During the 15th Century, medieval armor was entirely made of plate. The Knights of the Crusade Cuirass Body Armor breast plate has two parts of construction with the lower section overlapping the upper section to offer more flexibility. The Knights of the Crusade Cuirass Body Armor is made of 18 gauge thick steel and contoured around the chest area for maximum deflection. The steel sections double up the armor's impenetrable shell. The center contour diverts an impact away from the body, protecting the armorer. The lower skirt tapers away from the armor. Impacts bounce off with ease. The rounded shape keeps things safe and comfortable. Adjustable leather straps comfortably support the armor from the top, down. A horizontal leather strap adjusts to your size and secures the Cuirass properly.
