These pants are fantastic.  I got them to be used as a cheap alternative for mountain bike pants when the weather is colder, but they turned out to be so much more.  I use these pants for everything.  They are work pants, chill pants,  biking pants, and even look good as casual pants with the right shirt.  Dickies quality really shows with these pants.  The only small negative is when they come they are super stiff.  It looks like when they are manufactured they dip them in a vat of starch.  Solution for that is just to wash them once or twice before wear and they'll be all set.  I'm 6'1" and 180 lbs and I ordered the size 36x32 and they fit perfect with a bit of extra room in the waist just the way I like them.  These are billed as work pants so be mindful that the sizes do run a bit on the small side.  I can usually wear a 34 waist, but I always size up with "work" clothing since they seem to run small.  So if you want them to be comfortable and not on the tight side I would recommend sizing up one size.
