I think this covers all the bases- synthetic fiber from DT, and expressly business casual. There are also some "covert cargo pants with pockets concealed along the thigh inseam - 5.11 and REI have examples.

Note that some of DTs Fire Hose items are treated for water repellancy. That has worked for me, which is no surprise since for the last few seasons I have been digging indoors in air conditioned comfort. I generally prefer synthetics in outdoors situations although sometimes traditional cotton denim seems to work the best - just don't get caught in bad weather.
