I used to wear the German Army wool pants that could be purchased for cheap at surplus stores here in our country. Those pants were tough and standard wear in the woods. I do not know if they still make and import them. If you can find them, get them. They've got pockets...lots of pockets and some have suspender buttons.
Wool, even merino wool, makes me break out a bit. I can wear wool socks for a while. So, for me it is poly what ever. I love poly fleece. The Wisconsin Walmarche had some heavy duty fleece longjohns, that worked well. I have a cold weather tolerant body so I wear layers. I can shed layers and do so even at -20 if I'm moving. Snowshoeing, which was necessary to get work done will heat one up.
I like the gloves with the fingertips exposed that have mitten flaps that can be folded or unfolded over the fingers. That way you don't have to shed them to write, or reverse the plugged tip on your paint gun (tree marking) or put more staples in the staple hammer.
A heavy coat is only good for standing or sitting around, or (and this isn't a problem in the mideast) trudging back down a long slope after trudging up it. Layers are the thing to wear. Keep your feet warm and dry. I like the thinsulite boots. They come in different weights of thinsulite. They are less bulky than the Sorel pack boots. They are lighter too, so you can move quicker to stay warm.
I bet all that stuff is sold out by now. One needs to shop for it in October instead of waiting for the cold snap. Winter happens, except it hasn't done much in the PNW this year.
