I was recently in the market for a cycling hydration pack. While browsing Camelbak's website I noticed they had a military/tactical category; not my style but that's not the point. When I clicked in there to see what type of stuff they had to offer, I noticed that they had hydration reservoirs that are designed to be impervious to chemical and biological weapons. Pretty cool technology I'd say. Then I noticed that I couldn't even order such a reservoir if I wanted to, because the website says: http://shop.camelbak.com/cbr-x-reservoir/d/1210_cl_3153 Does anyone ever wonder why things such as this are not available to civilians? And of course I'm not singling out Camelbak, I'm sure there are plenty of other items out there that aren't available to civilians either. Does the government have a reason for not wanting people to have this sort of technology available to it's citizens who may be interested in prepping for a disaster? I'd be interested in hearing people's thoughts.
