For people who are built a bit more powerful and have very thin forearms or wrists, this is a Super lumberjack shirt. I ordered the size S and could my mind. My big pillow stuffing under his shirt, constructed so that it reasonably snug, however, I have to open on the wrist the button, otherwise I will not be there by, and I'm really not big / strong , So unfortunately my skinny wrists do not fit in the size S through the sleeves - and when I draw plus a thin sweater under it, it is really tight at the wrists.
Conclusion: in the abdominal area, the shirt is a lot bigger, the smaller wrist. Since you have never taken on a working level!
