Considering that this brand tends to be a bit hit-or-miss (mostly hit) I was apprehensive about the fit and sizing. These fit so well that I bought other colours and have no issue with the sleeve length (often cheaper brands have very short sleeves) nor with the length of the body of the shirt. They look great, the fabric quality is excellent, and the colours are compatible with a broad range of pants (you can't go past black pants, black jacket/blazer, and any colour of this underneath).

Nice feel

Special Size: Two Pack, Size: Medium, Color: A-wine Red/Dark Grey

I’m 5’8”, trim and athletic build. The sleeves are a tiny bit tight and would be unpleasant on a warmer than expected day, but for a cool day just fine. Nice fit. Feels pleasant to the touch.
