• Use of the insert enables the sweat, oils, and odors to get locked in the insert and, therefore, reduces scents odors from accumulating in the head covering.
• Skin hygiene is another important benefit from using the insert 10 or band 50.
• Many adult and teenage athletes who wear helmets or sweatbands during their sporting activities experience increased skin irritation and facial acne during participation while in season. Construction workers may be subject to skin irritation throughout every season, especially the hot, summer months.

• one embodiment of the band 50 illustrated in FIG 39, is comprised of five layers: a top, moisture wicking layer 35; an absorbent core layer 37 comprised of a top absorbent core layer 37a, a super absorbent core layer 37b, and a bottom absorbent core layer 37c; and a second, moisture wicking layer 35.
• one embodiment of the band 50 is comprised of seven layers: a top, moisture wicking layer 35; a first elastic layer 43; an absorbent core layer 37 comprised of a top absorbent core layer 37a, a super absorbent core layer 37b, and a bottom absorbent core layer 37c; a second elastic layer 43; and a second, moisture wicking layer 35.
• a top, moisture wicking layer 35 is comprised of seven layers: a top, moisture wicking layer 35; a first elastic layer 43; an absorbent core layer 37 comprised of a top absorbent core layer 37a, a super absorbent core layer 37b, and a bottom absorbent core layer 37c; a second elastic layer 43; and a second, moisture wicking layer 35.
• a top, moisture wicking layer 35 is comprised of seven layers: a top, moisture wicking layer 35; an elastic layer 43; an absorbent core layer 37 comprised of a top absorbent core layer 37a, a super absorbent core layer 37b, and a bottom absorbent core layer 37c; a impermeable gutter layer 45; and a second, moisture wicking layer 35.
• the moisture wicking layer 35, the liquid impervious layer 40, or both can incorporate flame-resistant fibers (e.g., Nomex by DuPont).
• the device for absorbing and retaining sweat can include an absorption indicator or a saturation indicator, such as a color change indicator, wherein the color changes as more sweat is absorbed, and the change in color enables the user to know how much sweat the device has absorbed and about how much more it can absorb.
• the absorption or saturation indicator can be a strip on the device.
• the device can include glow in the dark materials so that the device is visible in darkness.
• the removable release liner layer 39 is removed from the adhesive layer 41 by peeling it from the adhesive layer 41.
• the insert 10 is then applied to the headwear 20, either by applying it directly to interior surfaces of the headwear shell itself, or to a suspension headband shaped to conform to a user's head.
• the repositionable pressure sensitive adhesive of the adhesive layer 41 holds the insert 10 in place.
• the gaps 30 in the insert 10 facilitate bending of the insert 10 to conform to the shape of the headwear 20, as illustrated in FIGS. 5-12, and to prevent overlapping of the material of the insert 10. By preventing such overlap, a smooth surface of insert 10 lies against the user's head for increased comfort.
• the insert 10 can be firmly secured to the headwear 20 by the repositionable pressure sensitive adhesive 41, with the exposed surface of the insert 10 forming a contacting surface for the wearer of the headwear 20. After use, the insert 10 is easily removed by breaking the adhesive seal between the insert 10 and the curved inside surface of the headwear 20.
• the insert 10 may be an absorbent cylinder that can be elastic.
• the cylinder can include three layers: a top layer, an airlaid layer, and a SAP layer.
• the SAP layer can be in the middle of the cylinder and the layers can be rolled up like a tube.
• several cylinders or tubes can be intertwined or braided together to make a larger end product.
• an insert 10 may contain one or more vents or cutouts that are used for ventilation and circulation.
• the vents or cutouts may be any shape, such as, but not limited to, a linear slit, a rectangle, a non-linear shape, an oval, etc. Further, the edges of the vents or cutouts may each have a sealed perimeter, similar to that described above.
