+1 - although it did take some getting used to, but now I love riding in a jacket that's cut tight to the body, gives that "suit of armor" feel. After a few rides the jacket starts forming to your body and becomes very comfortable.
Exactly. Although with the slimmer fit on a bike, the body length becomes really important. Too long, and the jacket (especially if not fully broken in) rams up into your chin and bubbles out in the front. That's the one thing to look out for with the slimmer cuts. The bottom zipper gap (like on a J-100 or an Aero Board Racer) solves that issue even if the jacket is a touch on the longer side.
