A dome-like liner that will fit inside of a safety hat is formed from a plurality of stacks of stiff but deformable tubes, the tubes in each stack being arranged in superimposed rows with the tubes in each row parallel and staggered relative to the tubes in the immediately adjoining rows. Each of the stacks is enclosed in a flexible sheath, the sheathed stacks being assembled to form the liner.
