Abstract: A form-maintaining insert for a cap which underlies the crown of a cap in face-to-face relation and provides tension in order to resist wrinkling or creasing of the crown so that the rear wall of the cap may be folded inwardly thereby reducing the space occupied by the cap.

Abstract: A first wall and a second wall coact with a portion of a head covering section of a head covering to define an inner pocket and an outer pocket. The first wall is taller than the second wall to define a flap-forming portion; and a fold in that first wall permits that flap-forming portion to be moved outwardly over and downwardly below the level of the upper edge of the second wall to block the entrance to the outer pocket. That fold has a curved configuration in plan view so it tends to hold the flap-forming portion adjacent the outer face of the second wall as long as that fold exists. When the flap-forming portion is moved upwardly away from the outer face of the second wall to a position wherein it is generally in register with the lower portion of the first wall, a curved configuration of that lower portion of the first wall will resist movement of that flap-forming portion outwardly over and downwardly below the level of the upper edge of the second wall.
