A ventilation device including a flexible support having first and second edges delimiting a longitudinal opening and being provided with first and second closing devices arranged to cooperate with one another, the ventilation device including at least one elastic spacer member which includes a first tab extending along the first edge and a second tab extending along the second edge, the elastic spacer member being constrained when the closing devices are in the closed position, so that the first and second tabs tend to separate from one another, the length of at least the first tab being less than half the length of the first edge.

To pump-condition a garment that covers at least a portion of an individual, at least one fluid-circulating vent panel circulates a fluid adjacent the garment in an effort to condition the individual. A pump provides a motive force to circulate the circulating fluid through each vent panel. A circulation layer within the vent panel defines a plurality of channels therethrough. The channels allow the circulating fluid to pass both laterally through an opening in a peripheral edge of the vent panel and directly through a diffusing layer of the vent panel.

A personal protective device (PPE) including a face cover assembly and a bodysuit configured to be worn by a human user. The device protects users against airborne aerosol particles containing viruses or other infectious agents while enabling improved flexibility relative to prior art designs. The device includes a helmet-like” rotating face cover assembly that fits over the user's head and attaches to a collar on the biohazard bodysuit. This rotating face cover assembly has a plurality of different mask sides, each with differing geometries or other properties. The device enables a user to rotate (either manually or by electric motor) the masks and select a given mask side that best meets that user's needs. The different mask sides can accommodate different facial geometries, eyewear types, and use cases, such as operation in more hostile environments. Features to improve user comfort, including alternate bodysuit designs, moisture reduction, and cooling are disclosed.

Aspects herein are directed to systems, methods, and articles for producing a patterned film and using the patterned film to form a pattern of discrete overlay film structures on a substrate material. A uniform thickness of a film material is deposited on to a first surface of a run of carrier sheets, where each carrier sheet includes one or more holes extending there through. A first carrier sheet is extracted from the run of carrier sheets, and a second surface of the carrier sheet is positioned on a substrate material. Heat and/or pressure is applied to the film material to cause the film material to transfer to the substrate material through the one or more holes in the carrier sheet forming a pattern of discrete overlay film structures on the substrate material. The carrier sheet along with remaining portions of the film material is removed from the substrate material.

A neck warmer with adjustable function comprises a warmer body with first opening and second opening; and a first ear accommodating hole and a second ear accommodating hole, which can be hung on the ear so that the warmer body adopts single-layer waring form, or fold the warmer body in half, hang the first and second ear accommodating holes on the ears, so that the warmer body adopts a double-layer wearing form. The warmer body is made of seamless and comfortable high-stretch fabric. A certain number of ear accommodating holes are formed on both sides and middle of the warmer body. In order to cope with the external environment including air temperature and severe haze weather, the warmer body adopts a design structure that can be worn in a single layer or folded in half to form a double-layer structure, so as to achieve the purpose of multi-layer protection.

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.

The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to garments with chambers to retain an insulating fill material. Openings along seams between the insulating chambers may achieve evaporative moisture or air transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment. In an aspect, the garments comprise one or more insulated zones provided with one or more vented-insulation sections provided at locations on the garment configured to align with one or more areas of a wearer's body that are more sensitive to environmental conditions (e.g. temperature) and/or are prone to faster heat loss.
