To tell if a jacket is fused, just pinch a piece of the cloth from the chest area between your fingers. Roll it around a little to make sure you've grabbed the thinnest amount possible and don't have a hold of more than one layer.
Then do the same with the sleeve or back panel. If the two areas are the same thickness (ie; nothing fused to the chest), then you have a canvassed coat. If the chest feels thicker and firmer, you've got a fused coat. A canvassed coat should have a distinctly different middle layer - the "floating" canvas.
If the sleeve or back is thicker than the chest, then you have a really serious problem! [:0]
