I had some Datrex lifeboat rations in the trunk of my car, and wanted to replace them. Found out, they are heat and cold resistant, and with a 5 year shelf life, mine had two years to go! I replaced them anyways, but one package has 18 bars, about 2 days of chow for two people, following the instructions printed on the package, in a small shrink wrapped blue package. I keep two of them in the Bugout Belt in one pouch, easy fit. No pics right now, but quite frankly, with as easy as these would be to stash, a couple in the trunk/behind the pickup seat might be a lifesaver someday. They are also designed to be low water use, no need to "wash them down". Haven't tried one yet, so I am repeating the company line, but now I have extras, I might have to pop one open and see!
Do not use if allergic to coconuts.
Just another option in a world going nuts.
