A device for warming a first arm and shoulder of a wearer includes a single arm portion and a torso portion. The single arm portion is configured to substantially cover the first arm of the wearer from the shoulder to a position beyond an elbow of the first arm. The torso portion is connected to the single arm portion.

An article of apparel is disclosed that includes zones with a textile having a structure than changes or is otherwise modified by a physical stimulus, such as the presence of water or a temperature change, to modify a property of the textile. The zones may be along a center back area and/or side areas of the apparel, and the textile may increase in air permeability when exposed to water. In some embodiments, slits are formed in the textile.

An article of apparel can include or use an electroadhesive clutch device. The device can include an elongate encasing for a first electrode assembly and a second electrode assembly each having a respective first and second electrode. The first and second electrodes can be at least partially overlapping and configured to slide or move relative to each other. The device can include an electrical signal generator configured to provide first and second signals to the first and second electrode assemblies, respectively, wherein the first electrode assembly is configured to slide laterally relative to the second electrode assembly when the first and second signals are not applied, and is configured to remain static relative to the second electrode assembly when the first and second signals are applied. The apparel can include a textile material to which the encasing is attached at least at a first end of the encasing.

An article of apparel can include an aperture. An electroadhesive clutch device can be coupled to, or integrated with, the article of apparel, and the clutch device can be configured to selectively open and close the aperture. An electric signal generator can be coupled to the clutch device and configured to provide one or more signals to the clutch device to thereby open or close the aperture.

An opening section adjustment mechanism adjusts an opening area of an opening section through which a rope is passed. The opening section adjustment mechanism includes an opening creation mechanism that leaves an opening section around the rope passed through the opening section even when the opening area of the opening section is adjusted to the minimum.

The present disclosure provides a breathable structure, a breathable fabric and garments, wherein the breathable structure comprises a first protection module and a second protection module configured to fit with the same along a length direction; any one of the protection modules comprises at least one protection unit, and when there are a plurality of protection units, each of the protection units is arranged along a width direction; any one of the protection units is of an arched sheet structure, and the arching height of the sheet structure decreases along the length direction; one end of the second protection unit extends below the first protection unit along the length direction so as to establish a fit between the first protection module and the second protection module; a breathable channel is formed through between the first protection unit and the second protection unit.

Aspects herein are directed to an apparel layer system configured to provide variable levels of insulation, warming, or air permeability. The apparel layer system comprises a first layer of material and a second layer of material both extending in a first planar direction. A third layer of material is positioned between the first and the second layers of material and is selectively affixed thereto. An adjustment mechanism coupled to the second layer of material can be mechanically manipulated to shift the second layer of material between different positions or states to achieve variable levels of offset between the first and second layers of material in the first planar direction and in a second direction perpendicular to the first planar direction.

A preparation method of a garment with automatic opening, includes: firstly, a garment opening preform is manufactured, and then an automatic opening garment is prepared by using the preform. In the preform, one or more functional layers with predetermined shapes and sizes are connected to the positioning layer; when the clothing needs to be opened, the preform only needs to be connected with the area to be opened of the clothing, and the incision is made according to the position of the functional layers, so that the positioning is not required by a pair of incisions on the clothing, which is efficient, convenient, concise and easy to adjust, and provides a convenient and accurate template function for the opening of the clothing, namely, opening and using. The functional layer of the garment opening preform is made of hydrophilic material or hydrophobic material.

An electrode device for an electroadhesive clutch can include a planar conductive member and a housing that encloses at least a portion of the conductive member. In an example, the housing can include a flexible polymeric substrate provided adjacent to at least a first surface of the conductive member, and a dielectric member comprising a first portion provided adjacent to an opposite second surface of the conductive member, and a second portion provided adjacent to a first side edge of the conducive member and coupled to the flexible polymeric substrate.
