Sleeves not in proportion
I ordered a Slim Small. This shirt is certainly light-weight, and the fit through the torso was okay. However, the sleeves seemed much longer than 34.25" and were far too wide. The sleeves are fit for somebody with much larger arms and wrists. I measured the shirt to be 16" around the bicep and 10" around the cuff, at least 1.5 inches too wide in both places.
