What is this fabric?

I'm looking for a grey sport coat fabric, dont want it to look like orphaned suit jacket, but also dont like tweed or herringbone or heavy pattern as it will be a year-around jacket.

I checked out sharksin, birdseye, hopsack, but this one seems to be none of them?

It seems to a good old twill, just a more pronounced one.

I was thinking twill when I saw it I have a stretch or knit twill jacket that’s similar
