Sprinkle some water on the outer fabric. If it beads up and rolls off, the DWR is still working. If the water spreads out and soaks into the fabric surface (darkening it), the DWR has worn off and needs reapplication. This is important because a wetted-out outer fabric blocks the membrane from breathing, making the inside feel clammy even though the membrane is still waterproof.
