I claim the ornamental design for a twist knitted ponytail hat, as shown and described.
FIG. 1 is a perspective view of a twist knitted ponytail hat, showing my new design;
FIG. 2 is a front elevational view thereof, the rear elevational view being a mirror image thereto;
FIG. 3 is a top plan view thereof; and,
FIG. 4 is a bottom plan view thereof.
The broken lines in FIG. 1 showing a person with a ponytail depict environmental structure to assist in illustrating how the twist knitted ponytail hat may appear when worn and forms no part of the claimed design. The broken line in FIG. 4 that encircles the interior of the twist knitted ponytail hat and the adjacent unshaded surface area depicts portions of the twist knitted ponytail hat that form no part of the claimed design.
