Abstract: A helmet includes a shell having a lower edge, and an edge support extending around the lower edge of the shell. The edge support has a greater structural rigidity than the shell. The helmet can further include a retention strap system, and the edge support can include at least one attachment to attach the retention strap system to the helmet. The attachment can, for example, include a seating, and the helmet can, for example, further include an abutment member removably seatable within the seating. The abutment member can be attachable to a strap of the retention strap system.

Abstract: The present invention provides pads and padding systems for use in protective helmets, and particularly ballistic helmets. Generally, the pad includes a first, outer layer which provides substantial impact resistance and a second, inner layer which provides cushioning and comfort. The pad does not require the use of a moisture-proof, non-perforated, encapsulating layer since both layers provide little resistance to fluid flow. The pad may also include a cover made of moisture-wicking material.
