I already pm'd you about a core ss shirt, but I just replaced my Forest Early Season Whitetail jacket with a Kuiu Guide Jacket and would now be willing to part with it also if you are interested. It's a L or XL, I'd have to check to be sure which.
My fault. I replied to another member with a very similar wtb posting...
I have the ESW jacket and a Sitka Core short sleeve shirt both in Forest pattern that are no longer part of my system. Shoot me a price of you're interested.
