The 1-liter Kangaroo collapsible canteen from Source Tactical is a modular hydration system that works where back-mounted systems often do not. This package includes the 1-liter Kangaroo reservoir and a heavy duty pouch equipped with a MOLLE attachment system that allows for easy mounting onto a vest or rucksack. Source's Glass-Like Film is smoother than standard TPU films with virtually no difference from glass itself, preventing bio-film build up and making the system virtually self-cleaning. Grunge Guard Technology inhibits bacteria growth on the reservoir and drinking tube surfaces for the life of the system. The user-friendly Widepac slide closure (with airtight seal) provides an extra-wide opening for easy filling, cleaning, draining, and ice insertion, and it includes a handle for easy carrying. All Source hydration systems are BPA and phthalate free. It comes with the high-flow Storm valve, a push-pull system that's like drinking from a straw. It also comes with a Dirt-Shield protective cover that protects the valve from valve from dirt, sand, dust, mud, and other pollution. Source has been a groundbreaker in hydration system technology and is also well known for its tactical gear and hiking sandals. Tested in the most extreme conditions, hundreds of thousands of Source hydration systems are in use in the field.
