They shrink a bit. You can't dry them in a machine dryer and they should be washed by hand or on gentle cycle.
For what it's worth, I always machine dry all my merino, although I do it on low heat with small loads of similarly light stuff.
I basically do a load of all my baselayers, boxers, socks, and a few tshirts, and leave all the heavy stuff with buttons, straps, velcro, etc out - I wash that small load on gentle with a very gentle biodegradable soap, and then dry it on low heat.
So far my merino has held up VERY well under this kind of washing, even if it goes against the manufacturer's guidelines.
