I'm 5'11" and 275 (losing weight via cycling) and the XXL is snug, but not overly so. It's only been cold enough to justify once this season (52F) versus compression base layers or arm warmers and it's been a great jacket. Very wind resistant as it was super breezy but my torso wouldn't have ever known it. My guess is with proper base layers, a neck gaiter, and a good stocking cap I'll be able to ride well into the winter on good weather days.
The pockets make sense and I like the cut of cycling jackets (long in the back). Because of the cycling cut I don't know that I'd wear it around town. I picked it up in white/black (I've been a ninja cyclist for the year I've been cycling). My lady saw me in it and didn't know who I was as I never wear white and its snugness definitely shows off my relative lost weight.
