A cooling garment cooling device includes: a water delivery hose with a cooling water supply portion and cooling water branch portion; a pump supplying cooling water from the cooling water supply portion toward the cooling water branch portion; and plural branched water hoses having a first end-side water supply portion and second end-side water supply portion coupled to the cooling water branch portion. A portion of the branched water hoses between the first end-side water supply portion and second end-side water supply portion serves as a water outlet portion. Each branched water hose diameter is smaller than the water delivery hose diameter. The outer peripheral portion of the water outlet portion of each branched water hose orthogonal to the longitudinal direction of the branched water hose has plural water passage holes with opening areas smaller than those of the first end-side water supply portion and second end-side water supply portion.

Portable body cooling apparatus, particularly wearable on subjects, the apparatus comprises a channeled assembly including a coupled pair of channels longitudinally extending adjacent to each other, and wearable along outer contour of a subject's body part. The apparatus also comprises a forced air flow assembly connected to channeled assembly, for generating and driving forced flow of air into and through channeled assembly and facilitate indirect evaporation of liquid inside the channeled assembly, so as to produce forced flow of cool air exiting from channeled assembly and directed onto the subject, thereby cooling the subject. Also disclosed is a corresponding method of cooling a subject.

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.

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 headgear is disclosed. Absorbent material within the headgear retains cold water. When worn by a user, the headgear holds the cold water to the head of the user, cooling the user.

An evaporative cooling garment includes a first layer and a second layer superimposed over the first layer. The first layer is configured to absorb a quantity of water, and the second layer includes a reflective material and defines openings. The first layer is visible from an exterior of the garment through the openings in the second layer, and the garment defines a collapsible gap between an inner surface of the second layer and an outer surface of the first layer.

An article of apparel is formed that is effective to regulate the temperature of the wearer. In an embodiment, a thermal regulation composition is applied to a surface of a textile substrate at a first temperature and a first pressure to form a thermal regulation membrane disposed on the surface of the textile substrate. The textile substrate with the thermal regulation membrane is compressed at a second pressure and a second temperature to position a portion of the thermal regulation membrane below the surface of the textile substrate. The textile substrate is incorporated into an article of apparel. The thermal regulation composition can include one or more system reactive components provided within a binder, where a system reactive components can include a cooling agent, a latent heat agent and/or a heat dissipation agent.

Various exemplary embodiments relate to a business suit. The business suit includes front facing panels and upper sleeve panels formed of a first facing fabric; and an inner lining formed of a second moisture wicking fabric. The suit may further include exterior back panels or lower sleeve panels formed of the second moisture wicking fabric. The suit may further include a sleeve liner interior to a respective upper sleeve panel and the lower sleeve panel, the sleeve liner formed of a third fabric. In various embodiments, the business suit further includes pants. The pants include exterior facing panels formed of the first facing fabric; a waistband formed of the first facing fabric; and a pants liner formed of the second moisture wicking fabric and joined to the waistband. The pants may further include an exterior crotch insert panel formed of the second moisture wicking fabric.

An article of apparel is formed that is effective to regulate the temperature of the wearer. In an embodiment, a textile substrate is obtained, and a thermal regulation composition is applied to a surface of the textile substrate at a first temperature and a first pressure to form a coated textile substrate. The coated textile substrate is dried to form a thermal regulation membrane disposed on the surface of the textile substrate, and the textile substrate with the thermal regulation membrane is compressed at a second pressure and a second temperature to position a portion of the thermal regulation membrane below the surface of the textile substrate. The textile substrate is incorporated into an article of apparel. The thermal regulation composition can include one or more system reactive components provided within a binder, where a system reactive components can include a cooling agent, a latent heat agent and/or a heat dissipation agent.

A wearable device, such as a garment or containing garment portions, for managing and/or reducing the symptoms of a hot flash in a subject. The device comprises: a first set of components, each comprising a fabric comprising a cooling yarn; a second set of components, each comprising a quick-dry wicking fabric; and a third set of components, each comprising a phase change material fabric, wherein the first set of components are adapted to cover at least a neckline region and a peripheral region that extends adjacently around the armpit and the clavicle of the subject; the second set of components are adapted to cover at least the abdominal muscles and the lumbar regions of the subject; and the third set of components are adapted to cover at least the mammary and the dorsum regions of the subject.
