Crazy guy checking in…
I machine washed and dried an N-1 jacket a couple of years back... There was some slight shrinkage, but alas I didn't take measurements. I assume that could be avoided if washing on cold and line drying though.
I've not had any issues with the alpaca shedding after the wash/dry, aside from the typical amount it sheds anyway even when new.

Hey Guys, good to hear back from you!
Thanks for the input. Yeah I think that is my main concern, that the layers separate. I once washed a Daun jacket and some of the feathers got redistributed in the confines of the jacket. So now there are some places where there’s no insulation and in other places too much. My vest doesn’t really “need” to be washed. I just kind of want to see how it will look, fade/patina afterwards.
I haven’t made up my mind yet but I’m 70% at this point that I’ll do it. Will send pics after to show the outcome.
Until then,
