Bullet proof vests are used extensively by law enforcement officers and the military. A bulletproof vest is a type of body armor. It protects the wearer from physical harm. Body armor has been around for thousands of years. In the beginning the armor was made out of metal and chain mail. It would protect from arrows and swords.

These vests are used mainly by people who are in a line of business that puts them in danger a lot of the time. The effectiveness of the armor will depend on its grade. A lower grade armor will protect from smaller bullets but for higher caliber bullets you will need higher grade armor.
