Abstract: A cap for accommodating a wearer with long hair. The cap is sized so as to snuggly fit the head of a female wearer, thereby keeping the opening in the rear of the cap at a consistent, predictable height in relation to the head of the wearer. The opening in the rear of the cap is sized and positioned so as to allow the wearer's hair to pass from the point of accumulation on the wearer's head through the opening without passing under the crown of the cap. Consequently, the crown of the cap is not distorted, and the position of the cap is not displaced, by the wearer's hair.
