I was a bit surprised like others at how slim fit it was, especially the sleeves (I'l 6' 190lbs). However I still have plenty of room to move around in the shoulders and such so I am not gonna stress it, I dig the way it fits me. The jacket has got plenty of space for pocket tool & you iPod and it looks sweet. If anything, I wish it had a bit higher waterproofing but unless you plan to spend the whole day on your back it doesn't really matter. If you're a thin guy and tend to swim in other jackets, this is definitely one you should try out.
