MicroTex is GOOD stuff, but, for serious, mountain wear while backpack hunting in typical BC conditions, which can and do range from 80*F-ish to 0*F-ish during our main seasons from mid-August to mid-November, I have a pant that is the best I have found in 50 years of buying/wearing such gear.

This, is the "Wild Things" gear, comes in "Multicam", a medium green, darkish grey and, IIRC, black. They call it "softshell" and these are NOT "cheap", but, from what I have seen of Sitka Gear and a LOT of other gear, they are the best I know of.

For most mountain hunting, I like these, stagged high like Bullbucker's pants, good gaiters, silk and/or merino base layers, according to personal tastes/needs, in varying weather and so far, they have served me right well in most wet conditions.

Google "Wild Things" and see what you think, I have found them a great outfit to buy FINE gear from and only wish that they still would do custom sizing orders as they formerly did.
