What makes a Bulletproof vest so bulletproof….?
Kevlar is right but its the tightness of the weave and how it is layered that gives it its strength one layer of kevlar is not bullet proof but 100 more or less is ,it works by spreading out the impact point so you feel it and it hurts but the bullet wont kill you or penetrate the vest ,but depending on the gun you could feel like you got hit with a baseball bat swung by king kong
