How effective is body armor?
Body armor helps absorb the impact and reduce or stop penetration of a bullet into the body. When a bullet or projectile strikes the body armor, it is caught in a web of high- performance fibers that are layered and stitched to exceed certain bullet resistant specifications. Additional energy is absorbed by each successive layer of material in the vest, until such time as the bullet has been stopped.
The two most common types of armor are “soft armor” and “hard armor”. While soft armor tends to be fairly lightweight and suitable for everyday wear, hard armor is heavier, so it is reserved largely for tactical vests and any application where the wearer will have it on for a relatively short period of time.
