If you’re predominately hunting from stands in cooler weather, there are a TON of better clothing options than KUIU. You’re asking for two drastically different types of clothing to do one thing. Clothing for tree stand hunting can be done fairly inexpensive. That leaves clothing for doing drives/stalking that will be breathable and waterproof. Another tough scenario as “breathable” and “waterproof” just don’t go together. Stone Glacier is the latest hunting company to the “breathable and waterproof” line of clothing. I plan on testing it this fall. Breathable and truly waterproof doesn’t exist and you can spend a small fortune trying to find it. (Ask me)
I have clothing systems from KUIU, Sitka, Kryptek, Stone Glacier and First Lite to cover every imaginable weather scenario while hunting the mountains. They are all excellent technical clothing companies designed primarily for mountain hunting. (And I don’t think KUIU is superior to any of them in materials or design.). Some of the best “cross over” clothing I own is the Sitka Whitetail line and the First Lite Stand hunting line. This stuff is made for the tree stand but performs pretty decent on moderate exertion hunts as well.) I use it almost exclusively in the tree stand but have used the Sitka EVII on moose hunts, deer hunts and caribou hunts. IMO buying a bunch of “extreme mountain hunting clothing for your uses as you list them is not the best option. But hey, if you want KUIU and you gotta have KUIU, go for it. Just know there are better options for the money.
