10. The apparatus of claim 1 , wherein the two flat sides comprises a first flat side and a second flat side, the first flat side extending from the flat front to a terminal end, wherein prior to deformation to the U-shape, the terminal end is coplanar with the flat front while the first flat side has an upper edge and a single continuous curved convex lower edge extending from the flat front to the terminal end.

11. The apparatus of claim 1 , wherein the flat front has a width of at least 2 inches.

12. An apparatus comprising:

a protective headwear liner comprising:

an encasement; and

a moldable and hardenable material within the encasement, wherein the encasement is deformable to a U-shape while containing the material prior to hardening of the material, the U-shape having a flat front and two flat sides corresponding to a front and sides of a person's head, respectively, wherein the two flat sides are joined to the flat front by curves and wherein the material is configured to retain the U-shape following hardening of the material,

wherein the encasement comprises:

a lower edge;

a center front portion having a first height above the lower edge;

a first wing portion extending from a first side of the center front portion, the first wing portion having a second height above the lower edge and greater than the first height;

a second wing portion extending from a second side of the center front portion, the second wing portion having the second height above the lower edge; and

a hanging portion projecting below the lower edge from the first wing portion, the hanging portion containing the moldable and hardenable material.

13. The apparatus of claim 12 , wherein the hanging portion is planar and is configured to extend over a temporal lobe of a person wearing the protective headwear liner.

14. The apparatus of claim 12 , wherein the hanging portion is deformable to a U-shape prior to hardening of the material, wherein the material is configured to retain the hanging portion in the U-shape following hardening of the material.

15. The apparatus of claim 14 , wherein the U-shape of the hanging portion has an outermost face including indicia.

16. The apparatus of claim 12 , wherein the encasement is deformable to the U-shape such that the center front portion vertically extends upwardly from the lower edge without bending about a horizontal axis.

17. The apparatus of claim 12 , wherein the first wing portion comprises an upper edge opposite the lower edge and wherein the upper edge has a convex curvature extending from the center front portion to a rearward most terminus of the first wing portion.

18. An apparatus comprising:

a protective headwear liner for a cap having a lower edge, the liner having a lower liner edge and comprising:

an encasement; and

a moldable and hardenable material within the encasement, wherein the encasement is deformable to a U-shape while containing the material prior to hardening of the material, the U-shape having a flat front and two flat sides corresponding to a front and sides of a person's head, respectively, wherein the two flat sides are joined to the flat front by curves and wherein the material is configured to retain the U-shape following hardening of the material, wherein the encasement comprises:

a lower edge;

a center front portion having an upper edge having a first maximum height above the lower edge;

a first wing portion extending from a first side of the center front portion to a first terminal end, wherein a midpoint of the first wing between and equidistantly spaced from the first terminal end and the center front portion has a second maximum height above the lower edge that is greater than the first maximum height; and

a second wing portion extending from a second side of the center front portion to a second terminal end, wherein a midpoint of the second wing equidistantly between and spaced from the second terminal end and the center front portion has a third maximum height above the lower edge that is greater than the first maximum height and wherein the upper edge of the center front portion is concave and extends across a midpoint of the encasement equidistantly between and spaced from the first terminal end and the second terminal end.
