How is the fit on that jacket? The size guide on Sitka says 42" to 45" chest, which would seem to be way too big for me. I have an older, 2019 maybe, Jetstream that is large and it fits me pretty well. I am a 41 regular.
The fit is pretty good, I have 40” chest, and I was able to comfortably layer under it. I couldn’t imagine a medium being able to accommodate much if any layering even for me.
I was recommended through many here on rokslide to buy a XL, boy were they wrong. I was SWIMMING in the goddamn thing.
