Raider armor

Raider Armor is a name that refers to various types of armor worn by raiders, usually consisting of rough leather panels held together with wire and string.

Fallout 3
Each variant of Raider Armor in Fallout 3 can be repaired using any of the other Raider Armors.

Raider Blastmaster Armor
This armor bears extreme similarity towards the Predators' armor in the Predator series. Wearing this armor with an Enclave Mask, Power Fist, and the possession of a Stealth Boy would make you the ultimate Predator!

Raider Painspike Armor
If you pay close attention to a melee using enemies health it will go down slightly per hit, implying that the spikes on the armor hurt them when they attack!

Raider Sadist Armor
Two severed hands are on the waist of the armor.

Fallout Tactics
A superior version of this armor is Vandal Armor.

Modifiers: +20% Damage Resistance.

Location: This armor is generally not available to Player Characters, although is supposedly can occasionally be looted from raiders' corpses. Even if you somehow manage to obtain it, it is pretty much useless, as it is even worse than the starting Leather Armor.

Trivia
In the movie Mad Max 3, Max is hired by Auntie Entity (played by Tina Turner) to "take care of" the sub-chief Masterblaster. As an obvious nod, these armors strongly resemble that worn by various "less scrupulous" characters in the Mad Max trilogy.
