These are exactly what I was looking for. When I received my package, I took out the bag and immediately thought these were going to be too heavy for me. I generally prefer more lightweight pants for work, however I put these on and knew they would be just fine. Yes, the material is a little more "stiff" than your usual black slacks, however they are breathable, and that's what's important to me. And because of the material, I'm going to guess they will hold up to movement and last a bit longer. I can't speak for durability yet, but if you're looking for black slacks, definitely give these a go. They're only that much more awesome that they make in-between sizes too. :)
