22" neck With good length sleeve relaxed and bent
Size: 22" Neck 37"-38" Sleeve, Color: Flame
22" neck With good length sleeve relaxed that didn't walk up forearm when arm was bent.
For a fitted shirt. 22" neck was true to size but the waist is still quite large. Even with creative folding it was noticeably large waisted.
Fabric is high quality and vivid color that should last.
Price is Fair and a good value for this shirt.
Buttons fit easily into the holes but are secure and won't come out too easily.

Good fit and fabric quality, and the button color doesn't stick out too much.
Size: 17" Neck 35"-36" Sleeve, Color: Black
Unlike some competitor shirts, the buttons in these are not BRIGHT white. (Subtle buttons are better for my usee.) Fit and fabric quality are both very good.
