Blissmommy,
Here is my BoB list. Sorry, that it took me to get back to you. I had to some new links for you, since the old ones didn't work. Hope this helps, if you need some links, let me know, also, If your like my wife, she waits for sales, Ebays, or finds sites that warn when things go on sale. Of course, dollar general it or shop around...While Amazon is quick, its not always the cheapest. I think I have over 500 sites, but I am pretty selective on quality versus real deal.
Example: You will find people buying those lovely little Czech Gas Masks...what a deal, but if you've never taken a mask cartridge out like those found in that crap, you will know that it takes about 5 minutes to change a filter and that is if that's not when your not under stress or holding your breathe. Here's my take, spend the money on a new mask, a good one that will take a 3M CBRNE cartridge will cost about between 130 to 220, also you can find all the cartridges are new with good shelf life...would you depend your life on a 30 dollar mask, my take, I think my family knows. Please note: Keep the masks outside of your BOB, "D" link it to your LBE gear or to the outside of the mask. Don't leave the mask under California summer heat and don't expose the cartridge to moisture. The CBRNE can's are like SPAM can's, easy to open either using the SPAM can key attached to the outside of the container or you can use a canopener or P-38, which is in your BOB, I also keep one on my dog tags. I buy from these guys because they supply law enforcement and have great shelf life on their cartridges.
