  • Patent number: 6484323
    Abstract: An inexpensive multi-modality utility hat of non/gender-specific design, having advantageous features providing its user with the novel convenience of readily transforming into several different types of hats in one. For example, the brim portion can be quickly and easily detatched from its central cap portion via a zipper, enabling user to wear only either the cap or the brim separately if desired; -and, if the cap portion only is selected to be worn for a time, the brim twist/tripple-folds into a compact member which concealably stows within an integral-pocket portion of the cap. The cap portion includes an adjustable-cord compliance feature enabling one size to fit all, and may be optionally fitted with a broad or a narrow brim of circular, triangular, or squared motif: -and brim-width may be altered at front or sides via a simple gathering provision. Alternately, my light-weight compact hat can be carried fiat within a backpack.
