When a bullet strikes Body Armor, it's caught in a "web" of fibers. These fibers absorb and disperse the impact energy that is transmitted to the vest from the bullet.

Because the fibers work together both in the individual layer and with other layers of material in the vest, a large area of the garment becomes involved in preventing the bullet from penetrating. This also helps in dissipating the forces that can cause non-penetrating injuries (commonly referred to as "blunt trauma") to internal organs.

Methods of Construction
Typically, concealable Body Armor is constructed of multiple layers of ballistic fabric or other ballistic-resistant materials, assembled into the "ballistic panel." The ballistic panel is then inserted into the "carrier," which is constructed of fabrics such as nylon or cotton. The ballistic panel may be permanently sewn into the carrier or may be removable.

Ballistic fabric is available from a number of manufacturers in various styles and compositions, each type having unique ballistic-resistant properties. The location and number of layers of each style within the multiple-layer ballistic panel influence the overall ballistic performance of the panel.
