Plenty of good brands of wool offered here. Something to think about is WIND. How dense is the wool, will it stop wind, is there some kind of wind blocker on the inside of the wool, or are you layering up properly to address various weather situations. I think movement vs non movement had been covered.
I like a use wool all the time. From old German Army Surplus, to KOM, to Filson, to Day One and a few others. Current wool hunting pants would be my Day One's. I do like my KOM but they are a smidge tight now.
Best of luck on your north woods hunt!
