I am 6’, around 175 lbs, wear size 43 suits (when I can find them) and 34 inch pants. The large fits, arms and shoulders move easily, sleeves are long apparently by design but not uncomfortably so.
The jacket is nice and pliable, goes on easily, has enough pockets, and gives a decent degree of warmth for what it is. Construction is nice and tidy, the zippers work, the main zipper is nice and large so it works well. The smell is a good leather smell rather than the bad kind.
I like the absence of shiny parts and epaulets.
Against my disposition I give it five stars, because it pretty much is exactly what I wanted when I ordered it.
NB to Schott: If you use the menus to look at mens’ leather jackets, the 503VN shows up but not the 503, as far as I can see. If you look at all mens’ jackets the 503 shows up.
