I haven't used Sitka, but I bought some Kuiu and Core4Element for some hunts in NZ and Spain over the years. Those are the only hunts where I needed some technical type clothing where lightweight and controlling moisture were an issue.
Core4Element went out of business, but their clothing was head and shoulders better then Kuiu or Sitka, for significantly less money.
I have some Sitka and Core4Element outer wear/soft shells that I’ve used over the past 10yrs and my experience/opinion is the other way around. I bought all of it on “after season” sales, so price I paid for each piece was a good bit lower than MSRP, but the Sitka was still more expensive. I found the “price/performance” of each was pretty accurate, meaning their prices were reflective of performance. Just my opinion.
