Pretty much all the other reviews have things right - fast shipping, good quality, looks as advertised...but the only part that I can comment on and advise is for the sizing.
I wear a 44R jacket, and according to the sizing here, that's a L. However, I know I typically were a XL jacket, and ordered that size. Prior to shipping, the contacted me to confirm sizing and their grid of measurements had the XL measuring even bigger than the original XL specs, which was fine too.
When I received the jacket, I put it on, and immediately it was hard to get my arms in the sleeves and wear, as it was tight across my chest. I was wearing a button down shirt and a medium weight sweater - not only should those fit in that size, but that's exactly what you may wear in the weather that calls for this coat.
The coat did fit, though snug, once I took off my sweater. Later, I put it on with my sweater, and it started to loosen up to wear for a few minutes. I put it on a third time and it was a little better.
Websites I have read talk about how leather can be tight by design and how to stretch leather by wearing it, so I will be putting on an extra layer or two to help the process. Other leather coats I've bought I was able to try on, but as this was on on the web, you may want to go for a larger size. I won't go so far to pull it or wet it or some of the other online suggestions, but some wear will loosen the coat up and not damage it.
The customer service and follow up for processing the order was good, and I have no question if I was was to exchange for a size up, there would be no trouble, but I don't know if that 2XL is going to be the better fit, since I don't wear that for any other jackets or coats. Plus the sheered lining in the sleeves and chest obviously add thickness, so that is a factor to consider.
All in all, sizes vary slightly from different manufacturers, and some of the more fitted motorcycle coats would definitely warrant a larger size, but I would say go with the size coat you normally wear because the inconsistent sizing they provide may be confusing, and if you don't know you size, then err on the cautious side and get one a little larger.
I really like the coat, but I think I'll love it once it breaks in and fits a little better, or should I say regularly.
