The “Lifestraw” would have to be the most important piece of kit in a survival situation. It filters water from bacteria that causes diarrhoea type infections. It needs no power source, no batteries, lasts a year from it’s first use and can filter up to 1000 litres of water. For $30 it’s available to us here in Australia through Survival Store House: http://www.survivalstorehouse.com
