A beautiful, current Ermemegildo Zegna jacket. $3,195 retail. Cut from Zegna's signature luxury "Crossover" wool/silk/linen blend. In solid middle gray.

In excellent pre-owned condition, however there are a couple pulls at the rear vent; see last photo.

The tagged size is 52R EU. This usually translates to about a 40R-42R US but this leans closer to a straight 40R, maybe even a large 38R.

Crossover Fabric 

Introduced in 2013, it’s an unprecedented lightweight fabric. 15 micron superfine wool, prestige silk and light linen are blended to create a fabric with extraordinary properties. The unique combination of the finest natural fibers creates suiting that is extremely lightweight, breathable, sumptuously soft, and ideal for both summer and cool weather.
