Ok, so in light of recent events, I've finally decided to start putting together a Bug Out Bag. I've got a list of stuff that I've been acquiring and putting into a surplus miltree backpack.
Now, this is the BOB that I plan to store in my car, which means I'll have to rotate the perishables every 3-6 months. The one thing that really kind of has me stymied is water storage. I've looked at the stuff that comes in the boxes and pouches, but having talked to a couple of people, get the impression that they don't offer any advantage above and beyond bottled water that one can buy in the grocery store.
Since I live in Colorado, I expect temperature fluctuations to cause the water to freeze and thaw several times during the course of the winter. Now, I've done a bit of experimenting by taking a bottle, freezing it and allowing it to thaw several times, and the seal didn't break. However, Murphy tends to pop in for a visit at the worst times, and I'd like to have something that I could enclose these water bottles in that would keep them from leaking all over the other stuff in the bag in the event that one of the bottles ruptured.
Originally I was thinking some sort of ziploc bag, but the standard ones seem to leak. I haven't tested any of the more heavy-duty ones like the freezer bags, though.
Any suggestions?
