Have you looked at the Kuiu Kennai insulated jacket?

I borrowed one from a mate a couple of years ago for a winter Tahr hunt and i went a bought my own straight after as I was so impressed with it.
I am 6" 90kg and have a 112cm chest and the Large fits perfect as they make them slightly oversized to accommodate layers underneath. I can also fit my Macpac ultralight down underneath still too and is now my go to combo when winter hunting.
They are expensive full retail, but if you get one on sale they are well priced.
