Durable, Comfortable, Stain Resistant, Excellent

I've been wearing the Dickies double-knee work pant for about 5 years now and wouldn't trade them for the world. Unlike normal khakis, these pants are highly durable, extremely comfortable with extra room in the legs, they do not suffer from static cling, and they repel stains expertly. What I like best, though, is that they look nice enough for wearing in a business casual environment, while standing up to the wear and tear of work requirements.
