Abstract
A composite headband attachable to a face mask and a method for attaching same. The composite headband has at least one discrete elastomeric core and at least one continuous thermoplastic skin layer secured to the elastomeric core. The composite headband has a first modulus in an unactivated state and a second, lower modulus in an activated state. The thermoplastic skin layer forms a microtextured permanently deformed skin layer when the composite headband is in the activated state. In one embodiment, the at least one elastomeric core and the at least one thermoplastic layer are in continuous contact in the activated state. The composite headband is positioned along the headband path and attached to at least one of the left and right headband attachment locations. The headband path is either an axis intersecting the left and right headband attachment locations or a path that generally follows a contour of a surface of the face mask blank.
