I have some black 5.11's, but they just feel too "mall ninja" to me. I like the "business casual" look of 5.11 khakis. But mostly I wear jeans everywhere, so that's my prefered "tactical pant."
Actually I've tossed the idea around in my head that one could design a "designer jean" for men that would look stylish like it could be a name brand, but constructed with absolute sturdiness in mind: thicker width belt loops at appropriate places and with heavier, durable stitching and reinforced waist to support the weight of some of the more zealous EDCers out there with their carry gear all on the belt: pockets with the flat edge for knife and light clips, and using the most durable denim. Basically: a designer jean designed so that John Clueless Public will still like them, but made to last and will be the proper platform for a CCer with his EDC gear.
I even know a pro-gun friend from college who, IMHO, was the best dressed man on campus and who has a real business talent. I'm not much of a business guy, but the engineer in me knows that the jeans I like to wear (NOT skinny jeans, but not baggy work jeans either) while look and feel right, simply are going to wear out faster b/c they're not constructed to hold up under the load of my gun belt and gear. They're meant for a pro-forma belt and a guy's wallet, keys, and phone, and that's about it. They could be much better constructed for what the dept. stores charge for them.
But that's getting off topic.
The ideal tactical pant for us CCers is khaki cargo or denim jean that doesn't have the pocket arrangement of a tactical pant, but is made to hold up and last and is subtly designed in pockets, waist, and belt loops to support a man's EDC kit.
I've been mulling this over in my mind for the past 6 months or so. I KNOW there's a better way to do this, but I'm just trying to figure out what that is.
