With the proper materials, armor can be modified to be more protective from physical, energy and radiation damage. Tinker Tom has even made normal clothing a viable form of protection by lining them with a protective undergarment.
- All armor sets can be modified from the get-go using the armor workbench.
- However, in order to be able to modify clothes and outfits with special lining, the player has to join the Railroad and prove his loyalty to Tinker Tom. Doing so will unlock the ability to use ballistic fiber for apparel modifications (specifically the ballistic weave mod).
Please see the relevant armor page for a list of mods available for that armor.
