Benjamin, those are my favorites now. I wear them in black, very dark green, and brown, so they must suit me.
I have thinner trousers that I use for summer backpacking. These are just slightly nicer, slightly thicker, and slightly more citified.
These meet your five points. I would say that these are quick drying, although not as quick as my thinner summer trousers.
For some reason, mine seem to be shrinking around the waistline now, although maybe that is me.
