I like my jackets small and my pants HUGE! So when I got a burton jacket in XL it was WAY too big (for me). It was a Sig Fit so the L prob would have fit but Burtons sleeves seem to be super long. Cuz even on my M the sleeves go 3-4 in past my hand yet the jacket fits almost perfectly ( a little small) a Team Fit M would prob be perfect for me.
Anyways a Burton XXL would prob be good for you.
