First, the jacket is solidly built and the color is great as is expected with anything from Schott.
Unfortunately, this jacket seems to have a design flaw. Behind the neck, across the shoulders, the leather flips up, creating a fold of leather that prevents the jacket from draping smoothly when it is worn. Attempting to simply pull the leather flat did not work. There is too much leather in this area with nowhere for it to go..
I cannot upload photos with this review, but if you look closely at the stock image of the back of the jacket, near the neckline, you can see the area in question. It's not a smooth line from shoulder to neck and its worse in person. It is an approximately 1/2-inch deep fold of leather.
After receiving the first one of these, I notified Schott of this issue and they confirmed "something isn't right" with it and I should return or exchange it. I exchanged the jacket for another of the same and the replacement jacket had the exact same issue. Since I could no longer attribute the flaw as possibly being a one-off construction problem, I returned the jacket for a refund. Schott customer service is top shelf and the whole process was easy.
Regarding fit, I am 5' 11" and 190-200 lbs. With a 43-inch chest, I am right at the cusp of a L or XL. I got a L which allowed for me to comfortably wear a t-shirt under the jacket and that is all I'd ever wear under it anyway. The jacket fit snug like a glove and sleeve length was perfect. If I wanted to wear a hoodie or sweater under the jacket, I'd need a XL.
