wear Key brand..and i wash em only about twice a year..(that sounds terrible) so I can't really say that they aren't as warm after being washed...I NEVER put em in the dryer though...I'm gonna look into those cuddleduds though..they sound pretty good!  Actually I have a one of those coats from Cabella's that is windproof and repels water...I wear that over my coveralls on the really bad days...that's what really keeps me warm..love that coat.[b
