Shinobi Battle Armour

During the era before the hidden villages, ninja wore armour that was similar to that of samurai. It boasted a higher defence than the simple stealth clothing that the shinobi would wear on missions that weren't for battle due to being made of plate armour. Shinobi in Konoha continued to wear the armour until at least the First Shinobi World War, when in the second the transition into Flak Jackets began.

The Akimichi clan of Konoha seems to have persisted in the use of armour, sometimes even combining it with the current flak jackets.
