What is claimed is: 1. A helmet comprising: a shell defining a cavity configured to receive a user's head, the shell including an exterior shell surface and a receiving area recessed into the exterior shell surface; a liner within the cavity and coupled to the shell; a facemask coupled to the shell; and a front bumper coupled to the shell and positioned at least partially within the receiving area of the shell. 2. The helmet of claim 1 , wherein the shell includes a first ridge and a second ridge extending away from a rear surface of the shell, wherein a rearmost point of the first ridge and a rearmost point the second ridge lie within a reference plane that is rearwardly spaced from the rear surface of the shell when the helmet is resting on a horizontal surface. 3. The helmet of claim 2 , wherein each end of the first ridge is curved upwardly toward a top of the shell and each end of the second ridge is curved downward toward a bottom of the shell. 4. The helmet of claim 2 , wherein the shell includes a first opening proximate each end of the first ridge and a second opening proximate each end of the second ridge. 5. The helmet of claim 4 , wherein the first openings and the second openings are arranged to form a generally X-shaped pattern. 6. The helmet of claim 1 , wherein the front bumper is coupled to the shell and the liner and the front bumper extends from within the cavity to an exterior of the shell. 7. The helmet of claim 1 , wherein the front bumper is positioned within the receiving area such that an outer surface of the front bumper is generally flush with the exterior shell surface. 8. The helmet of claim 1 , wherein the front bumper is positioned within the receiving area such that an outer surface of the front bumper is recessed toward a center of the shell relative to the exterior shell surface. 9. The helmet of claim 1 , wherein the front bumper includes a recess configured to receive at least a portion of the facemask. 10. The helmet of claim 1 , wherein the front bumper is positioned within the receiving area such that a top edge of an outer surface of the front bumper is flush with a top edge of the receiving area. 11. The helmet of claim 1 , wherein the front bumper abuts an edge of the receiving area. 12. The helmet of claim 1 , wherein the front bumper is spaced from an edge of the receiving area. 13. The helmet of claim 1 , wherein the front bumper is detachably coupled to each of the shell and the liner. 14. The helmet of claim 1 , wherein the exterior shell surface includes a first side portion, a second side portion and a central portion extending between the first side portion and the second side portion, wherein the exterior shell surface going from the first side portion to the central portion is recessed and the exterior shell surface going from the second side portion to the central portion is recessed, wherein an apex of the central portion is the top most element of the shell when the helmet is resting on a horizontal surface. 15. The helmet of claim 1 , wherein the exterior shell surface includes a rear portion, a front portion, a first side portion, a second side portion and a central portion extending from the front portion to the rear portion and between the first side portion and the second side portion, wherein a perimeter of the central portion is recessed relative to the first side portion and the second side portion proximate the front portion and protrudes relative to the first side portion and the second side portion proximate the rear portion. 16. The helmet of claim 1 , wherein each side portion of the shell includes a recessed area, the helmet further comprising: a chin protector coupled to the recessed area of the shell by a chin protector fastener. 17. The helmet of claim 1 , wherein the liner is detachably coupled to each of the shell and the front bumper such that the liner can be detached from the shell and the front bumper while the front bumper remains coupled to the shell. 18. The helmet of claim 1 , wherein the liner is detachably coupled to the shell. 19. The helmet of claim 1 , wherein the shell is comprised of nylon.
