Abstract: A head cap having an opening on its upper central or crown portion of the cap body, the opening being for receiving a "ponytail" hair style, with the walls around the opening providing lateral support to the ponytail. A neat and trim appearance of the ponytail extending through the opening is achieved, and the attractive vertical support is given to the ponytail even though given only by lateral support. In another embodiment, at least two openings are provided, spaced laterally of the median line of the cap body, accommodating a dual ponytail style.
