+1 on next to skin -- very comfortable.

I sleep in my smartwool shirt and long johns. They're the best.
Me too.

I wash my wool stuff whenever it starts to feel crusty. Sometimes that means once a year and other times it's once a month.
Tempting, but I don't think my wife would allow it. It has me wondering if I really need to wash my merino stuff once a week, though. Maybe I could get more usage between washing.
The one knock I have on wool, merino or otherwise, is that it does not get along with velcro. You gotta be careful to keep them separate, especially in the dryer.
