I like Lululemon's Utilitech ABC 5 pocket pants, they're like jeans but comfortable.
For real jeans, IH 555 21oz, IH 777 21oz, and of course, Momotaro 16oz Slubby Denim.
I also have selvedge 501s that come in a slim tapered cut, very rare to find in EU or US as most of their selvedge issues come in a straight or relaxed fit.
