I ordered the "new charcoal" color and in person it is not as dark as it appears on the site.  It's a medium but unmistakable gray, not a dark gray.

I initially received an XL when I ordered an L, but exchanging that was painless.  I am 6'4", 200lbs and the L fits me very well--it's long enough to cover the waist, and comfortable but not baggy around the torso.

The coat itself is very high quality in construction and materials.  It is quite warm, especially when fully zipped up.  The front zipper and surrounding material are like a sweater, with buttons that close on top of it.  The four front button pockets are all usable, and there is room to slide your hands into warm wool pockets cut behind the lower front button pockets.

Overall the coat is both very stylish (with a bit of a military flair) and practical.  Happy to have found it.
