Yes, feels 1/2 canvassed. It's light though so there's not a lot going on.
For the record, and not that anyone really cares, but I did decide to keep it. The fit, especially in the arms and shoulders is really quite good and I while I have several navy coats none is a traditional blazer. Will make a good coat to stuff in the luggage in my business rotation. I've been traveling with some nicer coats quite a bit and it's showing.
