A liner adapted to be interposed between the interior surface of a protective headgear and a wearer's head includes a plurality of networked fluid cells adapted to distribute and dissipate an impact force to the liner, and/or headgear with which the liner is used, across a larger area of the wearer's head as compared with the impact location, and also to dampen the tendency of the wearer's head from rebounding back from the impact location by transferring fluid through the network from fluid cells at the impact location to those in an opposed region. Discrete fluid cells interspersed among the networked fluid cells maintain the liner and/or the headgear in a predetermined orientation on the wearer's head. Fluid flow within the liner may be restricted or directed by configuring the fluid passageways. A liner may further include means for moving fluid into or out of the fluid cells.
