Usually worn underneath the hard carapace armour plates of Combat Armour is a set of one-piece overalls constructed of a composite nanocular thread; a microscopic, super-dense mess of fibres that helps prevent projectile punctures and slashing penetrations, whilst remaining flexible. The material the fatigues are constructed from is also chemically threaded to retard flames and the effects of most irritant gases or chemicals. The fatigues are hard-wearing and suitable for most combat environments, and are issued in a variety of colours.
