But the creme de la creme is ballistic polymer weave. Light weight, serious stopping power, and it looks just like normal clothing.Tinker Tom

The ballistic weave is an armor mod that allows improved defensive stats to certain clothing items, including outfits, clothing that can be worn under armor and a small number of hats.[Fallout 2d20 1]

This crafting ability can be learned from Tinker Tom after performing certain quests for the Railroad faction. Once this skill is learned, one can upgrade any applicable clothing item at an armor workbench.

Obtaining the skill

Progress through the initial Railroad faction quests until P.A.M. offers a series of minor Jackpot missions to secure DIA caches. These only become available after completing Boston After Dark and Mercer Safehouse.

After completing the first or second jackpot mission, Drummer Boy will tell the Sole Survivor that they need to speak to Tinker Tom, who will inform them about the ballistic fiber technology found in the DIA cache. At this point, the ballistic weave is unlocked at any armor workbench and Tom will sell some armored gear of his own.

  • The player character must have the Armorer perk in order to apply this mod beyond the first level. Higher levels of the perk allow applying stronger versions of the mod, up to 110 Damage Resistance and 110 Energy Resistance on a single article of clothing.
  • All levels of this mod require varying amounts of crafting materials.
  • Learning this mod only requires doing one or more Jackpot missions for P.A.M.
  • The ability to make ballistic weave is very useful, if not essential if playing on Survival mode as the damage one receives is mitigated by applying the mod.
  • One wishing to join other factions should be able to safely learn this mod and move on, with the exception of those who have already reached "point of no return" missions with conflicting factions.
  • Many, but not all, companion's base outfits (and some hats) can be upgraded with the weave. If one wants to keep a companion in their original outfit but maintain protection at higher levels, this is one of the best options.
  • The strongest resistance that can be obtained on a single item is achieved by weaving the Mechanist's armor, an Automatron add-on armor set, with 182 Damage Resistance and 182 Energy Resistance. Weaving items that allow other armor slots can bring resistance levels higher than 300.


  • PCPC Due to the dialogue flag setting, it is possible to miss the chance of learning this mod. Drummer Boy will keep saying that Tinker Tom wanted to see the Sole Survivor but Tinker Tom will not initiate the corresponding dialogue. Console command SetStage 5BC93 260 will fix this.[verified]
    • One may also get this mod without doing P.A.M.'s mission with the following console commands:
      Set RailroadClothingArmorModAvailable to 1
      Set RailroadClothingArmor_ChanceNone to 0
  • PCPC Playstation 4Playstation 4 Acquiring the weave may become impossible if one has already finished the game with the Minutemen.[verified]
  • PCPC Playstation 4Playstation 4 The clean black suit is supposed to be moddable, but is currently bugged in-game and prevents the player character from upgrading it on an armor workbench; the only solution for this is to use console commands. Tinker Tom may occasionally sell armored clean black suits, but these will only have the first level of ballistic weave and cannot be upgraded further. [verified]

  1. Fallout: The Roleplaying Game Rulebook p. 126: "Ballistic polymer weave is an armor mod which improves the defensive abilities of some clothing items. A layer of this tough artificial fabric can be used as a lining in a variety of garments, giving them a limited ability to resist impacts, bullets, and energy blasts."
