Capacity 845 oz (25 L) The SquadBak™ eliminates the need for awkward and inefficient jerry cans in the field. Whether hanging in the barracks, an armored vehicle or aircraft, the 25L Reservoir solves the problem of refilling CamelBak® systems while deployed. Quickly backfill by connecting drinking tubes via two HydroLink™ connection points. Or use the large diameter hose to refill through reservoir fillports. Once empty, the system lays flat and can be stored easily due to its flexible design.
