Familiarity: I've put it through the wringer
This jacket looks quite underwhelming when you first take it out of the box( incredibly thin, almost fragile). But it is tough,REALLY is packable in your jersey, and blocks wind.
Fit is tight (as in, when you stand straight up it is very restrictive across the chest), but on the bike the fit is perfect with no flapping. Zippers are super high quality and re-enforced.
