Makes sense, will have to check if she tumbled it
I need to put my Paramo through the wash too, so useful advice.
I'm sure mine says 'don't tumble'
Have you redone the waterproofing, too? It makes it really slidy, which would reduce friction and shocks (and keep you drier, of course)
I have this problem with fleeces. I mostly wear natural fibres, but you just can't beat fleece for warmth and washability, so I put up with the shocks when I forget to kneel to take my jacket off.
i found silicone spray works on fleeces etc
