Abstract: An improved headgear includes an outer shell and an inner liner providing a head receiving cavity. A headband has a forward portion and lateral portions secured to the inner liner and a pair of rearwardly extending flexible members having interconnecting free end portions that allow the headband to be adjusted to many heads of different length. A fabric lining covers the headband forward and lateral portions and has slot openings through which the headband flexible members extend. An adjustable opening at the top of the fabric lining facilitates headgear vertical adjustment. A pair of side retention straps extend downwardly from the sides of the outer shell. A pair of rear retention straps mount to respective ones of the side retention straps and are adjustably secured to each other. The inner liner has channels that receive the side retention straps and allow them to drape down in close proximity to a wearer's temples and cheeks.
