I am 6/5 250lbs and have the SKRE Ptarmigan in 3XL. It fits me like it should. Now, I have also put in the work to lose 60lbs this season because last year I couldn't zip up the Ptarmigan. I did return a Kuiu Kenai vest last week because the 3XL was too big for me. I do have another Gunmetal jacket that I have in 3XL that is now too big for me. It is possible that it could fit you, but you really don't know until you try. I have fund that I need the 2XL/3XL just to get the sleeve length more than anything. Hopefully that gives you some insight.
