how much does a suit of plate armor weigh
Plate armour A complete suit of plate armour made from well-tempered steel would weigh around 15–25 kg.[2] The wearer remained highly agile and could jump, run and otherwise move freely as the weight of the armour was spread evenly throughout the body. The armour was articulated and covered a man's entire body completely from neck to toe. In the 15th and 16th centuries plate armored soldiers were the nucleus of every army. Large bodies of men-at-arms numbering thousands or even more than ten thousand men (approximately 60% to 70% of French armies were men at arms and the percentage was also big in other countries) were fighting on foot wearing full plate next to archers and crossbowmen[citation needed]. This was commonly seen in the Western European armies especially of France and England during the Hundred Years War, the Wars of the Roses or the Italian Wars.[citation needed]
Bulletproof vest In 1976, Richard Davis, founder of Second Chance Body Armor, designed the company's first all-Kevlar vest, the Model Y. The lightweight, able vest industry was launched and a new form of daily protection for the modern police officer was quickly adapted. By the mid-to-late 1980s, an estimated 1/3 to 1/2 of police patrol officers[where?] wore able vests daily.[citation needed] By 2006, more than 2,000 documented police vest "saves" were recorded, validating the success and efficiency of lightweight able body armor as a standard piece of everyday police equipment.[citation needed]
