Vertx tactical pants. Super mobility with articulated knees and gusseted crotch. The best cargo pocket design out there. The pockets are inset so they don't bag out as conspicuously as normal cargo pockets, and the flap closure with no buttons or velcro is secure but easy to get in and out of.
They come in a heavier weight cotton canvas with a little lycra, and a lighter weight poly/cotton ripstop. I like both. The cotton is a little softer and more comfortable. The blend is lighter (but not necessarily more breathable), dries faster, is more stain-resistant and stays new looking longer, but is stiffer and less soft, especially when new.
Order by MEASURED waist size, not your usual pants size. Get an actual measuring tape and hold it the way you want the waist of the pants to fit, then order that size.
I've tried 5.11, but don't like the design as much and the cut doesn't work for me. If the waist fits, the butt and thighs are too tight and binding. If the rest of the pants fit comfortably, the waist is huge.
