Asked to trade me for something I had. Seemed like a good deal.
In comparison with my US Wings VIP (size M), this Expedition (a 42 R) has shoulders cut just a little wider, and so the seams hang off my shoulders just a little bit, between 1/2" and one inch. The sleeves are correspondingly cut very slightly shorter, but still end up at the same place as with my US Wings, the first knuckle on my thumb.
This is admittedly a "screen accurate" look, and some of my other jackets also are cut this way, including my "go to" jacket which I've had for 27 years.
If I were physically in the G&B store, I would probably try on a 40 L, to try to get the seams right at my shoulders (and the L to get the sleeve length right).
However, this particular configuration works very well, and offers very good freedom of movement. I'm certainly not complaining.
Otherwise, well-matched pebble-grained goatskin in a very dark brown, two-piece gussets under the arms, action-pleats sewn into the lining, and all the other stuff that comes with an Expedition.
I still like my US Wings VIP jacket, and still hold it in the highest regard.
I wasn't LOOKING for another jacket, but it seemed like this poor unwanted jacket was somehow looking for me. It only seemed humane to give it a better home.
Both this G&B as well as your US Wings suit you quite well!
