I usually commute in my work pants (Dickies 874 traditional work pants). I find the Dickies to be more comfortable than jeans due to the smaller/flatter seams. My longest commute in work clothing so far has been a 26 mile or so round trip with hills. If I have a clean pair of work pants and a clean pair of jeans and I'm going out to run an errand I'll always grab the Dickies. However if it's just a short trip the jeans are usually fine. Are you required to wear jeans for your commute or just don't want to try out other types of pants?
