Recently bought some pants from Old Navy. For reference, I'm a 30 in Levi's and 29-30 in LEC pants, usually a 29 in Gap/ON stuff.
Straight-Leg Cords (Link is from Old Navy Canada)
Great cords for the price, fit is nice, not too slim, not too loose, quality is okay. Bought them in Carbon, 29x30.
Slim-Fit Khakis
Slimmer than the cords, but not constricting at the thigh. Very narrow opening, not ideal for boots. Fabric is on the lighter side, not the best for Canadian winter. Still a great pair of slim pants. Bought them in Lively Ivy, 29x30.
Broken-In Khakis
These are terrible. Very loose, waist is at least two sizes too big. Maybe if you size down a lot, they would be decent? Bought then in Uniform Blue, 29x30.
