I have a peak lapel jacket i'm selling. I loved it but I don't ever wear them and impulse bought it on sale. It's gorgeous, cut super slim but looks really sharp and modern. I'm pretty sure its full canvas. I tried the pinch method and felt 3 layers. There are shoulder pads which look a little awkward if you move your arms around a lot because of the tight sleeve but looks really cool otherwise. It does feel a little restrictive though as far as movement, especially in comparison to other jacket's I've checked out, but that could be because of the wool/full canvas construction.
