My insurance says 3 years. I've had some that I've had 10 years or more but I had a suprise a few years ago when Bo ripped one of his mw's right open, it was 7/8 years old, a good brand and still looked fab from the outside but on the inside the filling had disintegrated, it wasn't the thick fluffy wadding anymore, just strings of it holding patches together mostly round the seams, I'd have been none the wiser that I was effectively using a no fill (there was none left over the back) when I thought I was putting a mw on him.
Now I treat older mw as light-med just thought I'd share
