2. The head cover of claim 1 , further comprising at leak one elastic strip.

3. The head cover of claim 1 , wherein the bottom edge has at least a first slope and a second slope, and where the first slope is not equal to the second slope.

4. The head cover of claim 3 , wherein the first slope is a slope of a point between the anterior portion and the posterior portion, and the second slope is a slope of a point adjacent to one of the anterior portion or the posterior portion, and where the absolute value of the first slope is greater than the absolute value of the second slope.

5. The head cover of claim 3 , wherein the bottom edge further comprises a third slope that is not equal to the first slope or the second slope.

6. The head cover of claim 1 , wherein the second height is about 1.1 to about 3.3 times the first height.

7. The head cover of claim 2 , wherein the head cover has a relaxed length when folded along a medial line of from about 18 cm to about 28 cm.

9. A head cover comprising:
an anterior portion having a bottom and a first height;
a posterior portion having a bottom edge and a second height;
at least one side panel having a bottom edge, the bottom edge of the at least one side panel extending between the bottom edge of the posterior portion and the bottom edge of the anterior portion; and
wherein the second height is about 1.1 to about 3.3 times the first height.

10. The head cover of claim 9 , wherein the first height is from about 7 cm to about 17 cm.

11. The head cover of claim 9 , wherein the second height is from about 11 cm to about 23 cm.

17. A head cover comprising:
an anterior portion having a bottom edge and a first height;
a posterior portion having a bottom edge and a second height;
at least one side panel having a bottom edge, the bottom edge of the at least one side panel extending between the bottom edge of the posterior portion and the bottom edge of the anterior portion; and
wherein at least a portion of the head cover comprises a wettable spunbond-meltblown-spunbond material.

18. The head cover of claim 17 , wherein the wettable spunbond-meltblown-spunbond material comprises the wettable spunbond-meltblown-spunbond material treated with an anionic or cationic surfactant.

19. The head cover of claim 17 , wherein at least a portion of the wettable spunbond-melthlown-spunbond material includes a polypropylene and random co-polymer resin.
