Bullet-resistant materials (also called ballistic materials or, equivalently, anti-ballistic materials) are usually rigid, but may be supple. In some instances, the bullet will stop in its tracks, frozen by the plastic and sealed inside. It's important to keep the weave dense enough to reduce projectile penetration, and the more layers can remain intact, the more they will help redistribute (spread out) the force of the impact, reducing blunt-force trauma. 44 Magnum and .
