Plastic LARP armor
Plastic armor is light and cheap. Sounds perfect, and it's easy to find on Ebay, usually in the pickle barrel plastic variety. In NERO it's worth 2 points / location (3 points / location is the max). On the Ebay auctions they say it looks like black leather or blackened steel. However, I'm told that after a few events it gets scratched up and starts looking like crappy plastic.You can try to wear clothes over it, or some LARPers have decorated their plastic armor with leather or suede.
I also received this comment via email: Hi there, HPDE plastic holds up better than steel and looks better longer than any steel armor and I can prove it to you with a simple test. Take a piece ov barrel plastic and a piece of any steel you can get and put them in water for 2 weeks. Once a day take each piece out and take a hammer and pound on them a few times on grass or dirt. See for yourself at the end what looks better and then look me up on ebay under pitbull_armory.
Here are a few pictures of the plastic pickle barrel armor.
