Head suspension system and headgear that have an adjustable visor and method of adjusting same

Headgear adapted to protect a wearer having a visor and a flexible circumferential band adapted to be supported by a head of the wearer. A mounting attachment attaches the visor to the flexible circumferential band at each of two side attachment locations with the visor generally positioned in front of a face of the wearer. The mounting attachment has a slide channel associated with the flexible circumferential band and a slide associated with the visor. The slide is able to slide forward and aft in the slide channel with respect to the face of the wearer and is selectively securable in a plurality of forward and aft positions. This allows the visor to be adjusted inwardly and outwardly with respect to the face of the wearer.
