A fabric structure includes a first layer, which is breathable and adapted to be directed toward the body of the user, a second layer, which has preferential passages for sweat in the vapor phase leading outward from the first layer, a third layer, which is breathable and arranged opposite the first layer, the second layer being between the first layer and the third layer. The first layer includes fibers of heat-conducting material.

A cooling garment including an article of clothing; and a cooling system associated with the article of clothing, which includes (a) a fabric portion incorporated into or integrated within the article of clothing; and (b) a fluid supply and dispensing apparatus for supplying and dispensing fluid to the fabric portion. The apparatus includes (i) at least one fluid bladder for holding fluid; (ii) a fluid pumping mechanism; and (iii) tubing having a tubing outlet for conveying fluid from the bladder and dispensing the fluid from the tubing outlet to the fabric portion. The clothing is configured to hold the fabric portion snugly to the body of the wearer and the fabric portion is disposed adjacent at least one superficial blood vessel so as to dispense the fluid specifically to the fabric portion adjacent the at least one superficial blood vessel and not to other areas of the clothing.

The invention relates to a cooling garment for cooling a torso of a wearer, comprising a front and a rear panel with a neck opening therebetween, wherein the front panel and the rear panel together comprise one single cooling section composed of two outer layers with a water absorbent layer sandwiched therebetween. The two outer layers are sealed together along their edges to form a single compartment for the storage of water, wherein the portions of the compartment that are at the front and the rear panel are in fluid communication with one another over the shoulders. Both outer layers are impermeable to water but permeable to water vapor. The cooling garment may be activated by filling the compartment with water via an inlet in one of the outer layers.

A wearable garment comprising a customizable and reusable top and a bottom portion are disclosed. The top portion comprises a vest for an upper part and the bottom portion comprises a short for lower part of the body. Both the portions are attached to each other using a plurality of straps which comprise of pouches filled with a phase change material and are in direct contact with the body. The top and bottom portions of the wearable garment have equally divided sheets or pouches to prevent leakage of energy from the body and maintain body temperature for extended working hours. The phase change material can be eutectic ice or humps fat to cool/heat the body by dissipating/absorbing the heat generated by the body. The top and bottom portions and the straps are immersed in a mixture material comprising of a mixture of hydrocarbon chain, water and a salted base.

The present disclosure generally relates to intelligent garments that provide thermal regulation in a variety of environments. The garments may include different layers such as a hydrophobic layer in direct contact with a wearer's skin surface and saturated with an aqueous mixture, a spacer layer, a reflective layer, and an outer hydrophobic layer. The layers of the garment may work together to reduce the metabolic expenditure of the wearer in extreme environmental conditions or during demanding physical activity. A variety of sensors may be displaced throughout the garments so as to enable the collection of data associated with wearers as well as environmental conditions. Wearers may control the thermal balance and other properties of the garments as desired.

The invention relates to a multi-layered fabric comprising an absorption layer between two liquid-permeable layers, which multi-layered fabric has a surface with: 1) one or more connection areas wherein a connection is present between both layers; and 2) one or more absorption areas wherein both layers are not connected to each other. The absorption areas are capable of absorbing a liquid whereby the liquid is absorbed by the absorption layer. The connection between the layer L1 and the layer L2 comprises a fusion of the layer L1 and the layer L2, which fusion optionally also includes the absorption layer.

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.

The present invention comprises a heat transfer vest. The vest is configured to mount a plurality of heat transfer packs on its interior surface. In the preferred embodiments the appropriate portions of the interior surface are covered in a hook-compatible material. In these versions, the thermal transfer packs include one or more hook panels that are used to attach the packs to the interior surface.

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.
