Ballistic Weave

The ballistic weave is an armor mod that allows adding defensive stats to most clothing items, including outfits, clothing that can be worn under armor, and a small number of hats. 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.

Find and begin performing Railroad faction quests until P.A.M. gives a series of minor quests (Radiant?) to secure DIA caches (these become available after doing Boston After Dark and Mercer Safehouse). The missions can include, but may not be limited to:


 * Jackpot: Hub 360
 * Jackpot: Medford Memorial Hospital
 * Jackpot: Ruined Skyscraper

After completing several of these quests for P.A.M., Drummer Boy will tell the Sole Survivor they need to speak to Tinker Tom, who will talk about the DIA cache, mentioning ballistic fiber upgrades and offering some armored gear. At this point the armor mod is unlocked at any armor workbench.
