A sport face mask is primarily a hollow face mask with a curved surface, made by extrusion wire-shape tubing along a length and width of the face mask, which can be worn on a user's face in association with a helmet or an elliptic pad. At least a part of the wire-shape tubing in the face mask is provided with a cross section in an elliptic or flat shape, and a long side of its cross section is perpendicular to the curved surface formed upon extrusion and assembling into the face mask. According to the aforementioned structure, in using the present invention, compressive and collision strengths of the face mask can be increased, a block to line of sight can be reduced, and a weight of the face mask product can be decreased.
