I don't know all that much detail about EZ models, so I'll give model numbers later. The fabric is probably a 10 oz. It's definitely a suit I could wear nearly year round. I'm not sure what the fabric is -- it's a 100% wool, but as far as count I'm not sure. I tried looking in the tag but nothing was listed. I assume it's not a 15milmil15, because there wasn't that tag inside of it. It might be a 140s though. It's definitely a 130s or higher -- it is very smooth and very soft, but the weave it fine so it doesn't have any real "shininess" to it. The fabric is dark gray (gunmetal?). It has a windowpane pattern, with the panes being about 2 inches in width and 2 1/2 in height. The windowpanes are dark blue and almost a rust type color. The lines are basically right on top of one another. So, it's a really nice, subtle effect. The pants are a medium rise, with a medium cut through the thigh tapered down to about an 18" leg opening. Double pleated (very shallow pleats) with quartered pockets. I like the pants a lot, and might have my tailor take them in a bit in the thigh if that is possible. Things that stood out? The shoulder is a bit more sloped than the Zegnas I've tried on at Saks. In addition, the padding is a bit lighter than most Zegnas I've seen, including the ones in their Boston boutique. It is very thin, light padding. At the sleeve head there is the standard Zegna roping, which gives it some structure. This suit isn't too much different than most high end Sartorial suits; it's just a really, really nice one. I like it a lot.
