Padded Vest

#Equipment
A thick, sleeveless, quilted cotton corselet (ichcahuipilli). It proved so effective that Spanish conquistadors adopted it themselves, calling it escaupil (see Spanish Conquistador, pp. 13-14).
Layered cloth armor provides better protection than a similar weight of leather armor.
