Very comfortable.
What I was most impressed with is that it feels light. The construction appears to be of good quality. I would be very surprised if the coat didn't last me. The coat is very soft. It feels luxurious but subdued (controlled).
It is just right.
I use it mostly to the office with business-casual attire (collared shirts, sweaters, chinos or jeans) but never with suits. It is not an overcoat.
I am not a flashy person and I don't seek (or need) attention from others. But it is good to enjoy great "quiet" luxury pieces. And this is good for me.
I'm 6ft, 176lb, pants size 33W, 34L, chest 39"
I'm considered slim. So with that said, I got it in M-size
The fit is almost "tailored fit"
