You can't buy it honestly, that's what he was trying to let you know. Nothing made on this site is supposed to be used at safety protection. Pretty much the only way you'll be able to get it is make it yourself :/
You can't buy them anymore (long discontinued) and even if they are, a set will set you back several thousand dollars.
Basically you would buld yourself the armour, and add a very nice, well sealed, easy to clean painted surface, and be sure you used a relatively durable material, like bondo, not just fiberglass.
Okay, I was wondering how I can lock this thread, and how to make a Master Chief costume (a guide would be nice, im a beginner). I wont wear it for paintball, just becasue it will be cool to have. Once again, I am sorry that I made this thread.
