A portable, adjustable, and flexible waist mounted, self-contained air distribution system for an individual which can distribute pressurized air over the upper or lower body of an individual, directly against the skin or the clothing of the individual, the system including a portable rechargeable battery operated blower fan in communication with a plenum and manifold, the manifold having a primary adjustable and flexible exhaust outlet openings that spreads, throws and disburses a pressurized air flow selectively over the upper or lower body of an individual, thereby allowing air to selectively provide a cooling and evaporate effect.

A spine cooling device is configured to hold the evaporative cooling textile in contact with a wearer's skin, particularly in a location between the wearer's hips and extending toward the wearer's tailbone. The spine cooling device has a pocket to hold the evaporative cooling textile, which textile can be periodically re-wetted while the spine cooling device remains in place on the wearer. The spine cooling device facilitates direct contact between the evaporative cooling textile and the wearer's skin, and is worn beneath the wearer's clothes. However, the device includes a water resistant layer placed to prevent the evaporative cooling textile from wetting the wearer's clothes.

The present invention is directed toward an article of apparel effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort.

An evaporator includes a housing with a first end and a longitudinally opposite second end, a hydrophobic membrane arranged within the housing fluidly coupling the first end of the housing to the second end of the housing, and a hydrophilic surface. The hydrophilic surface is arranged within the housing between the first end and the second end of the housing and is spaced apart from the hydrophobic membrane to draw liquid water away from the hydrophobic hollow fiber membrane. Spacesuits and environmental control methods are also described.

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.

A heat transfer system that may be used to absorb heat from a human user. A wearable vest is provided. The innermost surface of the vest is covered in hook-compatible material. One or more thermal transfer packs are configured to be attached to the vest. One or more hook panels on each thermal transfer pack is used to stick the thermal transfer pack directly to the innermost surface of the vest.

An article of apparel is described which is effective to regulate the temperature of the wearer. In an embodiment, the article of apparel includes a base textile with a thermal regulation membrane. The thermal regulation membrane contains a plurality of system-reactive components selectively engaged heat and/or moisture. In an embodiment, the printed coating includes a cooling agent, a phase change material, and a heat dissipation material. In operation, the article of apparel is effective to delay/diminish the rise in skin temperature (compared to a garment lacking the membrane), increasing wearer comfort.

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.

An item of clothing comprising an internal layer, made of vapor-permeable material, which faces the body of the user, an external layer, which is opposite with respect to the internal layer, a hybrid portion, which belongs at least partially to the internal layer and is located in the region of the collar of the item of clothing, and an interspace between the internal layer and the external layer. The item of clothing has at least one open region in the hybrid portion, the hybrid portion being at least partially not in contact with the body of the user.

A sports garment having a section covering the upper part of the body of a wearer during intended use of the garment, wherein a climate zone is arranged in the region covering each axillary area of the wearer during intended use. To improve the cooling of the axillary area efficiently, the climate zone has a plurality of fins which are arranged parallel to another and which are contacting the skin of the wearer during intended use of the garment, wherein the fins are extending along a defined height over a base material of the garment, wherein the fins are arranged in such a manner that the envelope of all fins has a kite-shape or rhomb-shape seen in the direction perpendicular onto the base material of the garment.
