The Zygerrian armor was a protective suit that wore some members of Zygerrian castes to protect themselves. It was mostly used by guards and soldiers, who were then ones that were the most likely to need additional protection.
The Zygerrian Armor covered the torso of its user, and included a helmet adapted to their perticular head morphology. The armor was made of a brown, leather like, flexible matter. It offered good protection against blaster bolts, absorbing part of the hits. The armor was able to prevent Obi-Wan Kenobi from being severly injured when he was shot in the back.
