These jeans run very tight through the seat and front.  I have well over a dozen pants of identical size (various brands and styles, some also Dickies), and most all of them will fall off me without a belt.  I'm tall and lanky.  In these pants, I struggle to get a phone or keys out of the front pockets, and sitting down it's impossible.  Seeing as how these are active work pants, it only makes things more difficult and I avoid wearing them.  It's a shame because they're fairly robust and look decent.
