Still confused (re: fused versus unfused)

Something has been picking at me.  After scouring several websites (including this one), I understand a typical way to determine if the suit is fused is to check the chest area at a point between the shell and inner lining above the pockets (either rubbing, pulling or what have you). It seems to work great.  Going through my own suit selection and doing window shopping, I've tested the various brands and confirmed for myself what has been stated on this site, i.e., Canali, Armani Black Label, Zegna (regular) are canvas, Armani Collezioni, Z Zegna (Soft), and some other brands like Kenneth Cole, Tommy Hilfiger are fused. However, I have one black label Hugo Boss suit I bought four years ago.  The label says made in the USA.  Based on the standard "feel" test, the chest appears canvased.  I can pull the shell from the lining, move them in independant directions and feel a distinct middle layer which ends at the upper end of the chest pockets. Is it possible this particular Boss suit is canvas front?  Or maybe the glue has disentegrated (although I don't see any bubbling).  Below the chest pockets, I don't feel a middle layer, but the area feels thinner overall as if there's no middle layer at all.  Can anybody shed some insight on this? Is this an example of a semi-fused suit? Thanks in advance for any information.

I'm so crossed up now. I thought I was pretty sure I could identify a canvased suit by feel (got my hands on Canali, Armani Black Label, Vestimenta, Oxxford, Cantarelli, Zegna (regular)), but as I go through my collection of older, cheaper stuff again (including a junky navy blazer from Men's Wearhouse), I feel a distinct layer between the outer fabric and the inner lining (pinching the chest above the pockets). I can feel my way down and it feels like the layer ends at the inner chest pockets. I don't know enough to doubt the knowledge from the gentlemen here, so as such I'm doubting my own ability to discern the difference. I thought I had it, too.

The light just went on. Thank you very much. Yes, using that test, the results are consistent with what I've been reading. So that begs the question: what is that middle layer in a fused suit? I assume it's the floating canvas in a non-fused suit.
