A sleeve for a garment, comprising: a front panel attached to a back panel along respective first and second side edges thereof, the back panel having upper and lower vents formed proximate an elbow portion thereof; and, upper and lower flaps formed on the back panel above and overlapping the upper and lower vents, respectively; wherein the upper and lower flaps are moveable between a closed position when the sleeve is straight through the elbow portion and an opened position when the sleeve is bent at the elbow portion to thereby allow increased airflow through the upper and lower vents when the garment is in use.

Aspects herein are directed to an article of apparel having a vent opening formed by overlapping the edges of a first panel and a second panel. A plurality of discrete overlay film structures are applied to the second panel adjacent to the vent opening. When the article of apparel is exposed to an external stimulus, the film structures undergo a reversible increase in dimension in at least the z-direction which cause the second panel of material to undergo a reversible decrease in dimension in the direction of a longitudinal axis of the vent opening thereby causing the vent opening to dynamically transition from a closed state to an open state.

A multi-function clothes structure mainly includes a body portion having a sleeve respectively configured on two sides thereof, one end of the body portion being in connection with a cap, and an opening being configured on one side of the cap and a covering body being in connection with an inner side thereof. Furthermore, one side of the body portion is configured with at least one pocket extended from one face of the body portion to another face thereof, and a ventilation portion is configured on the connection of the body portion and sleeves. Whereby, the prevent invention can achieve the effects of ventilation, warm keeping, mouth and nose covering and placement convenience of an item.

A bimorph meta fiber is formed through spinning of two antagonistic polymer melts, one of which contains pre-compounded optical nanostructures, into an eccentric sheath-core configuration or a side-by-side key-lock configuration. The bimorph meta fiber is capable of an adaptive regulation of the infrared radiation responsive to humidity level deviation from a comfort zone or perspiration level of the wearer of the garment fabricated from the meta fibers. The bimorph meta fibers are humidity/heat trained to attain dynamical environmentally responsive behavior to maintain the humidity/thermal comfort zone at various the humidity level fluctuations.

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.

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 adaptive article of apparel can include a textile with an opening that is configured to admit a body part of a wearer, and an electroadhesive clutch secured to the textile and extending around at least a portion of the opening. The electroadhesive clutch can be configured to permit or inhibit changing a size of the opening.

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.

A jacket includes a main jacket body and an active heating system. The main jacket body is adapted for covering at least part of the body of a user, and has a neck section adapted to be disposed proximate to the neck of the user, a waist section adapted to be disposed proximate to the waist and lower back of the user, and at least one abdomen section adapted to be disposed proximate to the abdomen of the user. The active heating system is disposed in the main jacket body, is adapted for generating and transferring heat to the user, and includes at least three heating units. Each of the heating units is disposed in a respective one of the neck section, the waist section and the abdomen section of the main jacket body.

Aspects herein are directed to an apparel item that promotes thermo-regulation through the use of engineered openings, venting, and/or stand-off structures. In exemplary aspects, 20-45% of the apparel item may comprise the engineered openings. Vents may be positioned on the apparel item in areas that experience high amounts of air flow to help channel air into the apparel item. The stand-off structures may be positioned on an inner-facing surface of the apparel item where they help to create a space between the apparel item and the wearer's body surface in which air can flow and help cool the wearer by promoting evaporative cooling.
