Tactical Info[]

  • Confers 2 armor HP


  • On the lower game difficulties and for Rookies, the option to equip a Nano-Fiber Vest should be weighed against the tactical benefits of a grenade: clearing cover, killing multiple aliens and making new room entry points.
  • On the higher game difficulties, the Nano-Fiber Vest is a critical stop-gap armor necessary to increase soldiers' survivability until Carapace Armor is unlocked.
  • Once available, Chitin Plating provides superior bonuses to the Nano-Fiber Vest.
    • In XCOM: Enemy Within, the Respirator Implant offers the same health bonus but also provides protection against poison and strangulation.
    • Researching Tactical Rigging early allows the Nano-Fiber Vest to be equipped alongside another item, greatly increasing its utility.
