Armor made of cotton

Centuries ago, the Inca developed ingenuous suits of armor that could flex with the blows of sharp spears and maces,protecting warriors from even the fiercest physical attacks.These hardy structures were made not from iron or steel,but rather something unexpectedly soft: cotton.These thickly woven, layered quilts of cotton could distribute the energy from a blow across a large surface area,shielding warriors without restricting their mobility.
