I hate buying new pants. It's the worst. I also hate pants in general. I find them very constricting - I move around a lot, am very flexible, and like to have a solid range of motion. Pants always seem to stop me from moving my legs the way I want to. Well, without ripping the pants. I saw the "Smart 360 Flex" on these pants, read a little about it, thought they sounded good, and figured I'd give them a try. I ordered them, they came in, I put them on, and I promptly ordered three more pairs in different colors. These are the most comfortable dress pants in the history of time. They look both from a distance and upon closer inspection like normal dress khakis. But they feel like you're wearing pajama pants. You can move however you want in them and they stretch very naturally to your every movement. They fit perfectly as expected, not too tight, super comfortably, and move however you want. All while looking perfectly professional. Plus, they have one of the smoothest zippers on the fly ever. Love a smooth zipper fly. Hate clunky ones that lead to you standing at a urinal, zipper gets caught, you have to move it back and forth a few times to free it, meanwhile you look like a creep in the middle of the bathroom. Never gonna happen with these pants. They also have a weird security pocket on the side of the right pocket. For people that use them, I'm sure it's a great feature. For people that don't (like me), it's practically unnoticeable so it's a non-issue. And far better than those stupid security pockets that some pants have inside the regular pocket, like a pocket in a pocket, which always just led to my keys getting stuck in them and me having to turn out the entire pocket just to get them out. So this is a much better solution.Long story short - Professional looking khakis that feel like pajama pants. Best damn dress khakis ever.
