They said it is about 17 micron. It is a very light fabric.I believe Trofeo is in the 130 range, although as well know Zegna refuses to give a super number because they posit that a cloth is more than just a micron measurement. Trofeo is also 8.5 oz, so be careful with the light fabric. I believe the Su Misura jackets are fully canvassed and are decently made. I've seen these jackets sold without the finishing, such as buttons and button holes sewn in, possibly in an attempt to give something similar to the oxxford system.
No, the tags were still on it and the pants unfinished. I think I got an older suit that was meant to be 'su misura' but hasn't been altered because nobody took it. Anyway it fits me perfectly, maybe just a little tight on the chest. I got it for a little more then 500 euros which is a true Christmas steal in my opinion.Su Misura is Italian for "your measurement". It appears you have bought a suit that someone had made for themselves and did not take.
