Soft Body Armor is a misnomer for a category of Body Armor which is quite efficient at protection from various bullets. No doubt it is not 100% save but provides a reasonably good protection and that to at a much lighter weight than that of its counter part the Hard Body Armor. Soft Body Armor are made our of multiple layers of specially woven fabric which have special qualities. The use of this special fabric in multiple layers gives it the ability to absorb the impact of the incoming bullets with ease and helps in spread of the force of the impact of the bullet thereby preventing it from piercing through the armor. An analogy can be drawn to the soccer goal. When the net receives an impact of the ball, it stretches and moves back slightly and in the process absorbing all the energy the ball has. The whole net is made in such a way that it will absorb all the energy of the moving ball and brings it to rest and does not deflect it. This is principle on which the Soft Body Armor work. The layers of the fabric woven in a special manner using high strength synthetic fibers move in tandem all the while absorbing all the bullets energy and bringing it to halt thereby allowing for least damage and injury to the wearer of the armor.

If you see a piece of bulletproof fabric under a powerful magnifier, you would be able see a similar structure. The fabric uses long strands of special fiber which are interlaced in a particular manner to form a very dense net. Usually a bullet is travels much faster than any soccer ball, so the net required for absorbing the impact needs to be made from super strong material. These Soft Body Armors are now reinforced with special light weight plates to provide protection from extra strong rifle and gunshots.
