Housing component used for construction of EXO items.
EXO Rigs joints themselves are prone to environmental fouling from grit or gibs, and may need protection from the elements to keep operating effectively. A traditional way of handling this is with shells, or housings, around rotating parts. Aside from that, specifically-designed undergarments can also be used to enclose the exoskeleton mechanics in a tough fabric separate from the user, which functions as a protective "skin" for the exoskeleton.
HERC is the only known manufacturer of this shells.
