More "skinny fit" than "slim fit"
Very nice fabric and well constructed, however I would class them as more of a "skinny fit" than a "slim fit". They are pretty tight in the thighs, which for me causes them to bunch up at the knees. I would recommend buying both this and the straight fit to compare, and then return the one that you don't like.
For reference, I got these to replace a (now discontinued) pair of J.Crew urban slim fit chinos, and even though I went a size up (30x32 from 29x32), they are still much tighter.
