Recon Armour is constructed in two layers. The outer face is a hard, ultra-dense nano-crystalline metal veneer bonded to an inner layer of high performance, thermo-set, molecular polyethene. The outer layer material is known as Fio'tak in the Tau Lexicon, and is commonly used as a form of armour across nearly all Tau units due to its lightweight nature and impact-resistant structure. The inner layer of Recon Armour acts as an energy-absorbent padding for energy dispersal, and helps prevent blunt trauma effects from high-velocity impacts. The highly advanced materials used in Recon Armour's construction are very resilient to penetration and lightweight compared to more conventional Imperial materials such as plasteel. Additionally, the nanocular-thread fatigues worn beneath Recon Armour by
