I decided to go ahead and give the Filson stuff a shot. They were all 70+% off retail and they can be returned if I can't flip them so it's worth a shot.
What I got this run:
NWT Filson Double Tin Bibs W30 and W34.
NWT Filson Mackinaw Field Pants W38 and W42.
There is still some more stuff so I'm thinking about going back. A few more bibs in different sizes, like W46, W44 and I think W36. Flannel Lined Pants W34.
I also found a Filson Outfitter Jacket in Otter Green wool. Inside the jacket it says both made in US and made in Canada so I'm a bit confused.
PM me if interested in anything.
