I claim the ornamental design for a headwear, as shown and described.
FIG. 1 is a bottom view of a headwear in accordance with the present design.
FIG. 2 is a rear view of the headwear of FIG. 1.
FIG. 3 is a left side view of the headwear of FIG. 1.
FIG. 4 is a right side view of the headwear of FIG. 1.
FIG. 5 is a front view of the headwear of FIG. 1 shown in a wearable configuration and in an example environment.
FIG. 6 is a left side view of the headwear of FIG. 1 in the example environment of FIG. 5; and,
FIG. 7 is a rear view of the headwear of FIG. 1 in the example environment of FIG. 5.
The two rectangle-shaped outlines defined by broken lines along the surface of the headwear in FIG. 2 depict features of the headwear that form no part of the claimed design. The form of a partial human figure outlined by broken lines in the views of FIGS. 5-7 depicts environmental structure to assist in illustrating how the claimed design may appear when in a position of use and forms no part of the claimed design.
