A far as male pants/trousers go, your choices are basically jeans, corduroys, or khakis (chinos). Corduroys are uncomfortably warm, IME, and of the remaining two jeans are a clear winner for convenience: they don't need to be ironed (chinos look terrible as soon as they get even slightly wrinkled, jeans do not), and they better conceal small spills and stains. Not much more to it than that, for me.
