Two layers of steel, 10mm empty space between...but tested it only with small arms on the range. .22 /.38 special / .45ACP / 9mm Para / .357 / .50 S&W Revolver and 12/76 pumpgun with slug. Last two calibers are the only which full penetrating the whole armour. The others penetrate only the first layer.
