeable outer layer, wherein the impermeable outer layer is attached to the moisture-wicking under layer forming at least one channel within the garment having a wetted perimeter of at most 5 inches; and an above ambient pressure gas supply operably attached to the channel. The present invention also relates to the cooling shirt or vest garment, comprising: a moisture-wicking under layer and an impermeable outer layer, wherein the outer layer is attached to the under layer forming a plurality of channels.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

A system for distributing garments at a point-of-use. The system includes a dispenser and a plurality of substantially planar sheets each comprising an individual garment disposed within and configured to be dispensed from the dispenser. Each garment includes a torso; first and second sleeves extending from the torso; a pocket disposed on a front portion of the torso; and a through-hole disposed in the pocket and configured to receive a wire therethrough.

A device for cooling the surface of an object or the skin of a person or animal comprising a plurality of evaporator fins, each having a substantially planar horizontal portion for making contact with an object to be cooled, one or more vertical portions attached to or continuing from the horizontal portion that extends upward there from, and a fabric layer disposed on a surface of the vertical portion. The device includes a support member comprised of one or more parts that connect the plurality of evaporator fins into a larger structure, and can include means to urge the horizontal portions of the evaporator fin assembly against a surface to be cooled. The device can also be embodied as one or more pieces of fabric with a plurality of convoluted evaporator fins adhered to it.

A system may include an article of apparel and a fluid source. The article of apparel incorporates a plurality of fluid channels, and the apparel includes a fluid connector in fluid communication with the fluid channels. A fluid source is configured to join with the fluid connector and supply a fluid to the fluid channels. The article of apparel may include a pad component formed from a polymer foam material, which defines the fluid channels. A pair of material elements may be secured to opposite sides of the pad component, with one of the material elements being fluid permeable adjacent to at least a portion of the fluid channels.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

A cooling garment includes a front side material and a back side material arranged on a front side or a back side of a body. The front side material or the back side material has an inner layer arranged closest to the body that is waterproof, an outer layer arranged farthest from the body that is moisture permeable and an intermediate layer made of a nonwoven fabric arranged between the inner layer and the outer layer and that absorbs water and stores the absorbed water. A water inlet that supplies the water to the intermediate layer is arranged at an upper part of the front side material or the back side material and a drainage outlet that drains the water is arranged at a lower part of the front side material or the back side material when the cooling garment is attached to the body.

An article of apparel is formed that is effective to regulate the temperature of the wearer. In an embodiment, a thermal regulation composition is obtained comprising a binder, a cooling agent, a latent heat agent, and a heat dissipation agent. The thermal regulation composition is printed to a surface of a textile by pressing the thermal regulation composition against the textile surface such that the binder adheres the cooling agent, latent heat agent, and the heat dissipation agent to the surface of the textile, thereby forming a thermal regulation membrane, and the textile is incorporated into an article of apparel.

Described herein is a perspiration evaporation device (PED) utilizing an evaporative column having an internal channel that can be secured to a garment or other accessory. As air passes over the top opening internal channel the internal air pressure within the evaporative column is reduced causing evaporated moisture from a user's skin to be drawn up the internal channel and away from the skin resulting in improved evaporation of moisture and a reduction in the core body temperature of a user.

A cooling garment includes a front side material and a back side material arranged on a front side or a back side of a body. The front side material or the back side material has an inner layer arranged closest to the body that is waterproof, an outer layer arranged farthest from the body that is moisture permeable and an intermediate layer made of a nonwoven fabric arranged between the inner layer and the outer layer and that absorbs water and stores the absorbed water. A water inlet that supplies the water to the intermediate layer is arranged at an upper part of the front side material or the back side material and a drainage outlet that drains the water is arranged at a lower part of the front side material or the back side material when the cooling garment is attached to the body.
