I'm 5'11" and 180 pounds and ordered a medium. Overall they fit well, they actually go down to right above my ankle, which is surprising given I have to usually order "extra tall" to get my pants to do that. They are soft and well made. My only complaint would be that after a day of wearing them they definitely stretch out a bit. I usually wear them while I am sitting on my computer working and I get up and have what I like to call "**** pants" where the butt gets a saggy look to them and is not appealing. Once I wash them they will shape up again, but I really just can't be sitting in them for that long....that being said, I would order another pair 100x over they're so comfortable.
