Abstract: A headwear piece having a body with an opening to accept the head of a wearer. The body has an exposed external surface. An element defines at least a part of the exposed external surface of the body. Frangible structure connects the element to the body so that the frangible structure can be ruptured to at least partially separate the element from the body.

Abstract: A headwear piece having a crown defining a receptacle for the head of a wearer and illumination structure on the crown for projecting an unfocused light as an adornment to the crown to be visible from externally of the crown.

Abstract: A headwear piece having a crown defining an opening for reception of the head of a wearer, structure for varying the effective diameter of the crown opening to accommodate different size wearer heads, and an actuator for operating the crown opening varying structure. The actuator includes a switch which, in one form, is a dial that is rotatable about an axis to operate the crown opening varying structure to thereby effect the variation in the effective diameter of the opening in the crown. In another form, the switch is translatable to effect a variation in the diameter of the crown opening.

Abstract: A headwear piece having a crown defining a first opening for reception of the head of a wearer, an inflatable bladder mounted to the crown so that the bladder resides between the crown and a wearer's head in the crown opening, structure for selectively introducing a fluid into the bladder, and structure mounted to the crown for covering the fluid introducing structure and allowing operation thereof from a location externally of the crown.

Abstract: A headwear piece with a crown for placement on the head of a wearer and having a front and rear and a top and bottom. The crown grips the head of the wearer to maintain the headwear piece in place. The crown has a front wall with a forwardly facing surface. The front wall blends into a top wall that extends rearwardly and terminates at an edge that bounds an opening in the crown through which a substantial portion of a wearer's head can be exposed with the headwear piece in place on a wearer's head. The top wall edge extends from the front of the crown no more than two-thirds, and more preferably no more than one-half, the distance between the front and the rear of the crown.

Abstract: A headwear piece having a crown defining an opening to accept the head of a wearer, with the crown having a top and bottom, front and back, and a peripheral wall having an annular configuration. An opening is provided through the peripheral crown wall to allow passage therethrough of an accumulation of hair on the head of a wearer with the headwear piece in place on the wearer's head.

Abstract: A headwear piece having a crown with a surface defining an opening for receiving the head of a wearer, a bladder having first and second layers defining a space therebetween for containing a displaceable fluid, structure for connecting the first and second layers to each other to divide the bladder space into first and second chambers with their being a communication path through the bladder space between the first and second chambers, and structure for connecting the bladder to the crown so that the bladder defines a deformable cushion layer to conform to the head of a wearer.

Abstract: A headwear article having an inverted cup-shaped crown for placement over the head of an individual, a band on the crown with a surface embracing the head of the individual wearing the headwear and an inflatable element on at least one of the crown and band for varying the effective diameter of the band surface.
