For anybody that wears soft body armor it has come across their mind at some point in time how exactly does the body armor work and how reliable is it. Technology has changed since the first body armor was produced before WWII. Nowadays, body armor is a proven tool to saving the lives of police officers, military, and anybody else that wears body armor.  It is extremely important to know there is no such thing as bullet proof and there are always circumstances in which a soft armor vests may not provide 100% protection 100% of the time.  However, the statistics strongly favor the use of body armor and studies clearly indicate the lifesaving properties of wearing your armor every day.  This is the number one reason why we strongly encourage any purchaser of body armor to ensure there armor is new and certified to the NIJ standards discussed here.
