Replace worn-out or damaged reservoirs, or adapt the capacity of your existing GravityWorks four liter system to meet the needs of any trip. The 4.0L Kit includes a 4.0L Dirty Reservoir with Quick Disconnect and a 4.0L Clean Reservoir.
These updated replacement reservoirs feature new clip buckles 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.
