The 5ive Star Gear NATO Style Jerry Cans are a similar to the original version that was developed at the beginning of World War II to carry fuel. Today they are designed to work for not only carrying fuel, but also for carrying water in any camping environment as well as any survival situation. These military-inspired Jerry Cans hold 20 liters (5 1/4 U.S. gal.) of liquid and are just what you need to keep your equipment running.
