Abstract: A helmet including a shell and a support system is provided. The shell includes an outer surface and an inner surface. The support system includes a base and a plurality of hollow cells extending outward from the base. The support system substantially conforms to the shell inner surface. The cells are segmented into a plurality of regions wherein the cells within each of the regions are coupled together in flow communication via a plurality of channels extending therebetween. At least one cell within a first region is coupled in flow communication to at least one cell within a second region to enable fluid to be selectively transferred from at least some of the cells in the first region to at least some of the cells in the second region to facilitate reducing an amount of energy induced to a wearer of the helmet following an impact to the shell.
