Abstract: The hat crown has a lower periphery, an outside and inside, a horizontal brim and a headband placed radially inward from the crown's interior. A sliding assembly has one member fixed to the crown's inside and a second slidably attached to the first as a extension to the brim. The brim may then be rotated along the crown. The crown's material includes a fold folded inward to form a finished edge along the lower periphery. The fold, securely attached to the main portion, forms an upper edge. The first member has a flat base fixed to the fold or arranged at the flap's top and connected directly to the crown in any suitable way. If the crown is seamed, the headband can be tacked on or near the seam lines. The headband may also surround the lower periphery incompletely so as to create a gap with two edges, an elastic band separating them and stretching to adapt to the wearer's head.

Abstract: There is provided a hat comprising a crown portion, a brim removably and rotatably attached to the crown portion by a sliding assembly, a circumferential band attached along its lower edge to the lower periphery of the crown portion and having at least a first part of the sliding assembly attached thereto, a headband attached to the circumferential band and/or the crown portion, but preferably not to the sliding assembly, that is disposed between the sliding assembly and a wearer's head when the hat is worn. The sliding assembly comprises a first member at least partially secured to the inside of the crown portion and/or the circumferential band, and a second member at least partially secured to the brim. The sliding assembly is preferably vertically oriented so that, in particular, the sliding assembly may be recessed from the lower periphery of the crown portion for improved functioning and aesthetics.
