GravityWorks 4.0L Water Filter System

The reviews keep coming and one thing is clear, the GravityWorks™ system is changing how people filter water. Delivering four liters of filtered water is just 2.5 minutes with no pumping, there’s simply no easier or faster way to get safe water away from home. Ideal for bigger groups, the system’s eight-liter (four liters in each reservoir) capacity eliminates both the worry and hassle of keeping plenty of water around for anything you need.

The updated hanger system has a new clip buckle on the webbing for easier hanging. There's also less confusion about which bladder holds the dirty water and which holds the clean with larger graphics and a tinted dirty water bladder. And if you ever had a bladder leak or vacuum lock in your pack, this will fix the issue with corner mounted valves.
