Another great post RJ. I used to wear wool when winter hiking all the time. It's excellent in bad weather. The only real disadvantage to me is that it's heavier than fleece. It does last a lot longer.

May need to add sheep to the farm after I get goats. OTOH I'm not sure who would spin the yarn and make anything from it. My wife don't do making clothes.

They do produce a decent amount of meat however. I've looked some at Kathadin sheep (called hair sheep). They are pretty large and produce a good milk which make some killer cheese.
