Repeat customer here for these well-fitting work pants- I've tried cargo pants from 5.11 and Duluth Trading Company (will edit to get specific model numbers) and found those to be far too baggy in the legs despite having a waist size that fits.

 In the last 3 1/2 years I've purchased about 10 pairs of the WP594 and get about 2-3 years' use from them. Over time they tend to shrink in length, maybe 1/2" or so and the fit around the legs lets looser and somewhat baggy and if these were more expensive I'd probably opt to let out the hem to get a bit more life out of them. The fabric is durable and despite the fabric softening over time the color holds fairly well (for the black and navy blue anyway.)

 For some background I'm just under 6',  between 145 and 150 lbs. with a 28" waist and 20" thighs (thanks to many hours spent bicycling.)
I've found this pant in  30x32 to be a nearly ideal fit. For what it's worth I wear the same size Levi 501 jeans and the fit is remarkably close but the WP594 may sit ever so slightly higher above the hips.

 I abhor loose fitting clothes and my only gripe is the seat of these pants could be made to fit a bit less loose but otherwise I'm thrilled with how these fit at the waist and legs. The well-placed and sized cargo pockets are always helpful since I carry a personal and work phone plus whatever small work-related items need a temporary home!
 An added bonus is a small gap in the right side cargo pant pocket flap that's designed to hold a pen or small marker that makes it easy to reach down and get to it without having to bother with opening the flap.

As a testament to these pants' comfort in the winter months I find it easier just to bike the 10 miles to work in these pants rather than bother with some bike-specific solution; they're flexible, wind-resistant and warm enough to use as-is even in sub-40 degree weather.
