Disclosed is a flexible, odor-absorbing web for use under casts or other devices used in prolonged close contact with the human body. The web comprises a sheet-like matrix comprising an open-celled or closed-celled foam, or cellulosic fibers in a binder, filled with activated carbon particles. On the surface of the matrix designed for contact with the skin is a hydrophobic fiber layer, preferably needle-punched into the carbon-containing matrix. The opposite surface of the matrix may include a hydrophilic fiber layer.
