This is technically a women's L or M, but the sweater is unisex anyway, so it doesn't matter. The measurements are:
24.5 in. (sleeve length; neck to wrist)
19 in. (chest)
22.5 in. (length)
I'm 5' 6'', 127 lb., and it fits me perfectly. I live in the South and it never gets cold enough here for this sweater, so I'm selling it. If you care about authenticity, this is the version that was made in the 80s with the correct pattern direction and 80% wool and 20& rayon. The new ones are known for stretching more as well as having the pattern going in the opposite way. In short, it's an inferior version. I should also mention that the one I'm selling is really thick and will keep you toasty in winter.
