2. Description of Related Arts

Caps are known in art and become necessities to people during outdoor activities. Conventionally, a cap comprising a cap body having a cap cavity and a cap peak outwardly extended from a bottom brim of the cap body in such a manner that when the cap body is put on a wearer's head, the cap peak is capable of blocking the sunlight directly towards the wearer's eyes so as to provide a shading purpose. Therefore, many sportsmen would like to wear a cap during the outdoor activities.

For example, baseball players would like to wear a baseball cap for shading because they have to catch the baseball flying in the sky. However, when they run from one direction to another direction, the sunlight may directly shines on their faces. Therefore, they have to turn the cap around their head for shading the sunlight. Sometime, it is a hassle for them to switch the cap peak to block the sunlight so that they may throw the cap away to prevent missing of the catch of the ball.

Moreover, the cap body is constructed by a plurality of fabric made cap leaves connected with each other edges to edges. Since different wearers have different head shapes, the cap cavity of the cap body is capable of deforming its shape to fit the head shape of the wearer after a period of time. Therefore, when the wearer needs to turn the cap around his or her head at the time, the shape of the cap body will be distorted.

In addition, it is a hassle for the wearer that he or her must initially take off the cap from his or her head and put it back on in order to turn the cap around the head. For example, a quick adjustment of the cap peak is required for the wearer during driving. However, the procedure of turning the cap around will disturb the wearer who is driving.
