An adjustable paper cap is provided as an article of protective headgear particularly adapted for use in food serving and processing facilities as well as in various other types of factories or manufacturing facilities. The cap includes two elongated side panels, one of which has two sections that are telescopically adjustable in a longitudinal direction for accommodating size adjustment. A crown fabricated from a relatively thin and flexible sheet material formed with a multiplicity of pleats to permit substantial lateral expansion and is secured between the side panels. Each side panel is formed with relatively narrow, single-folded, longitudinally extending, upper and lower marginal edge portions which enable the two sections of the one panel to telescopically interfit in securely retained relationship. The crown is attached to the side panels through adhesive bonding of a downwardly directed, outermost panel of the pleated crown to the upwardly directed, bottom marginal edge portion of the respective side panel. The attachment is such that an extremely comfortable, yet snug fit is achieved. Only a folded over, vertical end portion of the crown is secured to the side panel section to minimize interference in telescoping of the two sections while maintaining the unattached portions of the crown in close association with the adjacent panel surface.
