Fact You Might Not Have Known About #bulletproofvest

Body armor is comprised of very strong non-woven and/or woven fibers. The material will stop a bullet similar to how a net will stop a tennis ball or volleyball. It causes the bullet to turn, slow it down and send its energy through the whole panel. The bullet mushrooms, which helps in the process. Keep in mind that the heavier and slower the bullet is, the better off the wearer is going to be. Bullets that have a hard tip or fired at a high velocity will get through the fibers and right through the bullet proof vest.
