    Wanting to get some armor soon.
    I have heard that the Israel stuff is very goo, any truth to that?
    Also I am a big boy 12.5" nip to nip and a 52" chest. I wear a 4x T shirt and a 48" waist. Looking for ceramic. What are these tri curve or whatever was mentioned Up above?
    Any guidance is appreciated.
    Roger

Thus, spalling is most commonly seen with parts of the steel broken off the back of the plate where the heat and energy of the round has weakened the integrity of the steel. This is why ceramic is used as it dissipates heat better than steel and a woven ceramic/kevlar firbrous blend (ESAPIs) has better multiple impact protection than sold steel.
    Great explanation. Thanks!
