Has anyone worn or used Cameleon Invisible Armor?

I found this website that had lightweight armor that could be worn under any jacket or pair of pants.

I'm wondering if anyone has worn or is familiar with this type of gear? From what I can tell, it's lighter weight than a lot of the protective gear, but if it's more comfortable and still works in the way it's suppose to, it might be worthwhile. So I'm just wondering if anyone has tried it.

Thanks for any help you have.
