A flexible bill includes a plurality of flexible line segments disposed inside the bill to keep a fashioned curve according to the line segments influenced by an outer force. The bill 1 is combined to a crown 2 to form a cap by stitching a rear fringe of the bill to a front fringe of the crown 2 . Said bill 1 includes a lining 13 made of ethylene vinyl acetate (EVA) clothed by twill 11 . At least, three flexible line segments 12 are disposed between the EVA lining 13 and the twill 11 . Flexible line segments are arrayed side to side in parallel to the bill equidistantly. They can be disposed above or below the bill 1 . The flexible line segments 12 are made of high density polyethylene (HDPE).
