at least one reinforcement member positioned in proximity of the outer surface of the shock-absorbent layer, the reinforcement member defining an aperture that at least partially aligns with the opening, the aperture having an approximately same size and shape as the opening, the reinforcement member being substantially the same size as the hole.
17. The system of claim 16 , wherein the opening and the aperture are substantially aligned.
18. The system of claim 16 , wherein the reinforcement member is positioned no more than 0.5 inches from the outer surface.
19. The system of claim 16 , wherein the shock-absorbent layer comprises an inner surface, and wherein the reinforcement member is positioned closer to the outer surface than to the inner surface.
20. The system of claim 16 , wherein the shock-absorbent layer is formed from one or more first materials and the reinforcement member is formed from a second material that is tougher than the one or more first materials.
21. The system of claim 16 , wherein at least a portion of the region of the shock-absorbent layer defining the hole is formed from expanded polystyrene and the reinforcement member is formed from a polycarbonate plastic.
22. The system of claim 16 , wherein at least a portion of the region of the shock-absorbent layer defining the hole is formed from expanded polystyrene and the reinforcement member is formed from carbon fiber.
23. The system of claim 16 , wherein the shell defines an opening corresponding to the hole, wherein the reinforcement member is embedded into the shell.
24. The system of claim 16 , wherein the reinforcement member is disposed between the shock-absorbent layer and the shell.
25. The system of claim 16 , wherein the opening and the at least one reinforcement member each comprises a substantially oval shape.
26. The system of claim 16 , wherein:
a first reinforcement member is associated with a first hole and a second reinforcement member is associated with a second hole; and
at least the first and second reinforcement members are joined directly or by an extension to form a cluster.
27. A system for head protection, comprising:
a first means for absorbing shock defining at least one hole;
a second means for absorbing shock overlying the first means; and
