Pieced together from scraps of armor, this outfit provides protection without impacting mobility. It uses the same model of the raider blastmaster armor from Fallout 3 and from Fallout: New Vegas. It is a single-sleeved suit of armor with a piece of a tractor tire over the shoulder for protection (for males). It can be repaired with other suits of raider armor, including sadist, badlands, and blastmaster armor.
Originally, the only way to acquire this armor was by redeeming the code that came with the pre-order exclusive Tribal Pack. It can now also be acquired by purchasing the add-on Courier's Stash.
The armor lacks the defense of even leather armor (in fact, it has the lowest DT of the armors added by the pre-order bonuses). However, its high durability, the fact that it is free and immediately available, and ease of maintenance make it quite useful early on before better equipment becomes available.
Curiously, the right glove of the armor is not visible on the character of the Tribal Pack advertisement picture.
