The supreme ease of the AutoFlow Gravity Filter has converted many backcountry travelers to pump-free water filtration. Now, it offers the luxury of effortless water storage and filtration in a more compact, lightweight and streamlined system. Efficient hollow fiber technology filters up to 1.75 liters per minute, and quick and easy tool-free cleanings maintain high flow rates on extended expeditions. The durable film reservoir rolls tight to reduce bulk for discreet packing, and the food-grade lining ensures better tasting water. Available in two sizes: 2-Liter and 4-Liter. The 2-liter system is perfect for backpacking pairs, or choose the 4-liter system for groups and base camps. MSR products are covered by a three year limited warranty against manufacturing defects in materials and worksmanship. Made in the USA.
