Lifesaver Jerrycan
Whether you're preparing for the worst or just planning for an extra-long hiking trip, the Lifesaver Jerrycan ($450) is a handy thing to have around. Capable of holding five gallons of fluid, the Jerrycan incorporates the same filtration technology seen in the Lifesaver Bottle, allowing you to transform filthy, germ-ridden water into clean H2O with just a few pumps. And just in case the worst happens, it can filter enough water to sustain a family of 4 for nearly a year — which is way longer than that stash of bottled water in the basement is going to last.
