I did that awful thing some folks do, try-on in a brick-and-mortar store, then buy it on Amazon. I am 6-2 and 210 lbs. Am built like the guys in the listing photos. I am a 46 tall suit jacket but in Carhartt everything fits big. I got the large tall and it fits like a glove, even covers my long, monkey arms. It is light weight and pretty darn warm, I have fallen back on it as a liner under other winter parkas. Not too bulky for that purpose. Love it, just get the right size.
