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 Badlands Armor
A bandolier is draped across the front of the apparently leather overshirt (vaguely resembling a tank top), and on the left knee there appears to be some sort of collinder being used as a knee pad. The outfit also includes shorts made from either leather or some variety of canvas-like material, in contrast to the legwear of virtually every other outfit in the game, which feature only trousers. A screwdriver is secured near one boot, presumably to be used as a makeshift boot knife, despite the fact its only function is for aesthetic value. It's also feasible that it is the screwdriver used by the player when picking a lock.

Raider Blastmaster Armor
This armor bears a similarity towards the Predators armor in the Predator film series.

Raider Painspike Armor
If you pay close attention to an opponent using melee or unarmed attacks, its health will go down slightly with every hit, implying that the spikes on the armor hurt them when they attack, even though the spikes are not in a suitable position to damage an attacker.

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

Cut versions
The three cut versions of Raider Armor in the game files have a lower DR than regular Raider Armor (by one point) and can only be obtained through the console.

Hand-Me-Down Raider Armor
The Hand-Me-Down Raider Armor is visually identical with Raider Sadist Armor.

Highway Scar Armor
The Highway Scar Armor is visually identical with Raider Blastmaster Armor.

Sharp-Dressed Raider's Armor
Sharp-Dressed Raider's Armor is visually identical with Raider Painspike 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.
