Abstract
Abstract A liner for helmets, hats, caps or other head coverings has a body with a central section and tapered end sections. The body includes liquid absorbing material and is releasably secured to the head covering for easy replacement. The liners are typically disposable and may be formed with a core of thermoplastic containing other fibers sandwiched between facing and backing sheets. The edges and transversed sections of the body may be densified. Optionally, the liner may be cut in these transverse densified areas to adjust its length.
