I bought a 36W 30L, and they are looser and more relaxed than the Docker's Alpha Khaki pants, which are stiffer and a little  more narrow at the waist. The 36W feels more like a 37W. These are great pants for work, and just for kicking around. Soft, flexible, you can run down the street in them and not worry. Quick wash and air dry, steam them to get the few wrinkles out, good to go.

I am 5'8", stocky build with "rugby thighs". These are awesome pants.
