The use of select knitting processes allow the production of a cap liner with a separate eye opening and several distinct mesh structures that are individually designed to enhance the comfort of the eyes, nose, and mouth of the wearer. Generally, the cap liner comprises: (a) a cap body comprising an upper mesh structure; (b) a neck retainer that is integrally formed with the cap body; (c) an eye opening positioned in the cap body; (d) a first ear position positioned in the cap body comprising a second mesh structure; (e) a second ear position positioned in the cap body comprising a third mesh structure; (f) a nasal ventilation positioned in the cap body comprising a fourth mesh structure; (g) a mouth ventilation positioned in the cap body comprising the fourth mesh structure or a fifth mesh structure; (h) a neck retainer base positioned on the neck retainer that is integrally formed with the neck retainer and comprises a sixth mesh structure or a two-layered structure; and (i) an edging at least partially surrounding the eye opening that comprises a three-layered structure.

A disposable protective garment for positioning over a wearer's head is provided for use in airplanes, busses, trains, other mass transit and other single-use applications. The disposable protective garment includes a hood formed of tubular blown film that has an at least partly closed top that rests on a wearer's head and an open bottom that rests on a wearer's shoulders. A mask can be integrated into the hood by forming a plurality of apertures in the hood and placing a polymer fabric that acts as a filter over the plurality of apertures. The hood may alternatively be combined with a crown or air filter material positioned over its top; a tubular filter equipped with an electric fan that draws air from above, filters it and directs the clean air downward across the wearer's face; and/or headgear. A barrier film suitable for use in the protective garment as well as other barrier applications is also provided.

A personal sterilization system, including a base unit defining an air intake, a fan, and a fluid path from the air intake to the fan; at least one UVC light source positioned to illuminate at least a portion of the fluid path with UVC light; a delivery conduit attached to the base unit in fluid communication with the fan; and a dispersion device configured to be worn in proximity to a person's face, the dispersion device defining a fluid inlet attached to the delivery conduit, and at least one fluid outlet configured to disperse pressurized air.

The present invention relates to a ventilation insert or liner for headwear. The ventilation insert or liner is comprised of a top edge, bottom edge, a backside extending between the top edge and bottom edge, and a front side opposite the backside. The front side has at least one ventilation structure, such as a tube, extending between the top edge and the bottom edge that increases air flow (i.e., ventilation) from a cool area (e.g. below the brim of a hat) to the inside of the headwear. The ventilation insert or liner may comprise a plurality of ventilation structures. The plurality of ventilation structures may comprise a plurality of apertures to increase air flow. The back side may comprise a connection material to affix the vent insert or liner to the inside of the headwear. The ventilation insert or liner may alternatively be inserted into a sweatband found on the inside of most hats.

A cooling headgear is disclosed. Absorbent material within the headgear retains cold water. When worn by a user, the headgear holds the cold water to the head of the user, cooling the user.

A cap ventilation system and a cap including the system are provided. The cap ventilation system includes at least one spacer that when fixed to an interior or a brim of the cap, creates a gap between the interior or brim of the cap and the head of the user. If desired, a plurality of spacers may be spaced about the circumference of the interior or brim to extend the gap about the circumference of the interior or brim.
