Yes, a good washing should restore it back to its full loft. If you ever want to wash one yourself, there's lots of good instructions on the web. Pretty easy as long as you have a front-loading washer (or top-loading without an agitator), some down soap and the time to run it for a while in the dryer on low/no heat.
