TYI flex-armor

"Flex-armor is probably the least popular of the old Sith War designs that are bought up today. The only people who collect them are true military history buffs. They were surprisingly durable bodysuits and many still function, but typically flex-armor suits were modified by the previous owners. I've found a few suits that protect much better than such ancient armor should be able to."

TYI flex-armor was a type of armor produced by Drolan Plasteel and manufactured during the Great Sith War. The armor protected a wearer's head, torso, arms and legs and could be reinforced with the addition of steel wire or mesh. Flex-amor was designed to be more flexible and maneuverable than dura-armor. Modifications to the armor could improve its resistance to physical attacks at the expense of protection from energy weapons. Republic soldiers equipped with flex-armor were not concerned by this as most battles were fought with weapons such as slugthrowers and swords. The popularity of flex-armor waned when energy weapons became commonplace on the battlefield.
