A highly advanced, virtually impenetrable gluon mesh, first used by Ketsurui Fleet Yards in the Kylie power armor. Particles that make up protons (quarks and gluons) the gluons and quarks are strung together in a long chain using an alteration of Yang-Mills Theory. This permanently binds the quarks together so they may never be pulled apart. The resulting cloth like substance is impervious to penetration, although it does nothing to stop kinetic energy.

Manufacturer: Ketsurui Fleet Yards, Yugumo Corporation
