Great coat
Size: Large, Color: Black
Sizing runs true, the quality appears to be good. I ordered the black and the color is what I expected, it’s the perfect length. The weight and thickness is perfect for temperatures in the low 30’s and up. The coat is perfect for Business wear and casual wear

Nice Coat, But Could Better
Size: Medium, Color: Black
I like this coat overall. It fits really well, nicely tapered, and a good weight, but the fabric has a sheen to it, very noticeable in brighter light, which I'm not crazy about. It doesn't have any inner breast pockets, and I don't feel secure putting my phone in the side pockets. I did get lots of positive comments from friends.

Great style chose for any occasion
Size: Medium, Color: Black
Genuinely the perfect fit and great for the style I prefer. Great material and thick to keep you warm but not to hot. Black is deep and adds that depth that I am looking for
