How a Martin Shield Backpack Stops a Bullet

The process of Martin Shield bullet-proof backpack is physics based process through 4 distinct steps:

1. When the bullet STRIKES the backpack shield

  • COVERAGE AREA

2. Bullet is CAUGHT  in high tensile strength of Kevlar layers material

  • 4.7 TIMES STEEL
  • STOP PENETRATION

3. Impact of the energy is DISPERSED causing the bullet to deform

  • SLOWS BULLET
  • DESIGNED TO HAPPEN IN TARGET
4. Energy continues to be dispersed into successive layers of material until STOPPED
  • KEVLAR PLATES
