Just got these back in after not seeing any for about 6 years! These Swiss Army water storage bags are great. They hold 20 liters (5 gallons)of potable water. Marked "For drinking water only" in German, French and Italian. Made from very heavy duty rubber, I can stand on one of these when it is full and it holds me up. Has rugged rope/plastic handles on each end, a combination cap/push button spigot that unscrews to fill, then when you hang the bag by its handle you can easily dispense water. Lays nice and flat for storage when empty, and the design means you can look at them and instantly see how much water remains.
