I used to be able to get away with jeans at work, but for the past few years I've needed business casual.
For pants, I've got some UB Tech, Orvis, and Weatherproof Vintage, that I picked up at Costco. The Orvis, and Weatherproof, look the best, and all three will be wrinkle free. They have all held up to a moderate amount of abuse, but I haven't been out hiking/climbing in them. Both the UB tech, and Orvis, have a zippered pocket on the right thigh, but its not a bulging cargo pocket.
They might be worth checking out to see if they meet your needs.
