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.

Articles and methods of using and making adaptive garment portions are provided. An adaptive garment portion is one that has shifting surfaces with apertures that shift from an aligned to an offset orientation depending on environmental conditions/stimuli. For example, a first surface material and a second surface material may be coupled by a responsive material portion. The responsive material portion may physically change in response to a change in environmental conditions internal or external to the garment (e.g., thermal energy, moisture) and/or stimuli (e.g., light energy, electrical energy, magnetic fields). The physical change in the responsive material portion facilitates the planar shift of the first surface material relative to the second surface material.

The technology described herein relates to vented and insulating garments having an interior garment assembly comprising an interior panel and a middle panel attached at one or more seams defining chambers for retaining thermally-insulating fill material. The seams have a first plurality of openings extending through the interior and middle panels. An exterior garment assembly has a second plurality of openings positioned on the exterior garment assembly such that the second plurality of openings are offset from the first plurality of openings when the exterior garment assembly is worn with the interior garment assembly. The offsetting of the openings may achieve moisture vapor or air transfer from the inside of the garment to the outside environment. The exterior garment assembly and the interior garment assembly may be discrete garment pieces or may be attached at one or more locations.

A vapor-permeable insert for item of clothing or accessory, including a collector element adapted to absorb solar radiation, a window element that is transparent to the solar radiation absorbed by the collector element, and an interspace formed between the window element and the collector element, the collector element and the window element being arranged at two opposite faces of the interspace.

A ventilation apparatus includes a motor, a fan, a housing, and a ring. A projection protrudes from one of an outer peripheral surface of a peripheral wall part of the housing and an inner peripheral surface of the ring, whereas an engagement wall and a guide wall are provided on the other of the outer peripheral surface of the peripheral wall part of the housing and the inner peripheral surface of the ring. The guide wall has a guide surface configured to guide the ring rearward relative to the housing and to guide the projection to an engagement position at which the projection is abuttable on an engagement surface of the engagement wall. In a direction in which the projection moves away from the guide surface in a front-rear direction, an open space extends from the guide surface to an area that corresponds to an end of the second surface.

Leggings with a crotch gusset assembly and inner thigh mesh panels are provided. Leggings having a crotch gusset assembly, may include a first leg for receiving a user's first leg; a second leg for receiving a user's second leg; a first inner thigh mesh panel and a second inner thigh mesh panel for providing ventilation; and a crotch gusset assembly having at least one inside gusset panel and an outer gusset panel, wherein the at least one inside gusset panel and the outer gusset panel are attached to form a pocket for retaining a removable absorbent pad.
