I would estimate it to best fit a Men's modern Medium- Large/ Large, depending on required fit. Generous chest measurement, waist is tapered in. The exterior wool is in good condition, no holes or stains.
So while the label lists this as a 44", it also wears as a 42". The condition is very good, just nicely worn in. There are no holes or tears inside or outside, and I've never added any pin or stitch-on badges.
