if you look after it i'd say C. i think i slightly shrunk my torm baselayers a few years back (and i probably gained a few lbs) but i was washing them in with the rest of my normal clothes at the time and probably got stuck in a 60 degree wash at some point.
sportwool washed with wool detergent* at 30 degrees shouldn't change at all. It's how i wash all my merino stuff now and it keeps it perfect.
