Lifesaver Bottle
Of all the things we can go without, clean water is not one of them. Secure yourself a steady supply of drinking water in even the worst conditions with the Lifesaver Bottle ($380). Using a highly advanced ultra-filtration system, the Lifesaver will remove bacteria, viruses, parasites, fungi and all other microbiological waterborne pathogens without using chemicals like iodine or chlorine, and features Failsafe technology to shut off the bottle's cartridge upon expiration, preventing you from accidentally drinking contaminated water. It's literally a lifesaver.
