Abstract: Head cooling aid device comprises a strip of flexible material having a series of laterally spaced air flow passageways extending completely through the width of the strip for allowing air to flow through the passageways. At the approximate center of the length of the device is an inwardly facing recess or cavity that substantially spans the space between the wearer's eyes to avoid the pinching-off of blood flow to the wearer's head in this region caused by tight cap headbands resulting in poor blood circulation in this region that may cause over-heating of the head and/or excess sweating. The device can either be attached to an inner surface of a front portion of a cap headband or be made an integral part of the front portion of the cap headband to promote air flow into the cap through the passageways and out through top vents in the cap when worn to contribute to cooling of the top of the wearer's head.

Abstract: A hat suitable for use in outdoor applications is provided. The hat provides protection from the elements, e.g., rain, wind, sun, while used in outdoor activities, such as hiking, while also providing enhanced ventilation features so that the hat may regulate heat that is either absorbed by the hat or generated by the head of the user.

Abstract: The present invention is related to a 3D ventilation device for separating body skin from clothes including an elastic meshed fabric, an elastic framework and a fixing device, wherein the 3D elastic framework which supports and holds the elastic meshed fabric, is fixed by the fixing device to locate between the skin and the clothes, so as to form a ventilative chamber for achieving the separation. Here, the elastic framework can be bent to adapt to different body shapes or portions and adjusted to provide most comfortable wearing angle, so that a proper air flowing can be achieved between the skin or the body portion and the clothes, thereby keeping the skin dry.

Abstract: Disclosed is an apparatus and related methods for adjustable shading.

Abstract: A non-fabric head or body band is made from compressed cellulose pop-up sponge material for cooling the wearer. The band comprises a reversible strip of pop-up sponge material in which one or more holes or passageways are formed, the ends of which are connected by an elastic band. The band is wetted causing the pop-up sponge material to expand, such that the inner and outer surfaces are approximately ?th of an inch apart, between which is held a supply of water/liquid. The inner surface is substantially in contact with the wearer, while the outer surface is exposed to the elements. During the cooling process, the strip draws heat and/or sweat away from the user, into the cellulose material, and toward the outer surface of the strip, allowing relatively rapid evaporation of sweat and dissipation of heat from the cellulose material as it is cooled from exposure to the elements.

Abstract: A hat with a brim extending outward from the base of a crown wherein a water adsorbent material is disposed on the inside lower portion of the crown, and extends outward onto the underside of the brim. A headband member on the outside lower portion of the base of the crown constricts the crown, causing it to apply the portion of the water adsorbent material disposed therein directly to the head of a user. The crown has venting holes incorporated along the head band. The water absorbent material comprises a closed cell foam material. The closed cell foam material is encased in a water adsorbent matting material to prevent direct contact between the closed cell foam material and the skin of a user.

Abstract: A stretchable sweatband for using a cap comprising a stretchable band, a fabric and a seaming portion is provided. The stretchable band has at least one rubber band and a plurality of elastic yarns, which are sewed together along a longitudinal direction. The fabric covers the stretchable band along the longitudinal direction thereof. The seaming portion is used to seam the fabric and the stretchable band together, which is capable of adjusting the longitudinal direction of the stretchable sweatband.

Abstract: A cap with ventilating holes is provided by the invention. More particularly, the cap is formed with a main body having a curved band shape, which includes a moisture absorbing surface on an inner surface and a Velcro layer or clips on an outer surface of the main body in addition to vertical ventilating holes formed vertically through the main body and horizontal ventilating holes formed horizontally between the vertical ventilating holes and the inner surface of the main body, which facilitates the airflows between inside and outside of the cap.

Abstract: Headwear such as a hat, cap, or visor with a headband and a brim extending outwardly therefrom includes a crescent shaped opening defined by an inner portion of the brim and an external leading edge of the headband. Beyond the opening the opaque brim extends away from the headband to an outward tip, and to lateral side edges. The opaque brim is attached at its lateral edges directly to the external leading edge of the headband. The crescent shaped opening allows more flow at a central area of the brim, yet it narrows toward lateral edges of the brim to ensure that sunlight toward the wearer's sides is adequately blocked from eye contact. This novel structure provides maximum shading of the wearer's face, yet directs considerable airflow from beneath and above the brim through the opening to cool the wearer's eccrine glands along the forehead.

Abstract: The invention is an article of headwear that incorporates an adjustment system for accommodating individuals with various head dimensions. The headwear may be formed of a crown and a visor. With respect to the crown, the adjustment system includes a first elastic material, which forms a majority of the crown, and a second elastic material, which is screenprinted or otherwise attached to a flap positioned within the crown. Regarding the visor, the adjustment system resides in a visor board configuration wherein slits are formed to separate various portions of the visor board. The slits permit the portions to move relative to each other, thereby permitting the visor to expand to accommodate stretching of the crown.

Abstract: A baseball-style cap having a free-size capability for accommodating wearers having a range of head sizes without a separate sizing mechanism. The cap includes a crown main body which is expandable at least in a peripheral direction, and a headband made of a substantially non-stretchable fabric material. The headband is connected to the lower peripheral edge of the crown main body by a piece of stretchable fabric which is sewn to cover the headband. The lower peripheral edge of the headband is incised or grooved at regular intervals such that a stretching force thereon in the peripheral direction causes the headband to demonstrate teeth appearance.

Abstract: A detachable disposable sweatband, that can be readily manufactured from inexpensive readily-available component materials at low cost that makes it practically disposable and thus beneficial to personal hygiene, is easily attached to the sweatband or interior periphery of practically any existing headware. A composite central core of special highly-absorptive material, based on basic principles of feminine hygiene pads, accepts and retains more sweat than comparable sweatbands of prior art and thus provides better protection to the eyes and face of the wearer. The sweatband can be easily detached and discarded, and then replaced at low cost whenever desired, thus eliminating the usual inconvenience and cost of laundering or discarding and replacing the headwear.
