For reference, I'm 5'9" and about 170-175lbs, I bought a Large with 34" inseam, and it fits me very nicely. It feels more like a second skin, in that it isn't too tight or too loose, and the length is perfect for me, as it falls to the ground when I'm barefoot and has just enough ground clearance when I wear shoes. Overall, I am VERY pleased with these pants and I'm heavily considering buying more colors!.
