HUMVEE Driver's Full Tire Tread Armor

I made this armor football pad style; completely from tire tread. I used door hinges to hold the string and to make the shoulder flap pieces flex. Leather belts hold the front to the back. It is not uncomprtable to wear, and very tough. Working with tire tread is very difficult. Tire tread is almost impossible to cut, with the thick rubber and the numerous steel radials. Then once you do cut it, all those radials become sharp needles; not a good thing to have on your skin. But, a sawz-all with the correct kind of blade will cut it, but you may also need a large vice to hold it when you cut.
