Great in colder weather when my unlined jacket doesn't cut it. It's made very well and looks great. I usually wear a 44 but this jacket fit me better in a 42 (originally purchased the 44 which fit but on the larger side of OK). I haven't had the opportunity to wear it in colder weather yet but I can tell you that I feel the warmth against my body when just trying it on. This was not a cheap purchase for me but I don't regret paying for quality when it's there. This jacket is worth it.

This coat is great; looking at the details of its construction, you can see that it will definitely last a very long time. Also goatskin will still look beautiful when it gets old. The most comfortable temperature range for this coat is about 35F-45F (with only a t-shirt and a dress shirt underneath); also it will not become too hot even the temperature rises to 50F+. With some light layering, it can be worn comfortably in 20F-30F. For chest sizing, I usually get 42R for suit and size 40 fits me well; it has enough room to add one big sweather, and does not look bulky at all. So I think getting 2inchs below your suit jacket size would be roughly correct. Initially when I bought this jacket a few months ago (still summer time), I thought the sleeve is somewhat too long and was considering having it shortened. Fortunately I didn't do that, because winter coat is usually worn on top of some other cloth so the sleeve has to be a little longer than summer coats. The only suggestion i would make is about the cell phone pocket on the right: that is not useful at all, would be much better if its replaced by a real chest pocket or some large mesh pocket.

I live in Houston and have to wait for cold enough weather. I'm praying for cold fronts. Love the style, feel, and quality.
