Ballistic Weave

The Ballistic weave is an armor mod that allows you to add 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, you can upgrade any applicable clothing item at an Armor workbench.

Guide

 * 1) Find and begin performing Railroad faction quests until P.A.M. gives a quest to secure a DIA cache.
 * 2) After completing this quest for P.A.M., you can 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 to the player at any Armor workbench.
