Headgear having a plurality of projections extending outwardly therefrom is disclosed. The projections have compliant portions located between each end and are manually manipulatable by bending, twisting and curving into various configurations. The projections are thermoplastic tubes having sidewalls formed of frusto-conically shaped annuli joined in an accordion pleated fashion. The annuli have two stable positions relative to each other, either adjacent in contact or angularly displaced. The two stable positions permit the projections to maintain a particular shape until manually rearranged. Complementary couplings on the free end of the projections allow the tube to be joined to form continuous loops.
