The leather jackets are great in both colors. I initially got the black jacket. The leather is a bit stiff in the beginning, but that's normal for cow hide. The fit is exactly as described. I went with the chest values as main determinator for the size I chose. This is recommended in their instructions and a very informative sizing video, which I highly recommend.
I have long arms, so the jacket was a perfect fit. In any case, the zippers make it a snug fit, in particular when wearing gloves, so even with shorter arms, the jacket works out well when riding. The zippers are of good quality (YKK). The silver zippers on the black jacket are a bit flashy for me, but it is a certain style that some people like. I actually bought the dark brown jacket on a huge sale since it is more to my likings with its dark zippers (making it more suitable to wear on a casual evening out for me). Both were the same perfect fit. I am super happy with these jackets. They were perfectly warm at freezing temps, up to 50s. I removed the inner lining, and the jacket does not become floppy and loose. Note that it has pockets for pads, which I own, and this adds a lot to safety. But the pads are pretty visible in some areas if the jacket is proper fit. But then, this is a riding jacket for me, and I don't ride for 10 minutes to some biker hangout, then return 3 hours later. I ride, mostly cruising at 25-50 mph. For this, these jackets are perfect in my opinion.
