I'm 5'9'' 158lbs, 32" waist, 40" chest and have used Marmot products for twenty years, always in a medium. The problem with the Pro Tour is that the chest is so snug that it renders the jacket's features useless.
Try and fit a pair of skins in the interior mesh pocket (like the Exum guide in the video) and the jacket will bulge out becoming very awkward and uncomfortable. The same is true of the exterior pack pockets, anything more than a thin pair of gloves and an energy bar and the fit of the jacket is compromised. Further, even minimal layering makes it all worse.
So, if you order true to size, don't expect to be able to do anything like the Exum guy in the video review. Even a pair of gloves, like the ones he was using, made me feel like I had some strange growth protruding from my chest. Also, the hood is quite snug, definitely not helmet compatible, if that's a deal breaker for you.
I didn't try a large, but because the sleeve and torso length were true to size on the medium, I would imagine that the large would still be a goofy fit... a better torso size perhaps, albeit with too long sleeves.
In short, the pro tour doesn't know what it wants to be. On the one hand, it has features that mimic a technical hard shell; on the other, it fits like a performance cross country ski jacket. Unfortunately the jacket comes up short on both accounts.
