The LifeStraw Flex with Gravity Bag allows you to filter 1 gallon of water at a time by utilizing physics rather than a physical effort (like pumping). Simply fill the durable bag with water from a water source such as a stream, lake or reservoir, hang it somewhere sturdy, and let the filter go to work. The ultra-light system (6.94 oz) filters out bacteria, parasites, microplastics and organic chemical matter (like pesticides) at a flow rate of 0.5 L / minute with virtually no effort. Fill water bottles or drink directly from the straw while you're camping, traveling, or during emergencies.
