The present invention provides an adjustable, flexible headgear band (10). T he band (10) comprises a first end (20) and a second end (30) which overlap. The first end (20) comprises a plurality of longitudinal ly spaced slots (40) therein. The second end (30) comprises a resilient fastener (50) formed integrally with the second end (30). The resilient fastener (50) comprises a channel (54) to slidably receive the first end (20) in overlapping engagement with the second end (30). The fastener (50) comprises a fastener surface (56) from which at least one flange (52) extends to engage and be seated in one of the pluralit y of slots (40) of the first end (20). The fastener surface (56) is resiliently bowable in a direction away from the first end (20) upon application of compressive force to the fastener (50). Upon application of such compressive force, the at least one flange (52) is unseated from the slot (40) in which it is seated so that the first end (20) can be slid relative to the fastener (50) (and thereby the second end (30)). The second end (30) further comprises at least one latitudinally extending notch (70) adjacent the fastener to facilitate bowing of the fastener surfac e (56). Preferably, two such notches (70, 72) are provided, one extending from the top of the second end toward the center thereof, and one extending from the bottom of the second end toward the center thereof.
