This is a surprisingly heavy duty shirt, and i like it. I'm 6'2", 200lbs, 44" chest, 34" waist. I got a large, and the fit is on the looser side. The shoulders and sleeves are generously cut, and I have more than enough room to move and reach. The waist is a bit boxier than I'd like, but this is a common issue I have with shirts, so I can't get too upset about this shirt having an average cut. The underarm gussets are a nice touch and do help.Between the looser cut and the thick fabric, this is almost a shirt jacket, but It juuuust barely is a heavy shirt. The fabric is soft, warm, and thick cotton, which feels great but also is too warm for me to wear indoors if the room is warm. This is perfect for cooler days, splitting wood in the winter, and outdoors when it's 65 or cooler.
