It’s just not the most comfortable cotton
Size: 16.5" Neck 34"-35" Sleeve, Color: Blue Bay
Looks good, fits well, but it’s just not the most comfortable and breathable material. It’s the short you ll grab last in your closet

Too large, too plastic-y
This shirt was supposed to be "regular fit" but "mega obese" is more like it, absolutely nothing in common with the picture. Also the fabric was polyester-plastic-shiny, I don't believe that it's almost pure cotton.
